The present invention is directed to new, energy-efficient photoinitiators in the form of organic sulfur-containing compounds. The present invention is also directed to a method of generating reactive species which includes exposing one or more photoinitiators to radiation to form one or more reactive species. Also described are methods of polymerizing unsaturated monomers, methods of curing an unsaturated oligomer/monomer mixture, and methods of laminating using the photoinitiators of the present invention.
[ What is claimed is:] [1.]1. A photoinitiator having the following formula: rein x is an integer from 1 to 4, and R.sub.1 and R.sub.2 each independently represent H-- .sub.2 N-- where R is an akyl group having from one to six carbon atoms; a chalcone; HSO.sub.3 -- or NaSO.sub.3 --; wherein at least
