Abstract

A decorative laminate surface layer composition is prepared by selectively applying dissimilar thermoset or thermoplastic polymers to a decorative laminate facing sheet to achieve a brillant visual or pearlescent appearance.

Claims

1. A coated transfer sheet for use with a decorative facing sheet to provide a decorative laminate sheet suitable for pressing, comprising:

(a) a transfer release sheet having two exterior surfaces; and

(b) a coating applied to one surface of the transfer release sheet, said coating comprising a surface coating resin that melts and flows under heat and pressure during lamination to impart one or more of the following properties;

enhanced wearbility, chemical, thermal, or ultra-violet radiation resistance or abrasion resistance.

2. A transfer sheet in accordance with claim 1, wherein the surface coating resin is a polymer selected from the group consisting essentially of polyester, polyurethane, epoxy, polyvinyl chloride, acrylic, and mixture of two or more or the foregoing.

3. A transfer sheet in accordance with claim 1 wherein said coating further includes a mixture of an abrasion resistant hard mineral having a particle size of between about 1-200 microns in a concentration sufficient to provide abrasion resistance without interfering with visiblity.

4. A transfer sheet in accordance with claim 1, wherein said abrasion resistant hard particles are selected from the group consisting essentially of alumina, silica, zirconium, oxide, cerium oxide, glass beads, diamond dust, and mixtures of two or more of the foregoing.

5. A laminate produced from the transfer sheet prepared in accordance with claims 1.
