    Abstract: A radiation sensitive resin composition for a color filter, a color filter formed by using the composition, and a color LCD device containing the color filter are provided to improve voltage holding ratio and the solvent re-solubility of a dry coating and to prevent the generation of stain on a film after exposure and development. A radiation sensitive resin composition for a color filter comprises a colorant; an alkali-soluble resin; a multifunctional monomer; and a photopolymerization initiator, wherein the alkali-soluble resin is a copolymer of (b1) at least one selected from an unsaturated carboxylic acid, an unsaturated carboxylic anhydride and an unsaturated phenol compound, (b2) a compound containing an allyl group, and (b3) at least one unsaturated compound which is different from (b1) and (b2) and is selected from the group consisting of an aromatic vinyl compound, an indene, an N-substituted maleimide, a macromonomer having a (meth)acryloyl group at the one terminal of a polymer molecular chain, an unsaturated carboxylate, an unsaturated carboxylic acid aminoalkyl ester, an unsaturated carboxylic glycidyl ester, a vinyl carboxylate, an unsaturated ether, an unsaturated amide and an aliphatic conjugated diene. The alkali-soluble resin has a ratio (Mw/Mn) of a polystyrene-reduced weight average molecular weight(Mw) and a polystyrene-reduced number average molecular weight(Mn) by GPC is 1.0-2.0.

    Abstract: A radiation sensitive resin composition for forming a colored layer is provided to form a color filter which does not generate the stoving with high yield and to ensure high solubility to cleaning solvent after drying. A radiation sensitive resin composition for forming a colored layer comprises (A) colorant, (B) alkali soluble resin, (C) multi-functional monomer and (D) photopolymerization initiator. The alkali soluble resin(B) comprises a copolymer manufactured through a process of polymerizing a polymerizable unsaturated compound containing at least one selected from the group consisting of a polymerizable unsaturated carboxylic acid and a polymeric unsaturated carboxylic acid anhydride, in the presence a compound represented by the chemical formula 1.
