LIGHT-SENSITIVE PHOTOPOLYMERIZABLE COMPOSITION CONTAINING POLYMER WITH ETHYLENIC UNSATURATION IN THE SIDE CHAIN

摘要

A light-sensitive composition comprises (A) a polymer comprising structural units represented by the following general formula (I): (I) (wherein R1 represents a hydrogen atom or a methyl group; R2 represents a hydrogen atom, an alkyl group or an aryl group; and Z represents a bivalent connecting group having at least 3 non-metallic atoms in the main chain); (B) a monomer or an oligomer having at least two polymerizable ethylenically unsaturatred double bonds; and (C) a photopolymerization initiator. The light-sensitive composition has high sensitivity and is excellent in stability of sensitivities such as storage stability, temperature dependency and latent image sensitization.
