PURPOSE:To pretreat an adherend i.e., a member made of a difficultly bondable material such as a polyolefin so as to make it easily bondable with a common adhesive. CONSTITUTION:The pretreatment process comprises applying a photopolymerization initiator which can develop a dehydrogenation property when irradiated with ultraviolet rays to the bonded surface of an adherend, irradiating the surface with ultraviolet rays and applying a primer containing an isocyanate component thereto. |
