Title:
TRANSPARENT STAMPER FOR FORMING OPTICAL MULTILAYER RECORDING MEDIUM AND METHOD FOR MANUFACTURING OPTICAL MULTILAYER RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP2004039136
Kind Code:
A
Abstract:
To provide a stamper which can inexpensively and easily be manufactured and which can satisfactorily be peeled from a light-hardened resin layer and a manufacturing method of an optical multilayer recording medium with satisfactory productivity by using such a stamper.
The manufacturing method of the optical multilayer recording medium has a process for laminating the uncured light-curing resin layer and the transparent stamper composed of an amorphous polyolefin resin on a substrate in this order, a process for curing an uncured resin with light transmitting the transparent stamper and a process for removing the transparent stamper. Thus, the transparent stamper can easily be peeled off from the cured resin layer.
