Photopolymerizable compositions comprising
(a) at least one ethylenically unsaturated compound.
(b) at least one organic polymeric binder,
(c) optionally at least one photoinitiator and
(d) at least one constrained N-alkylamino aryl ketone compound as defined, e.g., bis (6-julolidyl ketone), bis-(N-ethyl-1,2,3,4-tetrahydro-6-quinolyl)ketone, etc. The compositions, in layer form, are useful in photoresists, including projection speed photoresists, printing plates, drafting and toning films, etc.
