Loss of the gradually adhesive property when welding the plasticizer - containing plastic as the reactive polyurethane hot-melt adhesive is removed or reduced. A laminate(1) includes is one or more substrate S1(3), one or more hot-melt adhesive K(5) and one or more substrate S2(4). The substrate S2 and/or the substrate S1 are(is) the plasticizer-containing plastic. If necessary, the substrate S2 and/or the substrate S1 are(is) preliminarily processed by the primer, the substrate S1 is combined through the hot-melt adhesive K in the substrate S2. |
