Patent number: 5229217Abstract: The invention concerns the production of a decorative high-pressure laminate with a surface layer (3) on the surface of which an adhesive primer layer (4) of polyvinyl butyral is applied. The adhesive primer layer (4) enables a lacquer coating to be applied subsequently, so that a lacquer layer optimally suited to the particular application for which the laminate is eventually used can be chosen. The adhesive primer layer (4) can be applied by impregnating a web of paper with melamine resin, dusting the impregnated web with polyvinyl butyral powder while the resin is still wet and then drying. Another way of producing the coat is to apply polyvinyl butyral in alcoholic solution to a web of paper which has been impregnated with melamine resin and dried, and subsequently drying.Type: GrantFiled: July 25, 1991Date of Patent: July 20, 1993Assignee: Resopal GmbHInventor: Herbert Holzer
