<p>A layer of a liquid composition containing an epoxide resin as the sole photopolymerizable component, a heat-activated curing agent for epoxide resins, and preferably a photopolymerization catalyst, is exposed to actinic radiation until the layer solidifies to form an essentially solid, continuous film due to photopolymerization of the epoxide resin through epoxide groups, the resin remaining, however, still thermosettable by virtue of residual epoxide groups. The film so formed is sandwiched between, and in contact with, surfaces to be bonded together, and the assembly is heated to cure the epoxide resin.</p> |
