Title:
COLORED COMPOSITION, METHOD FOR PRODUCING COLORED CURED FILM, COLORED CURED FILM, COLOR FILTER, AND ORGANIC EL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/171870
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a colored composition from which a highly reliable colored cured film can be produced even through a low-temperature process. The present invention further addresses the problem of providing a colored composition comprising said colored composition, a method for producing a colored cured film, a colored cured film, a color filter, and an organic EL display device. The colored composition comprises a black colorant, a polymerizable compound, and photopolymerization initiators, wherein the photopolymerization initiators comprise a photopolymerization initiator a having an absorptivity coefficient at 365 nm in methanol exceeding 1.0×102 mL/gcm and a photopolymerization initiator b having an absorptivity coefficient at 365 nm in methanol of 1.0×102 mL/gcm or less and having an absorptivity coefficient at 254 nm of 1.0×103 mL/gcm or higher, the content of the photopolymerization initiator b being 45.0-200.0 parts by mass with respect to 100.0 parts by mass of the content of the photopolymerization initiator a. A colored cured film obtained by curing the colored composition has a ratio of the maximum absorbance to the minimum absorbance in the wavelength range of 400-700 nm of 1.0-2.5.
