  • Patent number: 4005239
    Abstract: A decorative laminated panel and a process for making said panel comprising (1) coating the back most flat surface of a laminate with a uniform layer of a solution of an elastomeric adhesive and removing excess solvent, (2) coating one face of a compressible, flexible, closed; cell polypropylene plastic foam sheet with a solution of an elastomeric adhesive and removing solvent, (3) superimposing the decorative laminate over said polypropylene plastic foam sheet with the adhesively coated side of the laminate facing the adhesively coated side of the polypropylene foam, (4) applying pressure to the flat surface of the laminate and plastic foam so as to form a unitary panel. To bond said decorative laminated panel to a substrate one can apply an elastomeric adhesive to the back of the panel and to a rigid substrate and installing the panel by pressing against the rigid substrate to which the panel is to be attached.
