<p>The resin composition comprises an anti-abrasion powder filler, at least one fibrous filler and at least one thickener. Impregnating aminoplast resin comprises charging with at least one mineral anti-abrasion powder and contains at least one fibrous filler and at least one thickening agent soluble or dispersible in the colloidal state in the resin, with the nature and quantity of filler and thickener selected so as to produce a modified system of aminoplast resin plus anti-abrasive mineral filler with pseudo-plastic or essentially pseudo-plastic rheological properties. The resin preferably also contains at least one additive selected from wetting agents, surfactants, adhesion promoters, liquid or solid lubricants and antistatic agents, and at least one latent hardener, in an amount 0.1-1 wt.% per weight of base resin, selected from salts of mineral or organic acids neutralized with bases. An Independent claim is also included for a layered coating obtained by hot pressing onto a support of opaque paper with printed decorative motive (decorative paper) A which can be coated with at least one transparent protection paper (overlay paper) B, with at least one of A or B being coated, if necessary twice, with resin as claimed, and A optionally pre-coated with resin containing hardener, with second coat of resin as claimed applied when partially dried; while B is primary impregnated with aminoplast impregnating resin as claimed.</p> |
