Abstract
Abstract A method for transferring a fixed image, such as an electrographically produced toner image, from an initial substrate to a final substrate. The method employs an adhesive-coated film to lift the image from its initial substrate and to secure it to the final substrate. The film remains in place after the transfer is completed and serves to encapsulate and protect the image. Both the initial substrate and the adhesive-coated film are maintained dry during the process and the initial substrate remains intact and may be reused. Variations of the invention are disclosed whereby background or collage pieces may also be adhered to the adhesive coated film before the film is secured to the final substrate to thereby produce collages and special effects.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
232 words
A method for transferring a discrete toner image, which has been fixed and applied in a fusion process to a smooth and non-absorbent image-releasing substrate and which exists in a stable form outside of the process by which it was formed, from said image-releasing substrate to a final substrate, said method comprising the following: (a) selecting a target image to be transferred, said target image having one surface fused with but substantially and integrally detachable from the initial substrate and having an exposed surface not in contact with the initial substrate and accessible from one side of the initial substrate, (b) contacting said exposed surface of the target image and areas of said initial substrate adjacent to said image with a pressure-sensitive adhesive coating carried on one side of a transparent film to cause adhesion of the target image to said film, (c) separating the film from the initial substrate, while maintaining adhesion of target image to said film to thereby detach substantially all of the target image from said initial substrate, (d) positioning the adhesive side of the film with the target image attached over the desired location on the final substrate, (e) adhering the film to the final substrate to attach the target image thereto and encapsulate it, (f) maintaining all of the materials substantially dry throughout the process, and (g) maintaining all of the materials substantially at ambient temperature.
Claim 2
Independent Claim
232 words
A method for transferring a discrete toner image, which has been fixed and applied in a fusion process to a smooth and non-absorbent image-releasing substrate and which exists in a stable form outside of the process by which it was formed, from said image-releasing substrate to a final substrate, said method comprising the following: (a) selecting a target image to be transferred, said target image having one surface fused with but substantially and integrally detachable from the initial substrate and having an exposed surface not in contact with the initial substrate and accessible from one side of the initial substrate, (b) contacting said exposed surface of the target image and areas of said initial substrate adjacent to said image with a pressure-sensitive adhesive coating carried on one side of a transparent film to cause adhesion of the target image to said film, (c) separating the film from the initial substrate, while maintaining adhesion of target image to said film to thereby detach substantially all of the target image from said initial substrate, (d) positioning the adhesive side of the film with the target image attached over the desired location on the final substrate, (e) adhering the film to the final substrate to attach the target image thereto and encapsulate it, (f) maintaining all of the materials substantially dry throughout the process, and (g) maintaining all of the materials substantially at ambient temperature.
Claim 3
Dependent Claim
65 words
A method as set forth in claim 1 wherein said target image (is a toner image which) has been fused to said initial substrate in a xerographic process, and said target image, when contacted with said adhesive coating and viewed from the uncoated side of said transparent film, appears as a reverse of the image held on the electrostatic plate used in said xerographic process.
Claim 4
Dependent Claim
33 words
A method as set forth in claim 1 comprising the additional step of attaching a substantially rigid plate to at least one margin of said transparent film to assist in handling said film.
Claim 5
Dependent Claim
35 words
A method as set forth in claim 1 wherein a background piece is applied to said adhesive coating in a superimposed layer over the target image before the film is adhered to the final substrate.
Claim 6
Dependent Claim
55 words
A method as set forth in claim 1 further comprising burnishing the other side of the transparent film after the adhesive coating has been placed in contact with the target image and before the transparent film has been separated from the initial substrate to obtain good contact between the target image and the adhesive coating.
Claim 7
Dependent Claim
32 words
A method as set forth in claim 1 wherein the series of steps (a), (b) and (c) are successively repeated with at least a second target image before step (d) is performed.
Claim 8
Dependent Claim
23 words
A method as set forth in claim 1 wherein said target image has been fused to said initial substrate in an ink-jet process.
