BACKGROUND 1. Field of the Invention This invention relates to novel fluorinated dyes or colorants having high solubility and low viscosity in halogenated, especially fluorinated, solvents. The dyes or colorants of the present invention have shown to improve the performance of electrophoretic displays.

2. Brief Description of Related Art The electrophoretic display (EPD) is a non-emissive device based on the electrophoresis phenomenon influencing the migration of charged pigment particles in a solvent, preferably a colored dielectric solvent. This type of display was first proposed in 1969. An EPD typically comprises a pair of opposed, spaced-apart plate-like electrodes, with spacers predetermining a certain distance between them. At least one of the electrodes, typically on the viewing side, is transparent. For the passive type of EPDs, row and column electrodes on the top (the viewing side) and bottom plates, respectively, are needed to drive the displays. In contrast, an array of thin film transistors (TFTs) on the bottom plate and a common, non-patterned transparent conductor plate on the top viewing substrate may be used for the active type EPDs.

An electrophoretic dispersion composed of a dielectric solvent and charged pigment particles dispersed therein is enclosed between the two plates. When a voltage difference is imposed between the two electrodes, the pigment particles migrate by attraction to the plate of polarity opposite that of the pigment particles. Thus, the color showing at the transparent plate, determined by selectively charging the plates, may be either the color of the solvent or the color of the pigment particles. Reversal of plate polarity will cause the particles to migrate back to the opposite plate, thereby reversing the color. Intermediate color density (or shades of gray) due to intermediate pigment density at the transparent plate may be obtained by controlling the plate charge through a range of voltages or pulsing time.

EPDs of different pixel or cell structures have been reported previously, for <BR> <BR> example, the partition-type EPD [M. A. Hopper and V. Novotny, IEEE Trans. Electr. Dev. ,<BR> Vol. ED 26, No. 8, pp. 1148-1152 (1979) ], the microencapsulated EPD (US Patent Nos.

5,961, 804 and 5,930, 026 and US applications, Serial Number 60/443,893, filed January 30,2003 and Serial Number 10/766,757, filed on January 27,2004) and the total internal reflection (TIR) type of EPD using microprisms or microgrooves as disclosed in M. A.

Mossman, et al, SID 01 Digest pp. 1054 (2001); SID IDRC proceedings, pp. 311 (2001); and SID'02 Digest, pp. 522 (2002).

An improved EPD technology was recently disclosed in co-pending applications, US Serial Number 09/518,488, filed on March 3,2000 (WO01/67170), US Serial Number 09/606, 654, filed on June 28,2000 (W002/01281) and US Serial Number 09/784,972, filed on February 15,2001 (WO02/02/65215). The improved EPD comprises isolated cells formed from microcups and filled with charged particles dispersed in a dielectric solvent. To confine and isolate the electrophoretic dispersion in the cells, the filled cells are top-sealed with a polymeric sealing layer, preferably formed from a composition comprising a material selected from a group consisting of thermoplastics, thermoplastic elastomers, thermosets and precursors thereof.

Other types of displays, namely magnetophoretic displays (MPDs) and electromagnetophoretic displays (EMPDs), are disclosed in co-pending applications, US Serial Number 60/367, 325, filed on March 21,2002, US Serial Number 10/394,488, filed on March 20,2003, US Serial Number 60/375,299, filed on April 23,2002 and US Serial Number 10/421,217, filed on April 22,2003. The magnetophoretic display generally comprises display cells sandwiched between two layers of substrate and filled with a magnetophoretic dispersion wherein the pigment particles are magnetic but not charged.

The display is driven by a magnetic field. At least the substrate layer on the viewing side is transparent. In the electromagnetophoretic display, the display cells sandwiched between two substrate layers are filled with an electromagnetophoretic dispersion wherein the pigment particles are both charged and magnetic. One of the substrate layers, preferably on the non-viewing side, is coated with a conductive layer facing the filled display cells. The display is driven by a combination of electric and magnetic fields.

The substrate layer on the viewing side is transparent.

For all types of displays, the dispersion contained within the display cells is undoubtedly one of the most crucial parts of the device. The dispersion, as stated earlier, usually is composed of pigment particles dispersed in a colored dielectric solvent or solvent mixture. The composition of the dispersion determines, to a large extent, the longevity, contrast ratio, switching rate, response waveform, threshold characteristics

and bistability of the device. In an ideal dispersion, the dispersed pigment particles remain separate and do not aggregate or flocculate under all operating conditions.

Furthermore, all components in the dispersion must be chemically and electrochemically stable and compatible not only with each other but also with the other materials present in the display, such as the electrodes and sealing and substrate materials.

The dispersing medium may be colored by dissolving or dispersing a dye or colorant in the dielectric solvent or solvent mixture.

Halogenated solvents of a high specific gravity have been widely used in EPD applications particularly in those involving an inorganic pigment, such as TiO2, as the charged whitening or coloring particles. The halogenated solvents of a high specific gravity are very useful in reducing the rate of sedimentation of the pigment particles in the solvent. Fluorinated solvents are among the most preferred because they are chemically stable and environmentally friendly.

However, most dyes or pigments are not soluble in fluorinated solvents particularly perfluorinated solvents having a high boiling-point. For example, phthalocyanines are highly desirable colorants due to their high extinction coefficients and chemical stability ; but they are normally insoluble in most solvents, particularly insoluble in fluorinated solvents. Substitution on the ring with an organic group such as an alkyl or fluorinated alkyl may improve the solubility in organic solvents, particularly fluorinated solvents. However, the solubility is not sufficiently high and is also strongly temperature dependent. As a result, the EPDs colored by this type of dyes typically show poor shelf-life stability and narrow operation temperature latitude.

