Abstract
It has been found that printing elements can be prepared from a water-soluble photopolymer composition comprising (1) a water-soluble thermoplastic ethylene oxide copolymer containing 50-96% ethylene oxide, (2) from about 0.5 to about 25% by weight based on the ethylene oxide copolymer of an ethylenically unsaturated monomer having its unsaturation in the form of at least two ##STR1## groups, wherein R is hydrogen or a C.sub.1 -C.sub.3 alkyl group, and (3) from about 0.1 to about 10% by weight based on the ethylene oxide copolymer of a photoinitiator thermally stable at temperatures up to about 150.degree. C. The above described photopolymer composition can be thermoformed, such as by extrusion or compression molding.
