  • Patent number: 6416845
    Abstract: A printing sheet is disclosed from which burned sheets, such as, e.g., a management label effectively utilizable from the production of Braun tubes to the salvage thereof, which are excellent in chemical resistance, heat resistance, weatherability, hiding power or reflectance, etc., can be formed while satisfying advantages such as the bondability to curved surfaces which enables the printing sheet, after having been printed according to circumstances to impart information thereto, to be tightly bonded to adherends with heating, the suitability for expedient printed-sheet formation in which a variety of printed sheets necessary for the production of small quantities of many kinds of products can be formed therefrom in situ, etc. according to circumstances, and the ability to be easily and tightly bonded to adherends. The printing sheet (1) comprises a sheet made of a mixture comprising inorganic particles, an MQ resin, and a silicone rubber.

  • Patent number: 6410097
    Abstract: A process which is for efficiently producing a silicone-based printing sheet and capable of forming an ink-receiving layer which is excellent in the fixability of a thermal transfer ink thereto and can be peeled off easily. The process comprises spreading a coating liquid containing at least a cellulosic polymer and a silicone resin as components on a carrier film wherein at least a surface layer on the side to be coated with the coating liquid is made of poly(vinylidene fluoride), and drying the coating to form an ink-receiving layer.

  • Patent number: 6284369
    Abstract: A sheet for forming a burned pattern is provided which comprises a ceramic green sheet layer (1) to be burned and a pressure-sensitive adhesive layer (2), wherein the pressure-sensitive adhesive layer comprises either a single layer decomposable at low temperature and leaving a decreased amount of carbonaceous residues after burning or a laminated layer comprising at least two layers of an inner pressure-sensitive adhesive layer (21) which is the low-temperature-decomposable layer and an outer pressure-sensitive adhesive layer (22) having resistance to water washing. The pressure-sensitive adhesive layer of the sheet for forming a burned pattern shows excellent provisional adhesion to adherends before burning. In particular, the outer pressure-sensitive adhesive layer shows such adhesive strength that the sheet is prevented from peeling off upon water washing.

  • Patent number: 6280827
    Abstract: A sheet for printing, which comprises an ink-receiving layer comprising a fluoropolymer film, optionally having property to absorb or scatter ultraviolet rays; an ink comprising a fluoropolymer and a colorant; and a printed sheet comprising the sheet for printing and information comprising the ink formed on the ink-receiving layer of the sheet by thermal transfer printing. With the sheet for printing and the ink, it is possible to form a printed sheet having so high weatherability that the ink information, even upon outdoor weathering, does not disappear and retains satisfactory readability over long period of time without the necessity of forming a coating layer thereon, by imparting ink information in situ, etc. by thermal transfer printing according to circumstances.
