Material for making identification cards

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 .mu.m and a resin layer having a thickness of 30 to 500 .mu.m selected from the group consisting of a polyolefin layer, a polyvinyl chloride resin film layer and an ABS resin film layer.
