PURPOSE:To provide the titled composition composed of a specific reaction mixture, a polyfunctional (meth)acrylate compound, a specific (meth)acryl compound and a photo-polymerization initiator, polymerizable and curable in air with ultraviolet irradiation and giving a coating film having excellent transparency and dyability, etc. CONSTITUTION:The objective composition can be produced by compounding (A) a reaction mixture of (i) a compound having >=2 mercapto groups per one molecule (e.g. pentaerythritol tetrathioglycolate) and (ii) a compound having >=1 epoxy group and >=1 acryloyl group per one molecule (e.g. acrylic acid 9,10-epoxidized oil) with (B) a polyfunctional (meth)acrylate compound (e.g. dipentaerythritol hexaacrylate), (C) a (methy)acryl compound having one triazine ring per one molecule and (D) a photo-polymerization initiator. |
