ULTRAVIOLET ACTIVATING ADHESIVE FILM

摘要

PROBLEM TO BE SOLVED: To prolong the serviceable life of an ultraviolet activating adhesive film to allow it to maintain high adhesion properties. SOLUTION: An ultraviolet activating adhesive composition comprising an epoxy resin, an ultraviolet activating cationic polymerization catalyst, and a cationic polymerization inhibitor is coated on a separator, dried, and then exposed to an atmosphere having a steam density of 7μg/cm<3> to less than saturated stream to obtain the ultraviolet activating adhesive film.
