Patent number: 4510206Abstract: A thermal ink transfer laminate wherein an ink design is transferred from a carrier support to an article, typically paper, by application of a thermal printing element to the nontransfer side of the carrier. The thermal ink transfer laminate is composed of a carrier support of paper or plastic film overcoated on one side with a heat sensitive ink coating. The heat sensitive ink coating is composed of a hot melt mix containing a coloring agent, a wax binder, and a resin binder.The coloring agent contains a dye dispersed in an unsaturated fatty acid medium. The wax binder contains a paraffin and microcrystalline wax. The coloring agent in combination with the wax binder greatly facilitates attainment of a drastic drop in melt viscosity of the design layer during thermal transfer onto a receiving article. The degree of transfer attained is virtually complete resulting in a transferred image of exceedingly high image clarity and definition.Type: GrantFiled: August 22, 1983Date of Patent: April 9, 1985Assignee: Dennison Manufacturing CompanyInventor: Ralph J. Shuman

Patent number: 4508775Abstract: Flexible, microporous, hydrophobic and oleophobic film-like composite structures comprised of from about 25 to about 75 parts by weight of inorganic reinforcing microfibers, particularly glass, and from about 75 to about 25 parts by weight of a polymeric binding agent, preferably a copolymer of ethylene and vinyl acetate, the polymeric binding agent being in the form of a continuous matrix and derived from an emulsion or latex of the binding agent in which the particles of the binding agent are less than about 1 micrometer in size. A treating agent, preferably a fluorinated hydrocarbon, is present in an amount sufficient to render the composite structure hydrophobic and oleophobic.Type: GrantFiled: December 28, 1983Date of Patent: April 2, 1985Assignee: Pall CorporationInventor: Joseph G. Adiletta

Patent number: 4507669Abstract: A thermosensitive recording sheet comprising a support material; a primer layer formed on support material, comprising a filler and a binder agent; a thermosensitive coloring layer formed on the primer layer, comprising a colorless or light-colored leuco dye, and an acidic material which colors the leuco dye upon application of heat thereto; and a protective layer formed on the thermosensitive coloring layer, comprising a water-soluble polymeric binder agent and a filler. This thermosensitive recording sheet has high dynamic thermal coloring sensitivity and is capable of yielding sharp images with high image density at low energy consumption with good thermal-head-matching properties such that materials are not generated which come out of the thermosensitive recording layer and adhere to the thermal pen or head during the recording process, thereby causing the thermal pen or head to stick to the thermosensitive recording sheet.Type: GrantFiled: January 28, 1983Date of Patent: March 26, 1985Assignee: Ricoh Company, Ltd.Inventors: Hiroshi Sakamoto, Yoshihiro Koseki, Takanori Motosugi, Norihiko Inaba

Patent number: 4507349Abstract: A security medium, secure articles made therefrom and methods of making same. Articles are disclosed which are resistant to counterfeiting and unauthorized alteration and which are suitable for use as currency, securities, security passes, identification cards, and analogous items now usually manufactured on paper. The novel articles comprise two synthetic material layers with a barrier layer therebetween and an image formed from sublimatable dye within at least one of the synthetic layers.Type: GrantFiled: May 16, 1983Date of Patent: March 26, 1985Assignee: Howard A. FromsonInventors: Howard A. Fromson, Robert F. Gracia
