PROBLEM TO BE SOLVED: To provide an active energy ray-curable resin composition suitable for forming a product having small warp, high hardness and excellent in durability at high temperature and high humidity, especially a light transmission layer of an optical recording medium, and to provide such product, especially the light transmission layer of an optical recording medium.SOLUTION: An active energy ray-curable resin composition has a structure represented by the formula (1) and contains 100 pts.mass of a polymer component containing an acryl polymer having the weight average molecular weight of 8000 to 30000 (A) of 5 to 50 mass% and a radical polymerizable compound (B) of 50 to 95 mass%, and 1 to 20 pts.mass of a photoinitiator (C), and the radical polymerizable compound (B) contains a compound having two or more (meth)acryloyl group in a molecule. (1), where R represents any of a substituted or unsubstituted alkyl group, a cycloalkyl group and an aryl group, and a substituent represents any of an epoxy group, a hydroxy group, a cyano group, an amino group and a carboxyl group. |
