Abstract

In a process for the production of a stamping foil such as a hot stamping foil having a decorative layer provided on a carrier film only in a region-wise manner, corresponding to a desired patterning of the substrate, negative regions of the decorative layer, which do not remain on the carrier film, are removed from the carrier film of the stamping foil by being pulled off by means of a recipient foil.

Claims

1. A process for the production of a stamping foil comprising a carrier film and a decorative layer which is releasably arranged on the carrier film in a region-wise manner corresponding to a desired patterning for a substrate and which is adapted to be transferred onto a substrate, the process comprising

contacting a recipient foil under action of at least one of heat and pressure applied directly to the recipient foil, with regions of the decorative layer in which no decorative layer is wanted on the carrier film of the stamping foil such that the decorative layer adheres to the recipient foil in said regions in which no decorative layer is wanted, wherein the decorative layer is present over a large area on the carrier film of the stamping foil, and the recipient foil comprises a carrier film and an adhesive layer portion, said adhesive layer portion having substantially better adhesion with respect to the carrier film of the recipient foil and with respect to the decorative layer of the stamping foil, than adhesion of the decorative layer of the stamping foil to the carrier film of the stamping foil, and

pulling off the recipient foil with region-wise entrainment of the decorative layer from the carrier film of the stamping foil such that the decorative layer remains on the carrier film of the stamping foil in regions corresponding to the desired patterning.

2. The process of claim 1, wherein the recipient foil is contacted with the regions of the decorative layer of the stamping foil to be pulled off in a point-wise manner.

3. The process of claim 2, wherein the recipient foil is contacted with the regions of the decorative layer of the stamping foil to be pulled off using a thermal transfer print head.

4. A process for production of a hot stamping foil for application to a substrate, the foil comprising a carrier film and a decorative layer releasably arranged on the carrier film in a region-wise manner corresponding to a desired patterning for a substrate and which is adapted to be adhesively transferred onto a substrate, the process comprising

providing a hot stamping foil including a carrier film and a decorative layer which is releasably carried on the carrier film over an area of the carrier film;

providing a recipient foil which has an adhesive property in relation to the decorative layer of the stamping foil;

bringing the recipient foil into adhesive contact with the decorative layer in regions in which no decorative layer is wanted on the carrier film, whereby the decorative layer adheres to the recipient foil in said regions in which no decorative layer is wanted; and

separating the recipient foil and the stamping foil, whereby said recipient foil pulls said regions of the decorative layer in which no decorative layer is wanted off the carrier film of the stamping foil and portions of the decorative layer remain on the carrier film in regions corresponding to said desired patterning.
