METHOD FOR PEELING PRESSURE-SENSITIVE ADHESIVE SHEET BY USING LASER BEAM

摘要

PROBLEM TO BE SOLVED: To provide a method for making a plate effectively reusable by peeling a pressure sensitive strongly adhesive sheet of a composite plate, obtained by adhering the surface of plates each other with the sheet, with a simple device without damaging the plate and without remaining the sheet on the plate. SOLUTION: The method for peeling the pressure sensitive adhesive sheet from a composite plate which is obtained by oppositely adhering a pair of plates, at least one of which is a specific wavelength laser beam-transmissive plate, comprises irradiating the specific wavelength laser beam on the laser beam-transmissive plate surface of the composite plate.
