Реферат: PHOTOPOLYMERIZATION COMPOSITIONS COMPRISING AMINE-SUBSTITUTED PHOTOSENITIZERS AND N-HETEROCYCLIC COMPOUNDS BEARING AN N-OXY SUBSTITUENT Abstract A co-initiator composition for use in an improved photopolymerization composition, element and method is dis-closed. The co-initiator comprises an amine photosensitizer and an N-heterocyclic compound containing from 5 to 14 nuclear atoms and bearing an N-oxy substiuent, such compound being responsive in the presence of the photo-excited form of said photosensitizer to form a free radical.
