HALOMETHYL-1,3-5-TRIAZINES CONTAINING A SENSITIZER MOIETY

The present invention relates to photosensitive compounds that generate free radicals upon exposure to light. Halomethyl-1,3,5-triazines are known to be initiators for a number of photochemical reactions. However, the spectral sensitivity of these initiators is limited. It would be desirable to inco...

Zusammenfassung:	The present invention relates to photosensitive compounds that generate free radicals upon exposure to light. Halomethyl-1,3,5-triazines are known to be initiators for a number of photochemical reactions. However, the spectral sensitivity of these initiators is limited. It would be desirable to incorporate a sensitizer moiety into a halomethyl-1,3,5-triazine to increase the spectral sensitivity thereof. This invention provides radiation-sensitive organo-halogen compounds having a photo-labile halomethyl-1,3,5-triazine moiety and at least one sensitizer moiety within one molecule. The compounds of this invention are good photoinitiators, and compositions containing them can be used in printing, duplicating, copying and other imaging systems.
