A radiation sensitive composition for forming a colored layer, a color filter containing a colored layer formed from the composition, and a color LCD device containing the color filter are provided to prevent the generation of residue or the contamination of background in case of development and to improve the adhesion to a substrate even with a small amount of exposure. A radiation sensitive composition comprises a colorant; an alkali-soluble resin which comprises a copolymer of an unsaturated compound containing a phenol structure represented by the formula 1 and other copolymerizable unsaturated compounds; a multifunctional monomer; and a photopolymerization initiator, wherein the other copolymerizable unsaturated compounds comprise at least one selected from an N-substituted maleimide, an unsaturated compound represented by the formula 2, an acidic unsaturated compound, an aromatic vinyl compound, an indene, a macromonomer having a (meth)acryloyl group at one terminal, an unsaturated carboxylate, an unsaturated aminoalkyl carboxylate, an unsaturated glycidyl carboxylate, a cyanovinyl compound, an unsaturated amide, a vinyl carboxylate, an unsaturated ether and an aliphatic conjugated diene. In the formula 1, R1 is H or a C1-C4 alkyl group; R2 to R6 are identical or different one another and are H, OH, a C1-C6 alkyl group or a C1-C6 alkoxy group; B is -COO- or -CONH-; and m is an integer of 0-3. In the formula 2, R7 to R12 are independently H, a halogen atom, OH, a hydroxymethyl group or a carboxyl group. |
