ABSTRACT:
Curable composition containing (1) at least 20% by weight monoalkenyl aromatic-diene copolymer resin; (2) at least 2% by resin weight of at least one monomer substantially compatible with said resin and having at least one cross-linkable C--C-double bond; (3) 0.1 to 35% by resin weight of polythiol containing at least two-SH groups per molecule; and, (4) a curing agent. The disclosure is directed primarily at printing plate production and the composition contains 0.01 to 10% by resin weight of photoinitiator and the monomer is an addition photopolymerizable polyethylenically unsaturated acrylic or methacrylic acid ester containing two or more acrylate or methacrylate groups per molecule or mixtures thereof. In an alternate form low molecular weight liquid rubber polymer may be included in the compositon. Other materials such as stabilizers may also be present.
