A radiation-sensitive composition for forming a colored layer, which comprises (A) a colorant, (B) an alkali-soluble resin, (C) a polyfunctional monomer and (D) a photopolymerization initiator, wherein the (B) alkali- soluble resin contains a copolymer formed from (b1) at least one selected from the group consisting of an unsaturated carboxylic acid or an anhydride thereof and an unsaturated phenolic compound, (b2) an N-substituted maleimide, (b3) an unsaturated compound having an allyl group and (b4) a specified unsaturated compound other than those which are described above. The novel radiation-sensitive composition for forming a colored layer can give a colored filter that is free of pattern failures such as chippings or undercuts in a pattern, that is excellent in adhesion to a substrate and that is also excellent in reliability of electric characteristics, and the like. |
