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

The method of decorating sheeting which comprises the steps of:

• A. providing a substrate comprising paper,
• B. providing a coating of thermoplastic material on a surface of said substrate forming a multilayer sheeting, said thermoplastic material selected from the group consisting of polyethylene, styrene acrylate, styrene butadiene and polyvinylacetate, said thermoplastic material further containing a hydroxylated polysiloxane.
• C. heating the coating before embossing, to a temperature above its softening temperature,
• D. embossing said sheeting by embossing the thermoplastic coating on said substrate with a diffraction or holographic pattern, said embossing achieved with an embossing roller which comes into pressure contact with said coating, said embossing roller being at a temperature below the softening temperature of the thermoplastic coating during embossing, embossing being carried out at speeds between about 100 to 800 ft/min of said sheeting, and wherein the depth of surface roughness of said substrate before embossing exceeds the depth of the embossment.

The method of decorating sheeting which comprises the steps of:

• A. providing a substrate selected from the group consisting of paper and heat resistant plastic film,
• B. providing a coating of thermoplastic material on a surface of said substrate forming a multilayer sheeting, said thermoplastic material containing a release agent;
• C. heating the coating before embossing, to a temperature above its softening temperature and in a range between about 250.degree. F. and 450.degree. F.,
• D. embossing said sheeting by embossing the thermoplastic coating on said substrate with a diffraction or holographic pattern, said embossing achieved with an embossing roller which comes into pressure contact with said coating, said embossing roller being at a temperature below the softening temperature of the thermoplastic coating during embossing, said embossing roller being at a temperature between about 100.degree. F. to 200.degree. F., said embossing being carried out at speeds between about 100 to 800 ft/min of said sheeting.
