Abstract: The present invention relates to the use for coating three-dimensionally structured surfaces and/or moldings of melamine resin sheets and/or films produced from cellulosic fiber materials post- or pre- and post-impregnated with an aqueous solution comprising (i) a melamine-formaldehyde condensate, (ii) an etherified melamine-formaldehyde condensate, and (iii) a polymer dispersion.

Abstract: The present invention relates to a process for the production of laminated substrates having a three-dimensionally structured surface, wherein a decorative paper which comprises from 5 to 90% by weight, based on the total fiber content, of fibers of synthetic polymers is impregnated with a crosslinkable aminoplast resin, applied to the substrate and three-dimensionally shaped. Furthermore, the invention relates to aminoplast resin sheets or films, and the use of a modified decorative paper for the production of aminoplast resin sheets or films for 3D lamination.
