Cationically polymerizable compositions containing sulfonium salt photoinitiators and odor suppressants and method of polymerization using same

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