method for preparation of materials, on the effect of light to polymerize.

摘要

A photopolymerizable material suitable for use in the production of lithographic printing plates comprises a polymer which includes a plurality of structural units represented by the Formula: IMAGE in which R1 represents a hydrogen atom or a methyl group; R2 represents a hydrogen atom, an alkyl or substituted alkyl group, an aryl or substituted aryl group, or a heterocyclic or substituted heterocyclic group; R3, R4 and R5, which may be the same or different, each represents a hydrogen atom, a halogen atom, a cyano group, an alkyl group, an aryl group, an alkoxy group, an aryloxy group, an aralkyl group, an aralkoxy group or an alkoxy carbonyl group; Z represents a hydroxyl group, or an ester group and a is an integer greater than or equal to 1. The polymer may be produced by reacting a polymer of 2,3-epoxy propyl acrylate or 2,3-epoxy propyl methacrylate with an acid of formula IMAGE
