PURPOSE:To obtain a curable composition which can give a transparent high- strength information recording disk, etc., by mixing an unsaturated cycloacetal group-containing compound with a mercapto group-containing compound and a compound having a triazine ring and a reactive unsaturated bond. CONSTITUTION:The purpose curable composition is obtained by mixing a compound (A) having at least two unsaturated cycloacetal groups in the molecule with a compound (B) having at least two mercapto groups in the molecule (e.g., dipentene dimercaptan) and a compound (C) having at least one triazine ring in the molecule and at least two reactive unsaturated bonds per triazine ring (e.g., N,N'-bisacryloylmethyl-N,N',N'',N'''-tetrakismethoxymethylmelamine). This curable composition can be suitably used as, e.g., a material for video disks. |
