Patent number: 6232267Abstract: A thermal transfer sheet is comprises a substrate sheet, a dye layer of at least one color, a white layer to cover an image-receiving portion of a receiving material after an image is formed therein, and if necessary, a transferable receptor layer to be transferred to the image-receiving portion of the receiving material before the formation of the image, those layers being alternately disposed side by side on a surface of the substrate sheet, wherein said white layer being capable of adhering to the image-receiving portion already provided with the image and being disposed on the substrate sheet via a peeling layer interposed therebetween. The white layer has a white screenability to provide excellent light diffusivity and light transmissivity for a background of the printed image. The white layer may be formed by applying a coating liquid containing an adhesive binder resin and a white pigment or a coating liquid containing a binder resin, an adhesive, and a white pigment on the peeling layer.Type: GrantFiled: July 2, 1998Date of Patent: May 15, 2001Assignee: DAI Nippon Printing Co., Ltd.Inventors: Katsuyuki Oshima, Satoru Kawai, Hideki Usuki
