RADICAL PHOTOCURING OXYGEN INHIBITION REDUCER, RADICAL PHOTOPOLYMERIZABLE COMPOSITION CONTAINING RADICAL PHOTOCURING OXYGEN INHIBITION REDUCER, COATING CONTAINING RADICAL PHOTOCURING OXYGEN INHIBITION REDUCER, AND METHOD FOR CURING SAME

摘要

[Problem] The purpose of the present invention is to provide a coating composition in which oxygen inhibition at the surface of a coating can be reduced for a photoradical composition that uses a radical photopolymerization initiator which is prominently affected by oxygen inhibition, and said coating composition being curable without any problems, even in the presence of oxygen. [Solution] A radical photopolymerizable composition characterized by containing at least a radical polymerizable compound, a radical photopolymerization initiator, and a 9,10-bis(alkoxycarbonylalkyleneoxy)anthracene compound comprising an ester group represented by general formula (1). (In general formula (1), A represents a C1–C20 alkylene group optionally branched by an alkyl group. R represents a C1–C20 alkyl group that is optionally branched by an alkyl group, is optionally a cycloalkyl group, or is optionally substituted with a hydroxy group, and in which some of the carbon atoms are optionally substituted with oxygen atoms.)
