Patent ID: 7871685

Claim:
A method for producing an optical recording medium, wherein the optical recording medium comprises: a supporting substrate; a light transmission layer, which transmits a laser beam; and an information layer formed between the supporting substrate and the light transmission layer, wherein the method comprises: applying a resin composition on the information layer by a spin coating method to form a coating film, wherein the resin composition comprises: (A) a radical-curing urethane (meth)acrylate produced by a process comprising reacting (a-1) a compound having three or more isocyanate groups binding to an aliphatic carbon atom per one molecule thereof and (a-2) a polycaprolacton-modified hydroxyethyl (meth)acrylate; and (B) a radical-curing monomer having a viscosity of 400 mPa·s or less at 25° C., (D) 0.1-5 wt. % of at least one lubricant selected from the group consisting of a fatty acid ester-based lubricant, a silicone-based lubricant and a fluorine compound-based lubricant; and curing the coating film by irradiating the coating film with an ultraviolet light or an electron beam to form the light transmission layer.
