<p>A laminate or a laminated article with integrated raised zones having the appearance of buttons, borders, surrounds, folds or the like is specified. A process for producing such a laminated article is also specified. The laminated article consists of a textile or vinyl synthetic resin cover layer, a foam intermediate layer and a layer of substrate material, for example a polyamide. A shaped article having the desired shape for the raised zone is inserted between the foam layer and the cover material layer. Anhydric polyurethane foam-forming materials are applied in liquid form onto the foam layer, the contact surface of the cover material and the contact surface of the substrate material. Before the lamination, the layers are placed on a mould, the shaped articles being arranged directly above those mould projections which follow the contours of the mould projections. Moisture is introduced into the foamable material and a heated press is caused to act on the substrate material, the layers lying one above the other being pressed downwards against the mould. The press force with simultaneous heat supply causes a foaming reaction of the foamable material, leading to a foam adhesive layer which substantially adhesively bonds the cover material to the substrate material in the zone surrounding the shaped articles. The binder layer also bonds the cover material and the substrate material to the other surfaces of the foam layer.</p> |
