Title:
PHOTOPOLYMERIZATION INITIATOR AND PHOTOCURABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2007/126066
Kind Code:
A1
Abstract:
Disclosed is a radical photopolymerization initiator useful for polymerization of a radically polymerizable monomer. Also disclosed is a method for curing a photocurable composition wherein a radically polymerizable monomer is cured by being irradiated with near-visible ultraviolet light while using such a radical photopolymerization initiator. Specifically disclosed is a novel radical photopolymerization initiator containing an onium salt such as a specific sulfonium salt and an anthracene-9,10-diether compound. Also specifically disclosed is a photocurable composition containing such a radical photopolymerization initiator and a radically polymerizable monomer. This photocurable composition is excellent in adhesion, and is cured by being irradiated with near-visible ultraviolet light preferably having a wavelength range of 380-420 nm.
