Abstract: It is possible to manufacture articles out of thermoplastic materials and to metallize the articles at their surface. In this way one can manufacture reflectors and similar articles. Most thermoplastic materials require extra processing steps prior to the metallization like application of primers, chemical etching and the like.The invention is based on the discovery that a certain type of materials can be metallized without any extra processing steps. The materials involved are polyestercarbonates or blends of polyestercarbonates and polycarbonate. This is quite surprising since polycarbonates can not be metallized in good quality without extra processing steps prior to the metallization step.

Abstract: The present invention relates to multilayer wood veneer composite laminates, the outermost layer of which is a natural wood veneer, and the substrate of which is a plurality of layers of cellulose-containing plastic sheets, and a method to make the composite laminate. The composite laminate according to the present has the look, feel, heft, and sound when struck of natural wood. The method has a very short cycle time, which increases the utilization of capital equipment, and includes the steps of laying-up the substrate layers, pre-heating the substrate layers, applying adhesive to the bottom surface of the outer layer or layers, laying-up the outer layer(s) on the pre-heated substrate layers, and cold pressing the layers in a compression die. The laminate is then de-molded. If a metal die is utilized, the laminate will be cool upon de-molding.

Abstract: An improved oxygen barrier layer for coating a substrate, such as a polymeric film. The oxygen barrier is a layer of cross-linked polyvinyl alcohol and glyoxal, which exhibits improved barrier characteristics to the transmission of oxygen. The oxygen barrier is produced by coating a solution of polyvinyl alcohol, glyoxal and tensoactive agent onto at least one side of a substrate adapted for receipt of such solution. The polyvinyl alcohol is thereafter cross-linked in the absence of a catalyst to provide the oxygen barrier.
