Abstract
Photopolymerizable compositions using sulfonium salt photoinitiators to effect polymerization of cationically polymerizable monomers additionally include a stable free radical to reduce or eliminate the sulfur odor generated upon photodecomposition of the sulfonium salt photoinitiator. The stable free radicals are soluble in the polymerizable material and are stable in the composition at ambient temperatures. Especially useful is 2,2-diphenyl-1-picrylhydrazyl.
