Laminate comprises at least a substrate SI (a); at least a hot-melt adhesive (b) comprising at least a polyurethane polymer containing isocyanate groups and is solid at room temperature and at least an aldimine; and at least a substrate S2 (c); where (a) and/or (c) are a plasticizer containing plastic, (a) and/or (c) are pretreated with a primer and (a) is joined to (c) via (b). Independent claims are included for: (1) a coated polymeric film obtained by applying a hot-melt adhesive in a melted state to a film of a plasticizer-containing plastic, preferably plasticized polyvinyl chloride film; and (2) a process for the adhesive bonding of a plasticizer-containing plastic, comprising either (i) melting the hot-melt adhesive, (ii) applying the melted hot-melt adhesive to (a) and (iii) contacting the surface of (c) with the hotmelt adhesive within its open time, or (ia) melting a hot-melt adhesive, (iia) applying the melted hot-melt adhesive to (a), (iiia) cooling the hot-melt adhesive t o room temperature, (iva) melting the hot-melt adhesive located on (a) and (va) contacting the surface of (c) with the hotmelt adhesive, or (ib) melting a hot-melt adhesive and (iib); applying the melted hot-melt adhesive into a gap confined laterally substantially by the surfaces of (a) and (c), where at least one (a) or (c) being a plasticizer-containing plastic and (a) being composed of the same material as or a different material to (c) and the hot-melt adhesive comprising at least one aldimine and at least one polyurethane polymer containing isocyanate groups and is solid at room temperature. |
