There is provided a thermal transfer image-receiving sheet which can yield, on its receptive layer, a thermally transferred sublimation dye image possessing excellent resistance to hand cream, resistance to sebum, resistance to plasticizers, and resistance to fats and oil. The thermal transfer image-receiving sheet comprises: a substrate sheet; and, provided on at least one side of the substrate sheet in the following order, an intermediate layer and a dye-receptive layer, the intermediate layer comprising a resin layer comprising an inorganic pigment having an acicular crystal structure.

Thermal transfer image-receiving sheet

An image formation method and a thermal transfer sheet for use in the image formation method are provided. According to the image formation method and the thermal transfer sheet, an intermediate transfer recording medium comprising a substrate film and a transfer part, comprising at least a receptive layer, provided separably on the substrate film is used, and, at the time of the transfer of the transfer part in the intermediate transfer recording medium onto an object, the transfer of the transfer part onto the object in its nontransfer region, onto which the transfer part should not be transferred, can be avoided without installing any special ancillary tool on an image forming apparatus. In the method for image formation, a thermal transfer sheet comprising a substrate and at least a peel-off layer provided on the substrate is provided. Further, an intermediate transfer recording medium comprising a substrate film and a transfer part, comprising at least a receptive layer, provided separably on the substrate film is provided. The thermal transfer sheet and the intermediate transfer recording medium are put on top of each other so that the peel-off layer in the thermal transfer sheet is brought into contact with the transfer part in the intermediate transfer recording medium. The assembly is heated to remove the transfer part in its predetermined region from the intermediate transfer recording medium. The transfer part is then retransferred from the intermediate transfer recording medium onto an object. That is, the transfer part in its predetermined region in the intermediate transfer recording medium is transferred onto the thermal transfer sheet side provided with the peel-off layer and is separated from the intermediate transfer recording medium side.

A transfer sheet, for an adhesive layer, for use in the formation of an image by a thermal transfer process, an image forming method using the transfer sheet for an adhesive layer, and an object with an image formed thereon are disclosed. A transfer sheet for an adhesive layer comprises: a substrate sheet ; and an adhesive layer and an interposing layer laminated in that order on the substrate sheet . The substrate sheet and the adhesive layer are separable from each other. The use of the transfer sheet for an adhesive layer in combination with an intermediate transfer medium enables a desired image having a high quality to be efficiently formed on a particular article.

Transfer sheet for adhesive layer and use thereof

An image forming method for forming an image on an optical disk includes forming the image on an intermediate transfer medium or on an image receptive layer separably formed on one surface of the intermediate transfer medium. The intermediate transfer medium and the optical disk are laid so that the surface of the intermediate transfer medium carrying the image and the surface of the optical disk are in close contact with each other. Heat and/or pressure is applied to the intermediate transfer medium to transfer the image or the image receptive layer carrying the image to the optical disk to form a label on the optical disk.

A thermal transfer printer containing a means for feeding a plurality of thermal transfer sheets and a plurality of image receiving sheets, a platen roller placed in the feeding path of the thermal transfer and image receiving sheets, and a recording section with a thermal head with a plurality of heating resistors for selective activation based upon image data to record the image on the image receiving sheets when they and the thermal transfer sheets are forced together by the platen roller so each image receiving sheet is pressed on the thermal head surface by the platen roller. The recording section also has a means to detect when at least one of the thermal transfer and image receiving sheets being recorded are out and a means automatically to exchange the thermal transfer or image receiving sheets with new sheets based upon the detected result.

Photographing box

A transfer sheet, for an adhesive layer, for use in the formation of an image by a thermal transfer process, an image forming method using the transfer sheet for an adhesive layer, and an object with an image formed thereon are disclosed. A transfer sheet for an adhesive layer comprises: a substrate sheet and an adhesive layer and an interposing layer laminated in that order on the substrate sheet The substrate sheet and the adhesive layer are separable from each other. The use of the transfer sheet for an adhesive layer in combination with an intermediate transfer medium enables a desired image having a high quality to be efficiently formed on a particular article.

A photographing box is arranged to reduce a time taken from photographing an object to printing the image of the object. The photographing box is intended to be manufactured at low cost and more easily maintained. The photographing box includes a photographing mechanism house for housing a photographing mechanism and a photographing space section. If paid, the photographing device is operated to illuminate an object, photograph the object, and do some image processing like image magnification or reduction or image layout. Plural images sized for different uses are output on one cut sheet by a sublimation transfer printer. The photographing box operates to print out the image at high speed, and is manufactured at low cost and more easily maintained.

A thermal transfer recording system, there is prepared a thermal transfer sheet such as a sublimation or heat fusion thermal transfer sheet, and also prepared an intermediate transfer recording medium comprising a substrate sheet and a receptor layer disposed on the substrate sheet so as to be transferable; the thus prepared thermal transfer sheet is disposed together with the intermediate transfer recording medium between a heating device such as a thermal head and a platen roller; the thermal head is heated in accordance with an image information to be printed to thereby form the image in the receptor layer of the intermediate transfer recording medium; and thereafter, the image is transferred together with the receptor layer to a transfer-receiving material. When the image is formed to the intermediate transfer recording medium, the intermediate transfer recording medium is pressed at least at one area thereof from front surface side and back surface side thereof so as to fix a relative positional relationship between both ends in a width direction of the intermediate transfer recording medium, to thereby prevent shrinkage of the intermediate transfer recording medium in the width direction thereof.

Thermal transfer recording method and apparatus utilizing intermediate

According to the present invention, a gradation image such as photographs and a non-gradation image read by an image processing means 13 of FIG. 2 are edited and laid out. Based on the data file, a dye receiving layer 21 is formed on a gradation image forming area on a paper mount 26 of FIG. 3 by image generating means 18, and a gradation image 22 is formed by thermal transfer method on said dye receiving layer. A non-gradation image 23 such as character combined with the gradation image is printed before and after the formation of the gradation image. Further, a protective layer 24 is formed on the gradation image 22 or the non-gradation image 23 when necessary, by protective layer transfer means incorporated in the image forming means 18. Thus, a card such as a visiting card 20 with a photograph or a booklet such as a passport can be prepared. The gradation image and the non-gradation image can be transferred on plain paper, and by limiting the receiving layer area to the gradation image area, it is possible to form the images without impairing texture feeling and writability as plain paper. When the image is formed using a thermal transfer image receiving sheet with an arbitrary pattern (such as ground pattern), such pattern forms a background for the image, and this makes it possible to prevent falsification or alteration.
