Thermal transfer printing |
摘要 |
An article for receiving an image by thermal transfer printing includes an image-receiving surface of plastics material coated with a layer of dye-receptive material capable of accepting an image by means of a dye thermal transfer process, wherein the glass transition temperature (Tg) of the dye receptive material is at least 50° C. lower than the softening point of the plastics material of the image-receiving surface. By having a difference between the softening point of the plastics material article surface and the Tg of the material coated thereon of at least 50° C. it is possible to achieve printing in a single step transfer process of high density images without distortion of the plastics material. The invention can be used with three-dimensional articles possibly having compound curves, including casings for mobile telephones made of polymers such as polycarbonate.
