ABSTRACT:
Novel water-soluble triazine photoinitiators and bifunctional ionic photoinitiators having an anion containing a photo-labile halomethyl-1,3,5-triazine and a photoinitiator cation are described. The ionic compounds are good photointiators for initiating free radical and acid sensitive reactions. The ionic photoinitiators are easily synthesized and eliminate the need for a combination of photoinitiators in a photocurable, photopolymerizable, or photoacid sensitive composition. Additionally, the radiation-sensitive compounds are resistant to migration in photosensitive compositions. The ionic photoinitiators are particularly useful in compositions for use in printing, duplication, copying, and other imaging systems.
