Abstract

A metal leaf adhesive transferring sheet is disclosed and includes a transfer sheet which is provided with a paper backing and a release layer. The release layer of the transfer sheet is coated with an adhesive. The adhesive may be transferred to a substrate by either burnishing an image on the first side of the transfer sheet or wetting the transfer sheet if a water release type release sheet is used. Thereafter, metal leaf may be applied to the adhesive image that is transferred to the substrate. A method of transferring metal leaf to a substrate is also disclosed.

Claims

1. A method of transferring adhesive to a substrate, comprising the steps of:

providing a transfer sheet having a paper backing, said paper backing having first and second sides, a release layer formed on said second side and an adhesive coating layer deposited on said release layer;

placing said transfer sheet on the substrate;

burnishing said first side of said paper backing so that said adhesive coating in the shape of an image is transferred to the substrate;

removing said transfer sheet from the substrate, said transfer sheet having said adhesive coating layer where said first side is not burnished; and

applying metal leaf to said transferred adhesive coating to create a metal leaf image.

2. The method of transferring adhesive to a substrate to be metal leafed according to claim 1, wherein said adhesive is a pressure sensitive adhesive.

3. The method of transferring adhesive to a substrate to be metal leafed according to claim 2, wherein said pressure sensitive adhesive is an automotive adhesive.

4. The method of transferring adhesive to a substrate to be metal leafed according to claim 2, wherein said pressure sensitive adhesive is thinned up to 20 percent with water, and wherein said pressure sensitive adhesive is clear in color.

5. The method of transferring adhesive to a substrate to be metal leafed according to claim 2, wherein said pressure sensitive adhesive is colored with water soluble pigments.

6. The method of transferring adhesive to a substrate to be metal leafed according to claim 1, wherein said metal leaf is gold leaf.

7. The method of transferring adhesive to a substrate to be metal leafed according to claim 1, wherein said metal leaf is a bronze leaf.

8. The method of transferring adhesive to a substrate to be metal leafed according to claim 1, wherein said transfer sheet is a dry transfer sheet.

9. The method of transferring adhesive to a substrate to be metal leafed according to claim 1, wherein said transfer sheet is a water release decal type transfer sheet.

10. The method of transferring adhesive to a substrate to be metal leafed according to claim 1, wherein said transfer sheet is translucent.

11. The method of transferring adhesive to a substrate to be metal leafed according to claim 1, wherein said transfer sheet is a parchment release paper.

12. The method of transferring adhesive to a substrate to be metal leafed according to claim 1, wherein after said providing step an image is sketched upon said paper backing side of said transfer sheet.

13. The method of transferring adhesive to a substrate to be metal leafed according to claim 12, wherein said image is prepared by a computer.
