Title:
PROCESS FOR PRODUCING OPTICAL RECORDING MEDIUM AND STAMPER CAPABLE OF LIGHT TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2005/048253
Kind Code:
A1
Abstract:
A process for producing a laminate-type optical recording medium, in which a stamper capable of light transmission can be easily detached from a resin constituting an interlayer without application of excessive load in the production of an optical recording medium according to the 2P method to thereby enhance the production efficiency. There is provided a process for producing a laminate-type optical recording medium, comprising the steps of coating a recording layer containing organic dye superimposed on a polycarbonate substrate with a precursor of ultraviolet cure resin; superimposing thereon a stamper capable of light transmission with indented configuration and made of a nonpolar material polypropylene; curing the ultraviolet cure resin; and easily detaching the stamper capable of light transmission without application of excessive load to thereby transfer the indented configuration onto the resin layer.
