Abstract

The invention relates to a multi-layer film composite having at least one layer made of polycarbonate or copolycarbonate, characterized in that the polycarbonate or copolycarbonate comprises at least one additive of the general formulas (1) to (8), R1 are selected independently of each other from the group made of C10-C25-alkyl, C10-C25-alkoxy, and C10-C25-alkyl-substituted aryl, R2 are selected independently of each other from the group of C10-C25-alkylcarbonyl or hydrogen, and R3 are selected independently of each other from the group of C10-C25-alkyl.

Claims

1. A smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card comprising a multilayer foil composite comprising a layer comprising polycarbonate or copolycarbonate and an additive selected from the group of the compounds of the formulas (1) to (8) and mixtures thereof:

2. The smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card according to claim 1, wherein the additive is selected from the group consisting of pentaerythritol tetrastearate, glycerol monostearate, propanediol distearate, stearyl stearate and mixtures thereof.

3. The smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card according to claim 1, wherein the composite has a thickness of from 0.1 to 2 mm.

4. The smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card according to claim 1, wherein the layer is a coextruded foil.

5. A process for the production of a smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card according to claim 1, comprising laminating a foil comprising the layer comprising polycarbonate or copolycarbonate and an additive to another foil.

6. The smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card according to claim 1, wherein the additive does not comprise glycerol monostearate.

7. The smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card according to claim 1, wherein R3 represents a linear C10-C25 alkyl.

8. The smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card according to claim 1, wherein the additive is selected from the group consisting of compounds of the formulas (1) to (5), (7), (8), and combinations thereof.

9. The smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card according to claim 1, wherein the additive is selected from the group consisting of pentaerythritol tetrastearate, propanediol distearate, stearyl stearate and mixtures thereof.

10. The smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card according to claim 1, wherein the multilayer foil composite comprises at least two different polymeric layers.

11. The smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card according to claim 1, wherein the multilayer foil composite comprises at least two of the same polymeric layer.

12. A smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card comprising a multilayer foil composite comprising a layer comprising polycarbonate or copolycarbonate and an additive selected from the group of the compounds of the formulas (3) to (8) and mixtures thereof:

13. A smart ID card, identification document, portable data carrier, EC card, health card, credit card, or mobile-telephone card comprising a multilayer foil composite comprising a layer comprising polycarbonate or copolycarbonate and an additive selected from the group of the compounds of the formulas (4) to (8) and mixtures thereof:
