Abstract

This invention relates to new hot-stamping films comprising a carrier film, a transparent covering lacquer layer which is provided on its surface facing away from said carrier film, with a spatial pattern, a decorative layer contacting the surface of the transparent covering lacquer layer provided with the spatial pattern, and an adhesive layer, optionally with a separating layer between the carrier film and the covering lacquer layer and optionally with an adhesion-promoter layer between the decorative layer and the adhesive layer, and to a process for their production and to apparatus for the manufacture by this process.

Claims

1. A hot-stamping film comprising a carrier film, a transparent covering lacquer layer having a smooth surface adjacent to the carrier film and being provided on its surface facing away from said carrier film with a spatial pattern, a decorative layer contacting the surface of the transparent covering lacquer layer provided with the spatial pattern, and an adhesive layer, optionally with a separating layer between the carrier film and the covering lacquer layer and optionally with an adhesion-promoter layer between the decorative layer and the adhesive layer.

2. A film according to claim 1, in which the decorative layer is a metal layer of substantially uniform thickness provided between the surface of the transparent covering lacquer layer carrying the spatial pattern, and the adhesive layer, or adhesion-promoter layer if present.

3. A film according to claim 2, in which the metal layer is vapour deposited on said surface.

4. A film according to claim 2, in which the metal layer has a thickness of about 500 A.

5. A film according to claim 1, in which the decorative layer is a pigmented lacquer layer provided between the surface of the transparent covering lacquer layer carrying the spatial pattern and the adhesive layer, or adhesion-promoter layer is present.

6. A film according to claim 5, in which the pigmented lacquer layer has a thickness of from 2 to 4μ

.

7. A film according to claim 1, in which the transparent covering lacquer layer has a thickness of from 1.5 to 3μ

.

8. A film according to claim 1, in which the transparent covering lacquer layer is formed by a lacquer which is thermoplastic at least during the application of the spatial pattern.

9. A film according to claim 1, in which the transparent covering lacquer layer is formed by a curable lacquer.
