Active energy ray-curable composition and use thereof

#This application is a National Stage of International Application No. PCT/JP2015/085607, filed Dec. 21, 2015 (claiming priority based on Japanese Patent Application No. 2014-258500, filed Dec. 22, 2014), the contents of which are incorporated herein by reference in their entirety.

#The present invention relates to an active energy ray-curable composition and use thereof.

#In an ene-thiol based photocurable resin composition which is a radical polymerization type photocuring system, active thiyl radicals are regenerated even when radicals are deactivated by oxygen. Said composition therefore has advantages such that polymerization inhibition caused by oxygen that occurs in acrylic materials does not occur, that the used amount of a photopolymerization initiator can be reduced, that volume shrinkage at the time of curing can be reduced, that curing can be done in a short period of time, i.e., from a few seconds to a few minutes after the initiation of polymerization, and that cured products of thick-film having a thickness of 1 mm or more can be produced, and is gathering attention as a photocurable material (Non-Patent Document 1).

#The active energy ray-curable composition of the present invention (this composition may hereinafter be simply called “the composition of the present invention”) is characterized by comprising (A) diallyl 1,4-cyclohexane dicarboxylate, (B) a compound having two or more mercapto groups, and (C) a polymerization initiator.

#[Components]

#The components that constitute the composition of the present invention are explained as follows.
