ABSTRACT:
Photopolymerizable composition consisting essentially of (A) at least one ethylenically unsaturated monomeric compound, (B) at least one 2,4,5-triarylimidazolyl dimer, (C) sensitizing amount of at least one polymeric sensitizer, weight average molecular weight 10,000 to 300,000, which is the reaction product of (1) a reactive photosensitizer and (2) a reactive polymer as defined herein, and (D) optionally an organic polymeric binder. The compositions are useful in photoresists, chemical milling, toning films and printing plates.
