Method for bonding members, and disc manufacturing method and device

A method for manufacturing discs by bonding two disc substrates (1a, 1b) using a cationic polymerization type ultraviolet curable composition (S) as an adhesive to produce a disc (1). The method includes the steps of: applying the cationic polymerization type ultraviolet curable composition onto a p...

Zusammenfassung:	A method for manufacturing discs by bonding two disc substrates (1a, 1b) using a cationic polymerization type ultraviolet curable composition (S) as an adhesive to produce a disc (1). The method includes the steps of: applying the cationic polymerization type ultraviolet curable composition onto a part of an adhering surface of one of the two disc substrates; radiating ultraviolet light onto the cationic polymerization type ultraviolet curable composition; bonding the disc substrate to the other disc substrate via the cationic polymerization type ultraviolet curable composition which has been irradiated by the ultraviolet light; and spreading the cationic polymerization type ultraviolet curable composition which is present between the two disc substrates.
