Abstract
Abstract The first layer of elastomeric synthetic resin transparent ink is screened onto a transfer sheet and is fused. One or more layers of compatible ink are deposited thereon and dried to form an image. Next, an elastomeric adhesive protective layer is applied and fused. The intermediate article thus produced by this process is a transfer sheet carrying a transfer lamination which is applicable to fabric. The adhesive layer is applied against the fabric with pressure, and the entire structure is heated. During this heating, the elastomeric adhesive is absorbed into the fabric and is cured in place to become thermoplastic. At the same time, the first layer against the transfer sheet becomes plastic and the transfer sheet is removed. In another embodiment, the first and protective layers are fused and an additional elastomeric adhesive layer is applied unfused. During the transfer with the application of heat and pressure, the final layer performs the adhesive function, is absorbed into the fabric, and fuses.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
105 words
A transfer lamination having transfer layers for the application of an image onto fabric substrate, said transfer layers consisting of: a transparent first layer which forms a tough rubbery film which has a high degree of thermal stability and is resistent to yellowing; at least one image-carrying layer printed on the back of said first layer by a surface-to-surface printing method; and an adhesive layer forming the back layer of said transfer lamination for adhesive attachment of said transfer lamination to a resilient substrate said adhesive layer forming a tough rubbery film which has a high degree of thermal stability and is resistent to yellowing.
Claim 2
Dependent Claim
105 words
A transfer lamination having transfer layers for the application of an image onto fabric substrate, said transfer layers consisting of: a transparent first layer which forms a tough rubbery film which has a high degree of thermal stability and is resistent to yellowing; at least one image-carrying layer printed on the back of said first layer by a surface-to-surface printing method; and an adhesive layer forming the back layer of said transfer lamination for adhesive attachment of said transfer lamination to a resilient substrate said adhesive layer forming a tough rubbery film which has a high degree of thermal stability and is resistent to yellowing.
Claim 3
Dependent Claim
23 words
The transfer lamination of claim 1 wherein said first layer and said adhesive layer are formed of heat resistant thermal elastic stretch ink.
Claim 4
Dependent Claim
15 words
The transfer lamination of claim 2 wherein said adhesive layer is pigmented to be opaque.
Claim 5
Dependent Claim
16 words
The transfer lamination of claim 3 wherein said adhesive is adhesively secured to a fabric substrate.
Claim 6
Dependent Claim
23 words
The transfer lamination of claim 4 wherein said adhesive layer is a thermally cured adhesive and is thermally bonded to said fabric substrate.
Claim 7
Dependent Claim
42 words
The transfer lamination of claim 1 further consisting of: a transfer sheet to which said first layer is secured for the support of said first layer during the application of said image layer, and said adhesive layer, for handling said transfer lamination.
Claim 8
Dependent Claim
23 words
The transfer lamination of claim 6 wherein said first layer and said adhesive layer are formed of heat resistant thermal elastic stretch ink.
Claim 9
Dependent Claim
15 words
The transfer lamination of claim 7 wherein said adhesive layer is pigmented to be opaque.
Claim 10
Dependent Claim
192 words
In a process for producing a transfer lamination employed to apply an image to a flexible substrate which comprises the steps of forming a first transparent layer, printing an image layer onto the first layer, applying an adhesive layer to the image layer so that the three layers form a transfer lamination which can be adhesively applied to a flexible substrate, and drying and curing said layers, the improvement wherein: the first transparent layer is formed on a transfer sheet by applying a layer of transparent polyvinyl chloride plastisol heat resistant thermal elastic stretch ink to a release surface of the transfer sheet and partially curing said layer by infrared heating; the image layer is formed on the first layer so as to be visible through the first layer by lithographically printing heat resistant ink which is compatible with the first layer on to said first layer; and the adhesive layer is formed by applying a polyvinyl chloride plastisol heat resistant thermal elastic stretch ink over the first layer and the image layer; said layers being partially cured such that the first layer and adhesive layers are not tacky at room temperature.
