PURPOSE:To accomplish bonding with high initial adhesive force enabling adhesion to be attained under non-press condition, suitable for base material with curved surface, applicable, as adherend, to metals, by coating specific adhesive on a base material followed by light irradiation and laminating adherend followed by curing. CONSTITUTION:A two-step reaction-type adhesive (pref. with a glass transition temperature after light irradiation <=ca.40 deg.C) comprising (A) a non- photopolymerizable epoxy resin or isocyanate compound, (B) a curing agent therefor and (C) a second compound having in one molecule at least one photopolymerizable vinyl group is coated on a base material followed by light irradiation on the coated surface throughout to develop tackiness, then laminating an adherend during exhibiting the tackiness followed by curing, thus accomplishing the objective bonding.
