METHOD FOR CURING PHOTOCURABLE ADHESIVE AND LIGHT IRRADIATOR FOR CURING ADHESIVE

摘要

PROBLEM TO BE SOLVED: To provide a method for curing a photocurable adhesive, by which a high energy efficiency and a sufficiently large adhesive strength are obtained, and to provide a light irradiator for curing an adhesive. SOLUTION: This method for curing the photocurable adhesive is characterized by irradiating a photocurable adhesive comprising a photopolymerizable resin containing a photopolymerization initiator having a light-absorbing peak wavelength of 375 nm with a laser beam oscillated from a semiconductor laser and having a main oscillation wavelength in a wavelength range of 373 to 378 nm to cure the photocurable adhesive. The light irradiator for curing the adhesive is characterized by having a light source for radiating a curing light to be irradiated on a photocurable adhesive comprising a photopolymerizable resin containing a photopolymerization initiator having a light-absorbing peak wavelength of 375 nm, wherein the light source is a semiconductor laser for oscillating laser beam having a main oscillation wavelength in a wavelength range of 373 to 378 nm.
