Patent number: 4735860Abstract: A heat-resistant thermal transfer sheet comprising a base film provided on one surface thereof with a hot melt ink layer and with a heat-resistant protective layer on the other surface thereof. The heat-resistant protective layer is produced from a composition comprising (a) a thermoplastic resin having an OH or COOH group, (b) a polyamine or polyisocyanate, and (c) a thermoplastic resin, or a composition based on a silicone-modified resin. The heat transfer sheet of the present invention prevents sticking and blocking problems and makes it possible to carry out printing smoothly.Type: GrantFiled: December 6, 1985Date of Patent: April 5, 1988Assignee: Dai Nippon Insatsu Kabushiki KaishaInventors: Akira Mizobuchi, Yoshiaki Hida, Shigeki Umise, Kyoichi Yamamoto, Kyohei Takahashi

Patent number: 4579804Abstract: An image forming material comprises an image forming layer disposed on a support and comprising (a) aqueous composition comprising a hydrophilic binder layer containing metal developing nuclei or their precursor compound, and water and (b) an organic composition comprising an oil-soluble development inhibitor which is a compound having a diazo group or azide group and a water-miscible organic solvent. An image is formed by exposing the image forming layer to patternized light and then contacting it with a developer containing reducible metal ions and a reducing agent thereby to form an image constituted by metal particles grown at the light-exposed parts.Type: GrantFiled: February 22, 1983Date of Patent: April 1, 1986Assignee: Dai Nippon Insatsu Kabushiki KaishaInventors: Satoshi Takeuchi, Masanori Akada, Ryohei Takiguchi, Yoshiaki Hida, Hideki Takematsu
