Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
93 words
In a photopolymerizable composition comprising (a) at least one nongaseous ethylenically unsaturated compound having a boiling point above 100° C. at normal atmospheric pressure and being capable of forming a high polymer by photoinitiated addition polymerization, (b) an initiating system activated by actinic radiation, and (c) a preformed macromolecular binder wherein the improvement comprises incorporation into said composition an additive of a heterocyclic triazole or its hydrate of the formula: ##STR4## wherein R is an orthoarylene or orthoarylene substituted with alkyl, cyclic alkyl, aryl, aralkyl or alkaryl and X + is a cation.
Claim 2
Dependent Claim
93 words
