Abstract

An ID card material comprises a thermal transfer image-receiving layer, and provided thereon, a substrate layer and a writing layer in this order, the substrate layer comprising a biaxially oriented polyester film layer having a thickness of 300 to 500 μm and a resin layer having a thickness of 30 to 500 μm selected from the group consisting of a polyolefin layer, a polyvinyl chloride type resin film layer and an ABS resin film layer.

Claims

1. An ID card material comprising a thermal transfer image-receiving layer, and provided thereon, a substrate layer and a writing layer in this order, wherein the substrate layer comprises a biaxially oriented polyester film layer having a thickness of 300 to 500 μ

m and a resin layer having a thickness of 30 to 350 μ

m selected from the group consisting of a polyolefin layer, a polyvinyl chloride resin film layer and an ABS resin film layer.

2. The material of claim 1, wherein a white opaque layer is provided between the thermal transfer image-receiving layer and the substrate layer, between layers constituting the substrate layer or between the substrate layer and the writing layer, the white opaque layer comprising white pigment in an amount of 0.5 to 50% by weight.

3. The material of claim 1, wherein the biaxially oriented polyester film layer comprises white pigment in an amount of 0.5 to 50% by weight.

4. The material of claim 3, wherein an adhesive layer is further provided between the thermal transfer image receiving layer and the substrate layer.

5. The material of claim 3, wherein a white opaque layer is provided between the thermal transfer image-receiving layer and the substrate layer or between the substrate layer and the writing layer, the white opaque layer comprising white pigment in an amount of 0.5 to 50% by weight.

6. The material of claim 1, wherein the substrate layer comprises the biaxially oriented polyester film layer and the resin layer provided on each side thereof.

7. The material of claim 6, wherein the resin layer contains white pigment in an amount of 0.5 to 50% by weight.

8. The material of claim 6, wherein the resin layer is a polyethylene layer or a polypropylene layer.

9. The material of claim 8, wherein an adhesive layer is provided between the polyethylene layer or the polypropylene layer and the biaxially oriented polyester film layer.

10. The material of claim 9, wherein the biaxially oriented polyester film layer comprises white pigment in an amount of 0.5 to 50% by weight.

11. The material of claim 9, wherein the resin layer contains white pigment in an amount of 0.5 to 50% by weight.

12. An ID card material comprising a thermal transfer image-receiving layer, and provided thereon, a substrate layer and a writing layer in this order, wherein the substrate layer consists of a biaxially oriented polyester film layer having a thickness of 300 to 500 μ

m.

13. A process of producing an ID card comprising the steps of:

forming an image by a thermal transfer recording method on a thermal transfer image-receiving layer of an ID card material;

providing a protective layer on the formed image;

coating an ultraviolet-curable resin on the image-receiving layer; and

irradiating ultraviolet ray to the coated resin layer to cure the resin,

the ID card material comprising a thermal transfer image-receiving layer, and provided thereon, a substrate layer and a writing layer in this order, wherein the substrate layer comprises a biaxially oriented polyester film layer having a thickness of 300 to 500 μ

m and a resin layer having a thickness of 30 to 500 μ

m selected from the group consisting of a polyolefin layer, a polyvinyl chloride resin film layer and an ABS resin film layer.
