    Abstract: An image formed by an arbitrary method, can be reproduced on an object (to which image transfer is performed) having a three-dimensional arcuated surface, e.g., a cylindrical object. An original plate sheet is prepared by forming an image on a transparent sheet by using an ink containing carbon. A transfer ink sheet having a hot-melt ink layer formed on its one surface and a reflecting layer formed on its other surface is placed on an object to which image transfer is performed. A cushion member having transparency is placed on the transfer ink sheet, and a transparent plate is stacked on the cushion member. When the transparent plate is urged against the object side, the cushion member is compressed. As a result, the original plate sheet is deformed along the outer surface shape of the object and is brought into tight contact therewith. A flash lamp is turned on in this state. An image portion absorbs infrared rays emitted from the flash to generate heat.

  • Patent number: 5312713
    Abstract: An information recording medium comprises a recording layer including a mixture of organic polysilane and oxo metallic phthalocyanine pigment. Information is recorded by adding heat or light to the recording layer. In a method for recording information onto the information recording medium, a decoloring reaction of oxo metallic phthalocyanine pigment is used which is caused by heating the recording layer to a temperature equal to or higher than a pyrolyzing point of organic polysilane.

  • Patent number: 5275912
    Abstract: A process for forming a color image which may be used to represent a printed color image to be obtained from a printing press comprising (a) forming a thermal dye transfer image in a polymeric dye image-receiving layer of an intermediate dye-receiving element by imagewise-heating a dye-donor element and transferring a dye image to the dye image-receiving layer, (b) laminating a polymeric dye-migration barrier layer to the imaged dye image-receiving layer, and (c) laminating the dye-migration barrier layer and imaged dye image-receiving layer together to the surface of a paper substrate. By applying a dye-migration barrier layer to the imaged dye image-receiving layer and subsequently laminating both layers to the paper substrate together, the final paper substrate is subjected to only a single lamination step, and wrinkles caused by multiple laminations can be virtually eliminated.

  • Patent number: 5258247
    Abstract: A photoimaged article having a protected image composed of a colored image on a support; and a thin, transparent, flexible, nonself supporting, protective layer on the surface of the image. The layer is substantially nontacky at room temperature, and has at least a major amount based on the weight of the layer of one or more thermoplastic resins of a vinyl acetal, vinyl chloride, or acrylic polymer or copolymer having a Tg of from about 35.degree. C. to about 110.degree. C. The layer is capable of being adhesively transferred directly to the image when the layer is first applied on the release surface of a temporary support, and the image and protective layer are laminated together under pressure at temperatures of between about 60.degree. C. to about 180.degree. C. with subsequent removal of the temporary support. The side of said layer opposite to the image is free from additional layers. The adhesive layer is one which does not cohesively block at temperatures of about 50.degree. C. or less.
