PURPOSE:To obtain a composition of outstanding long-term storage stability capable of giving tough cured products through readily curing by light or organic peroxide, by incorporating polythiol in a blend of diallylidene pentaerythrit and oligo(meth)acrylate. CONSTITUTION:The objective composition can be obtained by incorporating a blend of (A) diallylidene pentaerythrit and (B) origo(meth)acrylate with a molecular weight >=300, having in one molecule at least two (meth)acryloyl groups with (C) a polythiol in such an amount as to correspond to 0.1-1.5 equivalent of the thiol group per equivalent of the unsaturated bond in said blend. The component (B) is, e.g. a vinyl ester, urethane-acrylate resin. The component (C) is e.g. a pentaerythrit tetrathioglycolate. |
