ABSTRACT:
Adhesion between an adhesive of the class of polymerizable liquid ethylenically unsaturated compounds containing a single vinyl group and solid polyester-containing plastic materials is improved by treating the substrate with a primer composition comprising an aromatic polyisocyanate and an amino resin and moisture-curing the polyisocyanate compound prior to application of the adhesive. The adhesive-joined assemblies are cured in a first stage at room temperature and, in a second stage, are post-baked at 100.degree. to 150.degree. C. to complete cure of the adhesive and the primer.
