VERFAHREN ZUR HERSTELLUNG VON FARBIGEN MELAMINHARZHALTIGEN DEKORPAPIERFOLIEN MIT EINER DREIDIMENSIONALEN OBERFLAECHENSTRUKTUR

摘要

A process for the production of colored films of paper impregnated with synthetic resin which contain melamine resin and have a three-dimensional surface structure, by printing the paper films with a colored pattern using an aqueous protein-based printing ink and lacquering thereover. The color which is printed in the regions in which the lacquer layer is to be thinner than in the other regions contains a lacquer repellent, and the printed and dried paper film is impregnated with an aqueous impregnation of a melamine resin from the unprinted side, with the formation of a one-sided excess of resin, and is dried. The printed and impregnated film is coated on the printed side with an aqueous lacquer based on melamine resins, and the lacquered film is hardened at elevated temperature without applying pressure. A laminate is produced by joining the unprinted side of the hardened film to a substrate such as chipboard.
