Title:
RECORDING DISC
Document Type and Number:
Japanese Patent JPS6074137
Kind Code:
A
Abstract:

PURPOSE: To improve the adhesion between a base and a resin film curable by UV light by using a laminated resin sheet for the base.

CONSTITUTION: The resin curable by UV light to be used in this invention may be the resins used thus far in this field. a laminated resin sheet to be used for the base is the sheet-like molding formed by laminating a requred number of cloth or paper impregnated with various resins, inserting the entire part between specular surface plates formed of a metal and pressurizing the same under heating and is representatively such a sheet as regulated by JIS K 6912. For example, a paper-phenolic resin and paper-epoxy resin may be enumerated and particularly when heat resistance is required, the laminated sheet using a polyimide resin and polyester resin as the resin is preferred. The manufacture of the recording disc is accomplished by coating a surface treating agent, if necessary, on the surface of the laminated resin sheet, which is a base, and coating and forming the resin film curable by UV light thereon. A stamper is pressed to the surface of the resin film and UV light is irradiated to cure said resin.
