Method for producing a decorative sheet having an adhesive layer on its back surface

A decorative sheet to be applied to a substrate, comprising:

• a resin-impregnated paper having first and second opposed major surfaces, and a printed pattern formed on said first major surface thereof;
• and
• an adhesive layer formed on said second major surface of said paper, said adhesive layer comprising an inorganic filler and a dimer acid based polyamide resin, said adhesive layer being maintained in a non-adhesive state until said sheet is to be applied to a substrate;
• wherein said decorative sheet is formed by:
• (i) coating said second major surface of said paper with a thermoplastic resin liquid comprising said inorganic filler, said dimer acid based polyamide resin, and a solvent mixture selected from (a) toluene and isopropanol, and (b) toluene, xylene and isopropanol, said resin liquid being in a liquid state at room temperature;
• and
• (ii) drying and cooling the coated resin liquid to thereby form said adhesive layer in a solidified, non-adhesive state on said second major surface of said paper.
