Title:
COLORED RESIN COMPOSITION, COLORED FILM, COLOR FILTER AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/059359
Kind Code:
A1
Abstract:
Provided is a colored resin composition: which contains (A) an alkali-soluble resin, (B) a coloring material, (C) an organic solvent and (D) a photosensitizer; which contains at least zirconia compound particles as the coloring material (B); and in which the crystallite size of zirconium nitride contained in the zirconia compound particles, as determined from the half value width of a peak derived from the (111) face in an X-Ray diffraction spectrum using CuKα radiation as the X-Ray source, is 10-60 nm. This high sensitivity colored resin composition exhibits improved transmission properties for light in the ultraviolet region (wavelength 365 nm) which is commonly used in photolithography, and improved shielding properties for light in the visible region.
