Abstract

The present invention relates to a workpiece which, on its surface, displays a depression having an opening width of at least 0.2 mm and in which depression a carrier material which is connected in a substantially inseparable manner to the workpiece and contains a characteristic marking material for the workpiece is disposed; and to a method for manufacturing the same and to a method for authentication and/or identification of the workpiece.

Claims

1. A workpiece which, on its surface, displays a depression having an opening width of at least 0.2 mm and in which depression a carrier material which is connected in a substantially inseparable manner to the workpiece and which contains a characteristic marking material for the workpiece is disposed.

2. The workpiece as claimed in claim 1, wherein the workpiece is made from metal, glass, wood, plastic and/or ceramic.

3. The workpiece as claimed in claim 1, characterized in that the depression displays a depth of 0.1-5 mm.

4. The workpiece as claimed in claim 1, wherein the carrier material is introducible into the depression in a liquid or pasty form and is then curable in the depression.

5. The workpiece as claimed in claim 4, wherein the carrier material is selected from glass and polymer compounds.

6. The workpiece as claimed in claim 1, wherein the marking material is selected from Stokes pigments and/or Anti-Stokes pigments, ceramic markers, and a material which has a characteristic which can be differentiated from the carrier material.

7. The workpiece as claimed in claim 1, wherein, on the surface of the depression, a pretreatment agent for improving adhesion is applied.

8. A method for manufacturing a workpiece as claimed in claim 1, wherein said method comprises the steps of:

a) introducing a depression having an opening width of at least 0.2 mm into the surface of a workpiece;

b) introducing a carrier material, which contains a characteristic marking material for the workpiece, in liquid or pasty form into the depression;

c) curing and connecting the carrier material in a substantially inseparable manner to the workpiece.

9. A method for authentication and/or identification of a workpiece as claimed in claim 1, comprising the steps of:

i) qualitative and/or quantitative reading of the marking material; and

ii) matching the reading result obtained in step i) with stored items of authentication and/or identification information for the workpiece.

10. The workpiece as claimed in claim 5, wherein the polymer compounds is epoxy resin, polyester resin, polyether resin, silicone resin and/or phenolic resin.

11. The workpiece as claimed in claim 2, wherein the carrier material is introducible into the depression in a liquid or pasty form and is then curable in the depression.

12. The workpiece as claimed in claim 11, wherein the carrier material is selected from glass and polymer compounds.

13. The workpiece as claimed in claim 12, wherein the polymer compounds is epoxy resin, polyester resin, polyether resin, silicone resin and/or phenolic resin.
