There are disclosed a light-sensitive composition which comprises (A) at least one water-soluble polymer selected from a cationic water-soluble polymer having a phenyl group substituted by a vinyl group at a side chain of the polymer and a water-soluble polymer having a phenyl group substituted by a vinyl group and a sulfonate group at a side chain of the polymer, and (B) at least one of a photopolymerization initiator and a photo-acid generator; and a light-sensitive composition which comprises at least one cationic monomer having two or more polymerizable unsaturated groups in the molecule, at least one polymer, and at least one of a photopolymerizable initiator and a photo-acid generator. |
