Abstract
Abstract Method of dye absorption into the surface of plastics is accomplished by placing polyethylene film between a dye transfer paper and a sheet of plastic and applying pressure and heat thereto. The heat applied is sufficient to soften the film and to sublime the dyes through the film to the plastic material. The dyes are absorbed into the surface of the plastic with the design intact. The materials are then cooled and separated and a decorated plastic with wear-proof design is obtained.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
110 words
A METHOD FOR TRANSFERRING PATTERNS TO DYE RECEPTOR THERMOPLASTIC NON-POROUS SHEET, COMPRISING INTERPOSING A POLYOLEFIN SHEETS BETWEEN A DYE TRANSFER SHEET CONTAINING DISPERSED DYES AND SAID DYE RECEPTOR THERMOPLASTIC SHEET; PRESSING SAID SHEET TOGETHER TO OBTAIN CLOSE CONTACT THEREBETWEEN; HEATING THE PRESSED SHEETS TO A SUBLIMATION TEMPERATURE FOR THE DYES AND TO A SOFTENING POINT OF SAID POLYOLEFIN SHEET, MAINTAINING SAID SHEETS AT SAID TEMPERATURES UNTIL A SUBSTANTIAL PORTION OF SAID DYES HAVE SUBLIMED AND TRANSFERRED THROUGH SAID POLYOLEFIN SHEET TO SAID DYE RECEPTOR SHEET; COOLING SAID SHEETS BELOW THE SOFTENING TEMPERATURE OF THE POLYOLEFIN SHEET AND DYE RECEPTOR SHEE5 AND SEPARATING SAID DYE RECEPTOR SHEET FROM THE PRESSED MATERIALS.
Claim 2
Independent Claim
110 words
A METHOD FOR TRANSFERRING PATTERNS TO DYE RECEPTOR THERMOPLASTIC NON-POROUS SHEET, COMPRISING INTERPOSING A POLYOLEFIN SHEETS BETWEEN A DYE TRANSFER SHEET CONTAINING DISPERSED DYES AND SAID DYE RECEPTOR THERMOPLASTIC SHEET; PRESSING SAID SHEET TOGETHER TO OBTAIN CLOSE CONTACT THEREBETWEEN; HEATING THE PRESSED SHEETS TO A SUBLIMATION TEMPERATURE FOR THE DYES AND TO A SOFTENING POINT OF SAID POLYOLEFIN SHEET, MAINTAINING SAID SHEETS AT SAID TEMPERATURES UNTIL A SUBSTANTIAL PORTION OF SAID DYES HAVE SUBLIMED AND TRANSFERRED THROUGH SAID POLYOLEFIN SHEET TO SAID DYE RECEPTOR SHEET; COOLING SAID SHEETS BELOW THE SOFTENING TEMPERATURE OF THE POLYOLEFIN SHEET AND DYE RECEPTOR SHEE5 AND SEPARATING SAID DYE RECEPTOR SHEET FROM THE PRESSED MATERIALS.
Claim 3
Dependent Claim
12 words
The method of claim 1, wherein said sheets pressed between heated platens.
Claim 4
Dependent Claim
16 words
The method of claim 1 wherein said polyolefin is first coated upon said dye transfer sheet.
Claim 5
Dependent Claim
39 words
The method of claim 1 wherein said dye transfer sheet and said polyolefin sheet are pressed together with a thermoplastic sheet extrudate after the latter issues from a die and the sheets are pressed in the nip of rollers.
Claim 6
Dependent Claim
15 words
The method of claim 1 wherein said sheets are pressed between 1 to 2,000 psi.
Claim 7
Dependent Claim
13 words
The method of claim 1 wherein said sheets are heated over 230* F.
Claim 8
Dependent Claim
13 words
The method of claim 1 wherein polyethylene is employed as said polyolefin sheet.
Claim 9
Independent Claim
149 words
A method for dye transfer and lamination of sheets comprising, interposing a polyolefin sheet between a dye transfer sheet containing dispersed dyes and a dye receptor thermoplastic non-porous sheet placing a laminating sheet adjacent said dye receptor sheet, on the reverse side thereof; pressing all of said sheets together to obtain a close contact therebetween at a laminate pressure for said dye receptor sheet and said laminate sheet; heating the pressed sheets to a sufficient temperature for sublimation of the dyes and for fusion of the dye receptor sheet and said laminating sheet; maintaining said heat and pressure until a substantial portion of said dyes have transferred to said dye receptor sheet and said lamination has occurred; cooling the pressed materials to complete said lamination; releasing said pressure and separating the resulting laminate of dye receptor sheet and laminated sheet from the dye transfer sheet and the polyolefin sheet.
Claim 10
Independent Claim
149 words
A method for dye transfer and lamination of sheets comprising, interposing a polyolefin sheet between a dye transfer sheet containing dispersed dyes and a dye receptor thermoplastic non-porous sheet placing a laminating sheet adjacent said dye receptor sheet, on the reverse side thereof; pressing all of said sheets together to obtain a close contact therebetween at a laminate pressure for said dye receptor sheet and said laminate sheet; heating the pressed sheets to a sufficient temperature for sublimation of the dyes and for fusion of the dye receptor sheet and said laminating sheet; maintaining said heat and pressure until a substantial portion of said dyes have transferred to said dye receptor sheet and said lamination has occurred; cooling the pressed materials to complete said lamination; releasing said pressure and separating the resulting laminate of dye receptor sheet and laminated sheet from the dye transfer sheet and the polyolefin sheet.
Claim 11
Dependent Claim
16 words
The method of claim 8 wherein said polyolefin is first coated upon said dye transfer sheet.
Claim 12
Dependent Claim
38 words
The method of claim 8 wherein said dye receptor sheet issues as an extrudate between said laminating sheet and said polyolefin sheet and said dye transfer sheet and all materials are pressed together in the nip of rollers.
Claim 13
Dependent Claim
15 words
The method of claim 8, wherein said sheet are pressed between 1 to 2,000 psi.
Claim 14
Dependent Claim
13 words
The method of claim 8 wherein said sheet are heated over 230* F.
