Abstract

Radiation-sensitive organo-halogen compounds that have a photo-labile halomethyl-1,3,5-triazine moiety and a polymeric moiety within the same molecule. The compounds of this invention are comprised of a polymeric moiety having attached or incorporated within its structure at least one 1,3,5-triazine nucleus, said triazine nucleus having at least one halomethyl substituent attached to a carbon atom of the triazine nucleus. These compounds are capable of being stimulated by actinic radiation at wavelengths of from about 250 to about 900 nanometers to generate free radicals and/or acids. The compounds of this invention are useful as photoinitiators in free radical polymerization reactions, oxidation-reduction reactions, or reactions sensitive to acid, and they also exhibit the capability to crosslink upon exposure to light.
