POLYTHIOL EFFECT CURABLE POLYMERIC COMPOSITION

摘要

The invention relates to curable compositions and their use in printing plate production. The novel composition comprises (1) 10 to 97% by weight of said composition of a C-C unsaturated polymeric resin, C-C saturated polymeric binder or a mixture thereof, (2) at least 1% by weight of material (1) of at least one cross-linkable C-C unsaturated compound; and (3) 0.1 to 35% by weight of material (1) of a thiol. It is used by exposing it to actinic radiation to cure the composition in image areas followed by removal of the unexposed composition.
