Patent number: 7776435Abstract: The present invention is an electrophotographic transfer paper where at least one side of the base paper is given a coating layer with a pigment and an adhesive agent to form coated paper and where the aforementioned adhesive contains a branched poly(meth)acrylamide copolymer having a cationic groups and/or anionic groups and also has a weight average molecular weight of 50,000 to 1,000,000. The electrophotographic transfer paper in the present invention has superior high-speed throughput performance despite low basis weight and a low coating weight, therefore, good for high-speed copy machine and printer properties, especially, when it contained a printability improver in the coating layer, it has a good ink adhesion property and surface strength required in offset printing.Type: GrantFiled: August 15, 2006Date of Patent: August 17, 2010Assignee: Nippon Paper Industries Co., Ltd.Inventors: Hisahiro Omote, Jiro Yoshimura, Akio Hoshino, Masahito Suzuki, Tomoyuki Nakano

Patent number: 5846367Abstract: Disclosed is a heat transfer recording method that utilizes an indirect transfer medium with deformable layer deforming under heat and/or pressure and image-receiving layer having adhesiveness to the image formed by fusion type heat transfer recording of hot peeling mode and allowing to retransfer the formed image alone onto image receiver provided on a supporter in this order. In this indirect transfer medium, the constituting material of that deformable layer comprises a substance with softening temperature of not higher than 90.degree. C. and stretch at breaking point of not less than 400%, and further the constituting material of the image-receiving layer contains a substance, in which the major component is acrylic resin comprising methyl methacrylate or/and hydroxyethyl methacrylate and this is graft copolymerized with hydroxyethyl methacrylate or/and N-methylol acrylamide.Type: GrantFiled: December 20, 1996Date of Patent: December 8, 1998Assignee: Nippon Paper Industries Co., Ltd.Inventors: Hisahiro Omote, Akio Hoshino, Mitsuhide Hoshino, Masahide Takano

Patent number: 5541035Abstract: A method of forming a multicolored image wherein image layers etc. formed on photosensitive transfer sheets are transferred in turn onto an image-receiving sheet and then, its image layer etc. are retransferred onto a permanent supporter. Both of a transferring image layer alone and a transferring image layer and adhesive layer are used properly for photosensitive transfer sheets. The finish quality comes close to original print and the runnability becomes better when making a color proof.Type: GrantFiled: May 18, 1994Date of Patent: July 30, 1996Assignee: Nippon Paper Industries Co., Ltd.Inventors: Hisahiro Omote, Satoshi Kuwabara, Masahide Takano

Patent number: 5273855Abstract: (Objective) In a color-proof material performed by forming multi-color image on an arbitrary material (ultimate image-receiving material) such as paper using a photosensitive transfer sheet and an intermediate image-receiving sheet, the objective is to bring the quality close to the printed quality formed with inks alone.(Constitution) For the photosensitive sheet, the colored photosensitive layer is formed with a material comprising a synthetic resin emulsion with Tg=-20.degree. to 40.degree. C. such as acrylic ester or ethylene-vinyl acetate copolymer so that the image layer itself has heat-adhesivity. Moreover, the image-receiving layer of the intermediate image-receiving sheet is formed with a material containing a resin cross-linked copolymer of olefin and .alpha., .beta.-unsaturated carboxylic acid with metallic ions and a resin comprising a copolymer of ethylene and vinyl acetate in a proportion by weight of 100/0 to 10/90.Type: GrantFiled: November 21, 1991Date of Patent: December 28, 1993Assignee: Sanyo-Kokusaku Pulp Co., Ltd.Inventors: Hisahiro Omote, Masahiro Yoshikawa, Masahide Takano
