ABSTRACT:
It has been found that excellent quality photopolymer printing plates having hardness, flexibility, resilience, abrasion resistance and resistance to alcohol-based inks can be prepared from photopolymer compositions comprising a liquid polymer containing at least two terminal olefin groups attached to the polymer through a combination of at least two ether, thioether, ester, keto or amide groups, from about 1 to about 50% by weight based on the polymer of at least one ethylenically unsaturated monomer, from about 0.1 to about 10% by weight of a photoinitiator and about 0.01 to about 2% of a stabilizer.
