  • Decorative paper and impregnated paper
    Patent number: 5447777
    Abstract: The present invention relates to a decorative paper with high abrasion resistance. The present invention provides a thin film containing a thermosetting resin hardener on a sheet of decorative paper. The decorative paper is then impregnated with thermosetting resin. In the press process to manufacture a decorative board, since the thermosetting resin around the printed layer hardens faster than the resin of the raw paper, the resin on the surface is not absorbed and forms a thick hardened film. This provides a decorative board of excellent surface properties including high abrasion resistance.
