PURPOSE:To obtain a photosetting composition good in dyability with an acidic dyes, capable of forming a superior filter, and good in storage stability by incorporating a monomer having an optionally substituted amino group which has a photopolymerizable double bond, and a specified (meth)acryloyloxyalkyl maleate. CONSTITUTION:The photosetting composition contains a mixture of the monomer represented by formula I (R<1> is or methyl or ethyl, X is -O- or -NH-, Y is 1-4C straight or branched alkyl, and R<2>, R<3> are each 1-4C alkyl), and a monomer for cross-linking represented by formula II (R<4> is same as R<1>, and each of each of X, Y is same in both formulae), and in addition, as necessary, (meth)acrylic acid and (meth)acrylate in an amount of <=50wt% of the sum of the monomers of formulae I and II; and further, a sensitizing dye and a photopolymerization initiator. This photosetting composition is stable in the dark for one month or more, good in balance between photosensitivity and dyability, and developable with an aqueous solvent, and suitable for forming a color filter adapted to a color video camera. |
