Patent number: 6410200Abstract: A coated transfer sheet comprising a substrate having a first and second surface; optionally at least one barrier layer overlaying said first surface, at least one release layer overlaying said at least one barrier layer or, when the barrier layer is not present, said first surface of the substrate; and an optional image receiving layer comprising an ethylene acrylic acid co-polymer dispersion; wherein the coated transfer sheet exhibits cold peel and hot peel properties when transferred, and may be used in electrostatic printers and copiers or other devices in which toner particles are imagewise applied to a substrate. The addition of elastomeric polymers and polyurethanes help provide enhanced wash stability and chemical stability.Type: GrantFiled: March 31, 2000Date of Patent: June 25, 2002Inventors: Scott Williams, Heather Penk, Heather Reid

Patent number: 6411369Abstract: A recording sheet includes a micro-capsule layer which includes a plurality types of micro-capsules colored with different colors, for example, primary or complimentary colors of a subtractive mixture. The micro-capsules are filled with core materials which are discharged when the micro-capsules are broken. Each type of micro-capsule is selectively broken by a selective temperature and pressure application. When a micro-capsule is broken, the core material blends out the color of the micro-capsule. Additionally, an image forming system includes a heating unit for selectively heating the micro-capsules by an output of a Joule heat or light irradiation. Different wavelengths of light are radiated by the light irradiation heating unit, which are absorbed depending upon an absorption band exhibited by the different colored micro-capsules.Type: GrantFiled: March 12, 1999Date of Patent: June 25, 2002Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Minoru Suzuki, Hiroshi Orita, Hiroyuki Saito, Katsuyoshi Suzuki, Koichi Furusawa
