  • Patent number: 6730633
    Abstract: 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 1 for an adhesive layer comprises: a substrate sheet 2; and an adhesive layer 3 and an interposing layer 4 laminated in that order on the substrate sheet 2. The substrate sheet 2 and the adhesive layer 3 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.

  • Publication number: 20040058817
    Abstract: Disclosed is a thermal transfer image receiving sheet comprising a substrate sheet, an intermediate layer provided on at least one surface side of the substrate sheet and a dye receptor layer provided on the surface of the intermediate layer, wherein the substrate sheet is a pulp paper, the intermediate layer is formed from an organic solvent solution of a resin, and the dye receptor layer is formed from an aqueous resin liquid. By virtue of this structure, the thermal transfer image receiving sheet can be prevented from occurrence of curling caused by temperature change. Also disclosed is a thermal transfer image receiving sheet comprising a substrate sheet, an intermediate layer provided on at least one surface side of the substrate sheet and a dye receptor layer provided on the surface of the intermediate layer, wherein the intermediate layer is formed from either an acrylic resin or a resin at least a part of which is crosslinked.

  • Publication number: 20040038079
    Abstract: 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.
