ABSTRACT:
Ethylenically unsaturated polymerizable oligomers, which are particularly useful in printing plate compositions, comprise backbones formed by the removal of hydrogen from hydroxyl groups and having bonded thereto both carboxylic acid groups and ethylenically unsaturated, free radical polymerizable groups, these last two groups bonded to the backbone through the reaction of isocyanate groups.
