  • Patent number: 5112717
    Abstract: A toner bearing thermoplastic layer on a receiving sheet is textured or the gloss is improved by heating the thermoplastic layer from the rear to its glass transition temperature and contacting said sheet with a texturizing surface under sufficient pressure to texturize the layer. Offset of the thermoplastitc onto the pressure member contacting it is inhibited by not independently heating that member substantially above the glass transition temperature of the thermoplastic layer.
    Type: Grant

    Date of Patent: May 12, 1992
    Assignee: Eastman Kodak Company

  • Patent number: 5089363
    Abstract: A dry toner image is embedded in a thermoplastic layer on a receiving sheet by pressing a ferrotyping web against the image in the presence of sufficient heat to soften the layer. Preferably, the layer is preheated and the web and image are pressed together by a pair of hard rollers to a pressure in excess of 100 pounds per square inch.A curl preventing layer opposite thermoplastic layer does not offset on a backing roller because it has a melting point above the temperature of the process.

  • Patent number: 5087536
    Abstract: A toner image carrying thermoplastic layer on a receiving sheet is texturized from the back side of the sheet by positioning the sheet between a smooth hard surface and a texturizing surface with the texturizing surface contacting the back side. The thermoplastic layer is softened by heat and becomes texturized without embossing the back side. A curl preventing layer on the back side is not embossed because it has a melting point above the temperature of the process. A glossy-textured print can be produced this way. The process is especially useful in making multicolor prints of photographic quality.

  • Patent number: 5085962
    Abstract: A toner image, for example, a multicolor toner image is formed on a thermoplastic layer on a receiving sheet. To fix the image without substantial visible objectionable relief, the toner image is first positioned between two members, one of which has a rough texture to it to apply a texture to the toner image and the thermoplastic layer carrying it. It is then positioned between a pair of smooth surfaced pressure members to reduce the texture and relief and to apply a gloss to the image.
