  • Patent number: 6703088
    Abstract: The present invention provides a thermal transfer sheet, which comprises a substrate film and a metallic layer disposed on one side of the substrate film, the metallic layer being comprising leaf-shaped aluminum powder. The preferable leaf-shaped aluminum powder is obtainable via a process in which an aluminum film is formed by a vapor deposition on a peelability facilitating surface of a carrier sheet, the aluminum film is peeled off the carrier sheet and finely divided. Using the thermal transfer sheet, it is possible to produce a printed product having a high metallic luster and hiding property and excellent in qualities including design, appearance or decoration. Furthermore, it is not expensive to produce the thermal transfer sheet of the present invention.

  • Patent number: 6534154
    Abstract: Disclosed is an image-receiving sheet having better toner-fixing ability, an excellent image quality and high carriage quality in electrophotographic copying machines and printers. In an image-receiving sheet in which a layer containing a binder and a filler is formed on one surface of a substrate 1, the Beck smoothness of the containment layer is 2000 seconds or less and the haze of the image-receiving sheet is 5 to 15% to stabilize the carriage quality and to obtain a high quality image from OHP projectors. The containment layer is either one of a receptor layer 2 for recording an image or a backface layer 3 and in the image-receiving sheet, a layer having a Beck smoothness of 20000 seconds or less is formed on the surface opposite to the surface of the substrate 1 on which the containment layer is formed, thereby further bettering the carriage quality.

  • Patent number: 6444383
    Abstract: The present invention provides an image receiving sheet applicable to an over head projector (OHP) and a process for forming an OHP image. The image receiving sheet is capable of forming a yellow image providing a parallel-ray transmittance (Y) of 50% or more when the transmittance density (X) is in a range from 0 to 1.0 by electrophotography. The image receiving sheet is capable of forming a yellow image providing a haze value (Z) of 40% or less when the transmittance density (X) is in a range from 0 to 1.0 by electrophotography.

  • Patent number: 6410199
    Abstract: An image receiving sheet is provided for superior image reproduction. The image receiving sheet include a substrate and a receptor layer over at least one side of said substrate. The receptor layer includes a resin binder. The storage elasticity modulus of the resin binder is equal to or greater than 106 Pa at temperatures below about 40° C. and substantially satisfies the following relationships: G′130/G′200≦9.0 and G′130≦103 Pa, where G′130 is the storage elasticity modulus of the resin binder at 130° C. and G′200 is the storage elasticity modulus of the resin binder at 200° C.
