Color filters

An LCD color filter fabricated by curing a photosensitive resist resin composition comprising:

• (A) 1-100 weight parts of at least one dye selected from the group consisting of the following dyes (a) or (c):
• (a) dyes containing a photopolymerizable substituent of the formula (1):
• D—(A—Yn1)n2 (1)
• wherein D is a chromophoric nucleus,
• A denotes a connecting group of one of the formulae (19) to (22), in which parenthesized recurring units may be combined together at random:
• wherein one of R26 and R27 represents a hydrogen atom and the other denotes a hydroxyl group;
• and r1 and s1 each stands for an integer of from 1-10,000;
• wherein R28 to R31 independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, or a halogen atom;
• and r2 stands for an integer of from 1-10,000;
• wherein r3 stands for an integer of 1-10,000,
• wherein R32 to R37 independently represent a hydrogen atom, a halogen atom, a hydroxyl group, —SH, an amino group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxyl group, a substituted or unsubstituted alkylamino group, or a substituted or unsubstituted arylamino group;
• and a1, b1 and c1 each stands for an integer of from 0-10,000, Y is a photopolymerizable group of one of the formulae (2)-(7)
• wherein R1 to R4 independently represent a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aralkyl group, or a hydrogen atom;
• R5 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group, or a hydrogen atom;
• R5 is a hydrogen atom or a methyl group, provided that if R5 is a methyl group, then R5 is a hydrogen atom;
• and R6, R7 and R8 independently represent a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkoxy group, a halogen atom, or a hydrogen atom,
• n1 is 1-10,000 and n2 is 1-10,
