ABSTRACT:
It has been found that excellent quality photopolymer printing plates having resistance to alcohol-based inks can be prepared from photopolymer compositions comprising a chain extended, liquid, terminally olefinically unsaturated polymer; from about 1% to about 50% by weight based on the weight of the polymer of at least one ethylenically unsaturated monomer; from about 0.1% to about 10% by weight based on the weight of the polymer of photoinitiator; and from about 0.01% to about 2% by weight based on the weight of the polymer of a stabilizer.
