Method for embossing a coated sheet with a diffraction or holographic pattern

The method of high speed decoration or sheeting which comprises the steps of:

• (a) providing a paper substrate;
• (b) providing a coating of thermoplastic material on a surface of said paper substrate, said thermoplastic material including a release agent;
• (c) heating the coating to a temperature above its softening temperature;
• and
• (d) contacting the heated thermoplastic coating with an embossing member in rolling pressure contact at a speed between about 100 to 800 ft./minute to emboss the coating with a diffraction or holographic decorative pattern, wherein the embossing member is at a temperature below the softening temperature of said coating before and during said embossing, and wherein the depth of surface roughness of said paper substrate before embossing exceeds the depth of the embossment.
