Abstract
This invention relates to a substrate for optical disc recording media which contains a UV-curable resin film between a transparent film and a thermally-decomposing high molecular film, the UV-curable resin film being formed with a UV-curable resin composition comprising given quantities of: PA0 (a) a polybutadiene having acrylic or methacrylic group at one or both ends of the molecule, PA0 (b) a hydroxyalkyl acrylate or methacrylate, PA0 (c) an acrylic- or methacrylic-group-containing diluent, and PA0 (d) a photo-polymerization initiator.
