Abstract: 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.

Abstract: A process for producing colored, resin-impregnated paper sheets with a three-dimensional surface structure. A paper sheet is printed with a pattern using aqueous printing ink. The printing ink which is printed on regions which are to have a thinner lacquer film contains a lacquer repelling material. After the printed sheet is dried, it is lacquered with an aqueous lacquer having a viscosity of 15 to 40 seconds in an AK-4 beaker. The lacquer includes as binder a mixture comprising(A) a mixture of urea and/or melamine resin, dissolved in water, and an aqueous acid as hardener, which cures in less than 100 seconds at a temperature above 100.degree. C. after the aqueous resin solution is mixed with the acid, and(B) a binder selected from the group consisting of(a) water-dilutable polyester resin,(b) acrylate resin, and(c) ethoxylated derivative of glycerin,there being 10 to 250 parts by weight of solids of binder (B) for every 100 parts by weight of solids of binder (A).

Abstract: The invention provides a multi-layer board of from 0.3 to 5.0 mm. thick, comprising an upper layer of a finishing coat which is a varnish hardened by means of electron radiation, one or more carrier films and, optionally, a backing film.
