PROBLEM TO BE SOLVED: To obtain a cationic polymerizing and ultraviolet-curing adhesive composition capable of obtaining a uniform and fast cured film wherein the adhesive is applied for bonding two substrates especially optically non- transmitting disk substrates for DVD or the like. SOLUTION: This ultraviolet curing-type laminating adhesive composition is obtained by including (A) an epoxy resin, (B) a photo cationic polymerization initiator and (C) a photo radical generator having absorption maximum in longer wavelength region than the maximum absorption wavelength of the initiator (B). |