Certain soluble perfluorinated Cu phthalocyanine dyes have been disclosed in US Patent No. 3,281, 426 (1966). The process for the preparation of these dyes involves heating a mixture of an aromatic starting compound and a perfluoroalkyliodide at a temperature in the range of from 200°C to 350°C. The reaction is performed in an autoclave or a pressure ampoule due to the pressure developed. This synthesis involves <BR> <BR> complicated reaction conditions (e. g. , high pressure and temperature) and long reaction time and has a low yield. Other phthalocyanine derivatives (US Patent Nos. 6,043, 355 and 5,932, 721) show improved solubility in various organic solvents or even in water, but not in highly fluorinated solvents.

A group of fluorinated silicon (IV) phthalocyanine and naphthalocyanine dyes are disclosed in US applications, Serial Number 60/381,263, filed on May 17,2002 and Serial Number 10/439,428, filed May 15,2003. However the solubility of the fluorinated Si phthalocyanine and naphthalocyanine dyes in perfluorinated solvents, such as HT-

200, is still limited and the viscosity of the resultant electrophoretic dispersion containing this type of dyes is relatively high.

33.15 Gm of EB 60ohm (UCB, Smyrna, GA), 32.24 gm of SR 399tu (Sartomer, Exton, PA), 6 gm of EB1360 (silicone acrylate, UCB, Smyrna, GA), 8 gm of Hycar 1300x43 (reactive liquid polymer, Noveon Inc. Cleveland, OH), 0.2 gm of IrgacureT" 369 (Ciba, Tarrytown, NY), 0.04 gm of ITX (Isopropyl-9H-thioxanthen-9-one, Aldrich, Milwaukee, WI), 0.1 gm of Irganox 1035 (Ciba, Tarrytown, NY) and 20.61 gm of HDDA (1, 6-hexanediol diacrylate, UCB, Smyrna, GA) were mixed thoroughly with a Stir-Pak mixer (Cole Parmer, Vernon, IL) at room temperature for about 1 hour and debubbled by a centrifuge at 2000 rpm for about 15 minutes.

The microcup composition was slowly coated onto a 4"x4"electroformed Ni male mold for an array of 72, um (length) x 72 lim (width) x 35 um (depth) x 13 lim (width of top surface of the partition wall between microcups. A plastic blade was used to remove excess of fluid and gently squeezed into"valleys"of the Ni mold. The coated Ni mold was heated in an oven at 65°C for 5 minutes and laminated with the primer coated ITO/PET film prepared in Section A above, with the primer layer facing the Ni mold using a GBC Eagle 35 laminator (GBC, Northbrook, IL) preset at a roller temperature of 100°C, lamination speed of 1 ft/min and the roll gap at"heavy gauge". A UV curing station with a UV intensity of 2.5 mJ/cm2 was used to cure the panel for 5 seconds. The ITO/PET film was then peeled away from the Ni mold at a peeling angle of about 30 degree to give a 4"x4"microcup array on ITO/PET. An acceptable release of the microcup array from the mold was observed. The thus obtained microcup array was further post-cured with a UV conveyor curing system (DDU, Los Angles, CA) with a UV dosage of 1.7 J/cm2.

C: Filling and Sealing with a Sealing Composition 1 Gm of an electrophoretic dispersion containing 6% by weight (dry weight) of the TiOz particles and a dye or colorant prepared from the examples above in an amount as indicated, in HT-200 (Solvay Solexis) was filled into the 4"x4"microcup array prepared from Section B above using a #0 drawdown bar. The excess of fluid was scraped away by a rubber blade. The filled microcups were then overcoated with a 10% rubber solution consisting of 9 parts of Kraton G1650 (styrene-ethylene/butylenes-styrene block copolymer, Shell, TX), 1 part of GRP 6919 (hydrogenated styrene block copolymer, Shell), 3 parts of Cab-O-Sil TS-720 (treated fumed silica, Cabot Corp., IL), 78.3 parts of Isopar E (hydrocarbon fluid, Exxon Mobil) and 8.7 parts of isopropyl acetate, by a Universal Blade Applicator and dried at room temperature to form a seamless sealing layer of about 2-3, um dry thickness with good uniformity.

Sample 8.1 had 2.15% by weight of P6B dye (from Example 3.1) and 0.55% by weight of R30 dye (from Example 3.3). Sample 8.2 had 0.98% by weight of a CuPc-

C8H17 dye prepared according to US Patent No. 3,281, 426 and 2.02% by weight of PK1 dye (from Example 6.1). Sample 8.3 had 2. 1 % by weight of C3 dye (from Example 1.1).

Sample 8.4 had 1.23% by weight of a CuPc-C8F17 dye prepared according to US Patent No. 3,281, 426,2. 88% by weight of R30 (from Example 3.3) and 0.04% by weight of PK1 dye (from Example 6.1).

D: Lamination The ITO side of an ITO/PET conductor film (5 mil OC50 from CPFilms) was overcoated with a 25% by weight solution of a pressure sensitive adhesive (Durotak 1105, National Starch, Bridgewater, NJ) in methyl ethyl ketone (MEK) by a drawdown bar (targeted coverage: 0.6 gm/ft2). The adhesive coated ITO/PET layer was then laminated over the sealed microcups prepared from Section C above with a GBC Eagle 35 laminator at 70°C. The lamination speed was set at 1ft/min with a gap of 1/32".
