Abstract

The invention concerns laminates comprising a filled polyolefin layer and a thermoplastic decorative layer, a process for the preparation of these laminates and the use of the laminates for the production of moldings. Between the outer, polyolefin, layer and the decorative layer the novel laminates contain an adhesion-providing layer comprising a fiber-blend web or fabric containing two or more fusible types of fibers, of which one type welds to one of the outer layers to give a good bond, and another type welds to the other outer layer. If one outer layer of the laminate is a polyolefin, one of the fibers of the web can be polypropylene, and if the other outer layer is PVC, one of the fibers can be PVC. The preferred embodiment is a laminate of polypropylene and PVC, with the web or fabric consisting of polypropylene fibers and PVC fibers.
