LIGHT COPOLYMERIZING ELEMENT

摘要

An aqueous developable photopolymerizable element having improved rate of development consisting essentially of (a) an ethylenically unsaturated monomeric compound, (b) an organic acidic polymeric binder, (c) a photoinitiator or photoinitiator system and (d) at least 2% by weight based on weight of solids of an organic compound or salt of an organic compound as defined. The elements are useful as photoresists, printing plates and for preparation of proofs and lithomasks.
