Abstract
Abstract A method for decoration of paper or plastic sheeting and other substrates, involving a novel technique for coating and embossing the substrate. The paper or plastic sheeting is supplied with a coating of thermosensitive material, as by extrusion. The coated sheet is heated to adequately soften the coating, such as by use of a heated cylinder, and remote heat sources such as infrared heaters. The softened sheet surface is then decorated using an embossing member, to provide a diffraction pattern or hologram. Use of an embossment pattern of lesser depth than the surface roughness of the sheet before embossing provides attractive decorative patterns.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
101 words
The method of high speed decoration of sheeting which comprises the steps of: (a) providing a paper substrate; (b) providing a coating of thermoplastic material containing a release agent on a surface of said paper substrate; (c) heating the coating to a temperature above its softening temperature; and (d) contacting the heated thermoplastic coating with an embossing member under rolling pressure contact at a speed of greater than 100 feet/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.
Claim 2
Independent Claim
101 words
The method of high speed decoration of sheeting which comprises the steps of: (a) providing a paper substrate; (b) providing a coating of thermoplastic material containing a release agent on a surface of said paper substrate; (c) heating the coating to a temperature above its softening temperature; and (d) contacting the heated thermoplastic coating with an embossing member under rolling pressure contact at a speed of greater than 100 feet/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.
Claim 3
Dependent Claim
20 words
The method of claim 1 wherein the roughness of the paper substrate before embossing exceeds the depth of the embossment.
Claim 4
Dependent Claim
25 words
The method of claim 2 wherein the roughness of said substrate exceeds one micron and the depth of said embossment is less than one micron.
Claim 5
Dependent Claim
38 words
The method of claim 2 wherein the depth of surface roughness of said coating is greater than 0.7 microns, and the depth of the embossment is less than the depth of surface roughness of the coating before embossing.
Claim 6
Dependent Claim
20 words
The method of claim 1 wherein the embossing member is selected from the group consisting of rollers, belts and webs.
Claim 7
Dependent Claim
23 words
The method of claim 1 wherein the embossing member during embossing is at a temperature below the self-adhesive temperature of the thermoplastic coating.
Claim 8
Dependent Claim
56 words
The method of claim 1 wherein the embossing is accomplished by passing said sheeting between an embossing roller and a nip roller, and wherein the force applied between the embossing roller and nip roller during embossing is in the range between 100 to 500 pounds per lineal inch along the length of contact of said rollers.
Claim 9
Dependent Claim
23 words
The method of claim 1 wherein the thermoplastic coating before embossing is at a temperature in the range 250° F. to 350° F.
Claim 10
Dependent Claim
23 words
The method of claim 1 wherein the embossing member during embossing is at a temperature in the range 100° F. to 200° F.
Claim 11
Dependent Claim
25 words
A method as in claim 1 wherein the heating of said coating before embossing is accomplished with at least one heater not contacting the coating.
Claim 12
Dependent Claim
14 words
The method of claim 1 further including the step of metallizing the embossed coating.
Claim 13
Dependent Claim
14 words
The method of claim 1 wherein the release agent comprises a polysiloxane release agent.
Claim 14
Dependent Claim
26 words
The method of claim 1 further comprising the step of filling in said embossed pattern at least in part with an ink or lacquer coating material.
Claim 15
Dependent Claim
36 words
The method of claim 1 wherein said thermoplastic coating has opposed surfaces of which an outer surface is embossed and an underlying surface is metallized; thereby to provide an embossed metallized member at relatively high speeds.
Claim 16
Dependent Claim
15 words
The method of claim 1 wherein the thermoplastic coating contains an opaque or tinted material.
Claim 17
Independent Claim
124 words
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.
Claim 18
Independent Claim
124 words
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.
