ABSTRACT:
Photopolymerizable compositions using sulfonium salt photoinitiators to effect polymerization of cationically polymerizable monomers as essentially the sole polymerizable material additionally include an organic sulfur compound scavenger to reduce or eliminate the sulfur odor generated upon photodecomposition of the sulfonium salt photoinitiator. The scavengers are simultaneously activated by the electromagnetic radiation to react with the organic sulfur compound concurrently generated and are selected from the group consisting of aromatic ketones, benzoin compounds, aryloin oxime compounds, organic peroxide compounds, and benzil compounds.
