Abstract
A photosensitive composition comprising: PA1 (A) 35-80 weight parts of a phosphorus-containing hydrophilic copolymer made by copolymerization of a mixture of (a) 5-30 weight % of a phosphate ester group-containing unsaturated monomer, (b) 40-90 weight % of a conjugated diene monomer, and (c) 0-50 weight % of other monoolefinically unsaturated monomer; PA1 (B) 65-20 weight parts of a thermoplastic elastomer; the sum of (A) plus (B) being 100 weight parts; PA1 (C) 5-300 weight parts of a photopolymerizable ethylenically unsaturated monomer; and PA1 (D) 0.1-10 weight parts of a photopolymerization initiator. The photosensitive composition is useful for a photosensitive rubber plate and a flexographic printing plate.
