Abstract
Abstract An improved photosensitive material is disclosed which comprises an addition polymer having a molecular weight of at least 5000 as a photosensitive component. The polymer comprises the following repeating monomer units (I) and (II): wherein R1 and R2 are individually hydrogen, alkyl or carboxylic acid; R3 is hydrogen, halogen or alkyl; R4 is hydrogen, alkyl, phenyl, or aralkyl; X is a divalent organic group selected from Y is unsubstituted phenylene or naphthylene, or phenylene or naphthylene having at least one of alkyl, nitro, carboxylic acid, cyano, sulfonic acid, hydroxyl, acyl, alkoxy or halogen; and n is 0 or 1.
