    摘要: A film is bonded to a substrate by applying a layer of adhesive to the film to be bonded, contacting the film with a substrate and subjecting the adhesive to high energy radiation either before, during or after the film and substrate are contacted. The adhesive layer is from 0.5 to 20 .mu.m thick. The adhesive employed is a mixture of at least one polyisocyanate and at least one compound containing both a (meth)acryloyl group and a hydroxyl group in which the equivalent ratio of hydroxyl to isocyanate groups is from 0.8 to 1 to 1.3 to 1. The substrate to which the film is to be bonded may also be a film. Composites formed in accordance with the present invention are characterized by high initial bond strengths.

    摘要: The present invention relates to polyisocyanate compositions containing reversibly blocked catalysts for the isocyanate addition reaction, characterized in that they contain(a) at least one organic polyisocyanate,(b) at least one addition product dissolved or dispersed in the polyisocyanate compositions, of a sulfonyl isocyanate with a tertiary amine and/or with a catalyst having a tin(II)- or tin(IV)-carboxylate structure as the reversibly blocked catalyst.The present invention also relates to a process for producing these polyisocyanate compositions and to the use of new polyisocyanate compositions as reactants for compounds containing isocyanate-reactive groups for the production of isocyanate addition products such as polyurethane plastics using a one-component or two-component principle. The present invention finally relates to the latent polyurethane catalysts prepared from a sulfonyl isocyanate and a tin(II)- or tin(IV)-carboxylate.
