Abstract
Abstract A decorative laminate and method of transferring designs onto articles. The laminate is formed of a transfer substrate affixed to a support member. The transfer substrate is composed of a protective layer, an ink layer, and a nonwax-based adhesive/release layer. The adhesive/release layer is in direct contact with the support member and use of a wax layer intermediate the adhesive/release layer and the support is excluded. Optionally, a barrier layer is provided between the adhesive/release layer and the ink layer. In many applications the protective coating layer may be omitted. The laminate is applied to an article using a heated silicone rubber transfer pad to which the transfer substrate adheres during the transfer process.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
137 words
A process for transferring a decorative laminate from a support to an article, comprising the steps: heating the laminate, which is comprised of a nonwax-based adhesive/release layer in contact with the support, and a design layer, to a first temperature above the melting point of said adhesive/release layer, said laminate not having a wax-based release layer intermediate said adhesive/release layer and the support; heating the surface of an elastomeric member to a second temperature below said first temperature; contacting the laminate under pressure with the heated elastomeric member so that the laminate adheres to the elastomeric member and separates from the support upon withdrawal of said elastomeric member; impressing the laminate against the article to bond the adhesive/release layer thereto; and withdrawing the elastomeric member from the article, whereupon the laminate remains permanently adhered to the article.
Claim 2
Dependent Claim
137 words
A process for transferring a decorative laminate from a support to an article, comprising the steps: heating the laminate, which is comprised of a nonwax-based adhesive/release layer in contact with the support, and a design layer, to a first temperature above the melting point of said adhesive/release layer, said laminate not having a wax-based release layer intermediate said adhesive/release layer and the support; heating the surface of an elastomeric member to a second temperature below said first temperature; contacting the laminate under pressure with the heated elastomeric member so that the laminate adheres to the elastomeric member and separates from the support upon withdrawal of said elastomeric member; impressing the laminate against the article to bond the adhesive/release layer thereto; and withdrawing the elastomeric member from the article, whereupon the laminate remains permanently adhered to the article.
Claim 3
Dependent Claim
20 words
A process as defined in claim 1 wherein the transferred laminate on the article is not subjected subsequently to firing.
Claim 4
Dependent Claim
23 words
A process as defined in claim 1 wherein the adhesive/release layer comprises a polymerization product of a diamine with a dimerized fatty acid.
Claim 5
Dependent Claim
19 words
A process as defined in claim 1 wherein the laminate further comprises a protective layer over said design layer.
Claim 6
Dependent Claim
23 words
A process as defined in claim 1 wherein the laminate further comprises a barrier layer intermediate the adhesive/release layer and the design layer.
Claim 7
Dependent Claim
18 words
A process as defined in claim 1 wherein the first temperature is in the range 330° F.-420° F.
Claim 8
Dependent Claim
19 words
A process as defined in claim 1 wherein the second temperature is in the range from 150° F.-300° F.
Claim 9
Dependent Claim
19 words
A process as defined in claim 1 wherein the elastomeric member comprises silicone rubber having a smooth, convex surface.
Claim 10
Dependent Claim
175 words
A process for transferring a decorative laminate from a support to an article, comprising the steps: heating the laminate, which is comprised of a nonwax-based adhesive/releaser layer in contact with the support, and a design layer, to a first temperature above the melting point of said adhesive/release layer, said laminate not having a wax-based release layer intermediate said adhesive/release layer and the support; heating the surface of an elastomeric member to a second temperature below said first temperature; contacting the laminate under pressure with the heated elastomeric member so that the laminate adheres to the elastomeric member and separates from the support upon withdrawal of said elastomeric member; impressing the laminate against the article to bond the adhesive/release layer thereto; and withdrawing the elastomeric member from the article, whereupon the laminate remains permanently adhered to the article, the time interval between contact of the laminate against the article and withdrawal of the elastomeric member from the article leaving the laminate permanently adhered to said article is in a range between about 0.01 and 0.2 seconds.
Claim 11
Dependent Claim
175 words
A process for transferring a decorative laminate from a support to an article, comprising the steps: heating the laminate, which is comprised of a nonwax-based adhesive/releaser layer in contact with the support, and a design layer, to a first temperature above the melting point of said adhesive/release layer, said laminate not having a wax-based release layer intermediate said adhesive/release layer and the support; heating the surface of an elastomeric member to a second temperature below said first temperature; contacting the laminate under pressure with the heated elastomeric member so that the laminate adheres to the elastomeric member and separates from the support upon withdrawal of said elastomeric member; impressing the laminate against the article to bond the adhesive/release layer thereto; and withdrawing the elastomeric member from the article, whereupon the laminate remains permanently adhered to the article, the time interval between contact of the laminate against the article and withdrawal of the elastomeric member from the article leaving the laminate permanently adhered to said article is in a range between about 0.01 and 0.2 seconds.
Claim 12
Dependent Claim
20 words
A process as defined in claim 9 wherein the transferred laminate on the article is not subjected subsequently to firing.
