Method for producing coated substrates

A process for the production of a partly or a completely laminated substrate comprising 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 a synthetic polymer is impregnated with a crosslinkable aminoplast resin, applied to the substrate and three-dimensionally shaped.

An aminoplast resin sheet or film comprising decorative paper impregnated with a resin mixture comprising:

• (i) from 20 to 90% by weight of one or more unetherified melamine/formaldehyde condensates,
• (ii) from 0 to 80% by weight of one or more etherified melamine/formaldehyde condensates,
• (iii) from 10 to 80% by weight of one or more polymer despersions, the amounts of the components (i), (ii), and (iii) summing to 100% by weight and being based on the liquid resin mixture, and comprising from 5 to 90% by weight, based on the total fiber content, of fibers of polyamide, polyimide, polyurethanes, polypropylene, polyethylene, polyester, polyacrylonitrile or polyvinyl alcohol, or mixtures thereof.

A method for the lamination of substrates having three-dimensionally structured surfaces, and/or moldings comprising utilizing an aminoplast resin or film comprising a decorative paper which comprises from 5 to 90% by weight, based on the total fiber content, of fibers of synthetic polymers.
