A repeatability corresponding to the limit of possible repeated recording/erasing effected by a physical or chemical change in the material constituting the recording can be obtained. A deterioration in image quality caused by transfer of a part of the recording layer to the heating unit can be prevented and repeat characteristics can be improved, thereby limiting the running cost.Type: GrantFiled: January 13, 1997Date of Patent: November 17, 1998Assignees: Toppan Printing Co., Inc., Mitsubishi Denki Kabushiki KaishaInventors: Niro Watanabe, Yuji Nakatsu, Keiki Yamada, Masaru Ohnishi

Patent number: 5824395Abstract: A borderless decorative graphic transfer and its application which is applied to a gum and starch coated absorbent paper is disclosed. The printed image may be applied by non-soluble water, non-soluble ink or laser printer copy toner. After printing on the coated paper, an acrylic dusting is applied to the exterior. The overlay creates a non-continuous film graphic transfer with an invisible coating. Thereafter, the image can be transferred by heat, chemical, or contact adhesive.Type: GrantFiled: June 23, 1997Date of Patent: October 20, 1998Inventor: Richard S. Zemel

Patent number: 5789341Abstract: The present invention provides a method for fabricating an imaged film, comprising the steps of: providing a laminate film for thermal transfer comprising an opaque film layer having no affinity for a sublimating dye and a transparent film layer laminated on the opaque film layer; contacting a transfer paper having an image formed with a recording material containing the sublimating dye on a surface of the opaque film layer; and heating the transfer paper to diffuse the sublimated dye through the opaque film layer into the transparent film layer. The method enables one to fabricate an imaged film with which when viewed from the side of the transparent film surface opposite to the thermal transfer surface, a high density image backed by the opaque film appears on the film surface having excellent glossiness.Type: GrantFiled: April 1, 1997Date of Patent: August 4, 1998Inventor: Kenichi Furukawa
