ABSTRACT:
Photopolymerizable compositions comprising (a) at least one ethylenically unsaturated compound, (b) at least one photoinitiator or photoinitiator system, (c) sensitizing amount of an N-alkylindolylidene or N-alkylbenzothiazolylidene alkanone as defined, and optionally (d) at least one organic polymeric binder. The compositions, in layer form are useful in printing plates, litho films, photoresists, solder mask and for making image proofs. The products show sensitization to visible light.
