PASTING TOGETHER, DEVICE THEREFOR, AND PRODUCTION OF LIGHT DISK

摘要

PROBLEM TO BE SOLVED: To provide a method for pasting together suppressing involving in air bobbles with slight adhesion unevenness even in using a cationic ultraviolet- curable resin. SOLUTION: In this method, a cationic ultraviolet-curable composition 5 is dropped from a dispenser 1 and ultraviolet rays are irradiated from an ultraviolet rays irradiating means 2 before the light attains a disk substrate 4. The cationic ultraviolet-curable composition 5 is dropped on the disk substrate 4 in a ring-like and the cationic ultraviolet-curable composition 5 is extended by superposing to another disk substrate.
