Abstract

A composite foil from which metallically lustrous layer areas which have an image structure are to be transferred onto a base, with a carrier layer, with a lacquer layer on said carrier layer, with a metal layer on said lacquer layer and with an adhesive layer on said metal layer, wherein said lacquer layer (4) and said metal layer (8) are divided into areas which have the shape of the image structure, and wherein said carrier layer (2) can be detached from said lacquer layer (4) and the adhesive (14) which is located between the areas by pulling off said carrier layer at room temperature wherein the metal layer is formed from vapor deposited metal and adhesive (14) is a contact adhesive.

Claims

1. In a composite foil from which metallically lustrous layer areas which have an image structure are to be transferred onto a base, with a carrier layer, with a lacquer layer on said carrier layer, with a metal layer on said lacquer layer and with an adhesive layer on said metal layer, the improvement which comprises said lacquer layer (4) and said metal layer (8) being divided into areas which have the shape of the image structure, and wherein said carrier layer (2) can be detached from said lacquer layer (4) and the adhesive (14) which is located between the areas by pulling off said carrier layer at room temperature wherein the metal layer is formed from vapor deposited metal and adhesive (14) is a contact adhesive.

2. The composite foil of claim 1, wherein between said metal layer 8 and said lacquer layer 4 a layer 6 is located which is tinted in the same areas.

3. The composite foil of claim 2, wherein the basic material of said tinted layer 6 consists of a vinyl chloride-vinyl acetate copolymer.

4. The composite foil of claim 2 wherein said carrier layer 2 consists of a polyester foil.

5. The composite foil of claim 2 wherein said lacquer layer 4 consists of vinyl lacquer.

6. The composite foil of claim 2 wherein the tinting agent consists of a fat dyestuff, a dye which is soluble in alcohol, or an inorganic pigment.

7. The composite foil of claim 2 wherein said metal layer 8 consists of aluminum, copper, silver or chromium.

8. The composite foil of claim 1, wherein said lacquer layer 4 is tinted.

9. The composite foil of claim 8 wherein said carrier layer 2 consists of a polyester foil.

10. The composite foil of claim 8 wherein said lacquer layer 4 consists of vinyl lacquer.

11. The composite foil of claim 8 wherein the tinting agent consists of a fat dyestuff, a dye which is soluble in alcohol, or an inorganic pigment.

12. The composite foil of claim 8 wherein said metal layer 8 consists of aluminum, copper, silver or chromium.

13. The composite foil of claim 1 wherein said carrier layer 2 consists of a polyester foil.

14. The composite foil of claim 1 wherein said lacquer layer 4 consists of vinyl lacquer.

15. The composite foil of claim 1 wherein said metal layer 8 consists of aluminum, copper, silver or chromium.
