Abstract
Abstract Disclosed are a photo-setting colored filter composition, a color filter, a process for the preparation thereof, a curable resin, and a curable resin composition. The photo-setting colored filter composition of the present invention has an excellent photo-curability, miscibility in the composition, and developability. The curable resin composition is excellent in stability of the composition, tackiness, developability, sensitivity, anti-strippability, and hydrolysis resistance compared to conventional curable resin compositions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
54 words
A photo-setting colored filter composition comprising a curable resin comprising a (meth)acrylic resin having unsaturated groups obtained by a reaction of a resin having carboxylic groups with a compound having an alicyclic epoxy group and a (meth)acrylic group, photo-initiators, coloring materials, and optionally dispersants for the coloring materials, copolymerizable monomers and/or prepolymers, and solvent.
Claim 2
Dependent Claim
100 words
The photo-setting colored filter composition of claim 1, wherein the resin having carboxylic groups has structural units represented by general formula (I): wherein R 1 is a hydrogen atom or methyl group, R 2 is an alkylene radical having a carbon number ranging from 2 to 12, R 3 is a divalent radical having a carbon number ranging from 1 to 10, R 4 is a hydrocarbon group having a carbon number ranging from 1 to 20 which may be branched, n is an integer ranging from 1 to 20, and m is an integer ranging from 1 to 5.
Claim 3
Dependent Claim
34 words
The photo-setting colored filter composition of claim 1 or 2, wherein said compound having an alicyclic epoxy group and a (meth)acrylic group is selected from the group consisting of 3,4-epoxycyclohexyl methylacrylate and 3,4-epoxycyclohexyl methylmethacrylate.
Claim 4
Dependent Claim
31 words
The photo-setting colored filter composition according to one of claims 1 to 3, wherein said (meth)acrylic resin having unsaturated groups has a number average molecular weight ranging from 1,000 to 50,000.
Claim 5
Dependent Claim
40 words
The photo-setting colored filter composition according to any one of claims 1 to 4, wherein said (meth)acrylic resin having unsaturated groups has an acid value ranging from 10 to 300 KOH mg/g and preferably from 20 to 200 KOH mg/g.
Claim 6
Dependent Claim
38 words
The photo-setting colored filter composition according to any one of claims 1 to 5, wherein said (meth)acrylic resin having unsaturated groups has double bonds ranging from 1.0 to 3.5 mol based on 1 kilogram of said (meth)acrylic resin.
Claim 7
Dependent Claim
80 words
A colored filter comprising: a) a substrate having a surface portion, wherein said substrate is formed of a transparent material selected from the group consisting of glass and synthetic resin ; and b) a multiplicity of colored filter elements distributed in a predetermined pattern on said surface portion of said substrate, at least one, and preferably each, of the colored filter elements being formed of a photo-setting colored filter composition as defined in any one of claims 1 to 6.
Claim 8
Dependent Claim
124 words
A process for the preparation of a colored filter which comprises a step of : (a) mixing a curable resin comprising a (meth)acrylic resin having unsaturated groups as defined in any one of claims 1 to 6 with coloring materials, and additionally copolymerizable monomers and/or prepolymers, dispersants, and a solvent to prepare a dispersed liquid, (b) adding photo-initiators to the dispersed liquid to produce a photo-setting colored filter composition, (c) forming a layer of the colored filter composition on the surface of a transparent substrate, (d) selectively exposing the layer of the photo-energy and developing the resultant layer for forming the multiplicity of discrete filter regions of the photo-setting colored filter composition distributed in a desired pattern on the surface of the transparent substrate.
Claim 9
Dependent Claim
106 words
A curable resin comprising a (meth)acrylic resin having unsaturated groups obtained by a reaction of a resin having carboxylic groups having structural units represented by general formula (I): wherein R 1 is a hydrogen atom or methyl group, R 2 is an alkylene radical having a carbon number ranging from 2 to 12, R 3 is a divalent radical having a carbon number ranging from 1 to 10, R 4 is a hydrocarbon group having a carbon number ranging from 1 to 20 which may be branched, n is an integer ranging from 1 to 20, and m is an integer ranging from 1 to 5.
