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. The surface of the decorative laminate sheet consists essentially of resin particulates which melted and flowed in the forming method to form a surface layer.
Claims2
A method for providing a decorative laminate sheet from a decorative facing sheet suitable for pressing, said laminate sheet having a surface coating, the method comprising:
- coating a decorative sheet with a liquid impregnating resin coating mixture;
- depositing surface coating resin particulates that melt and flow under heat and pressure onto the impregnating resin-coated decorative sheet in an amount of from about 0.5 pounds to about 10 pounds dry weight per ream of the decorative sheet, wherein the resin of said surface coating resin particulates is dissimilar to the resin of said impregnating resin;
- drying the coated decorative sheet having resin particulates thereon to form a coated decorative sheet;
- and
- pressing and heating the dried, coated decorative sheet so that the resin particulates melt and flow to form a decorative laminate sheet having a surface coating consisting essentially of the surface coating resin particulates.
