  • Patent number: 7235596
    Abstract: The object of the present invention is to provide a flame-resistant fiber which possesses low negative effects on the environment and humans, such as emission of hazardous substances, which displays excellent both flame and weather resistance, and which does not reduce spinnability and fiber strength, and is able to provide a fiber molding obtained from the fiber. A flame-resistant fiber comprising at least one type of phosphazene derivatives selected from cyclic phosphazene derivatives and linear phosphazene derivatives, a hindered amine derivative containing specific groups, and a thermoplastic resin, wherein the fiber contains 0.25-5.0 wt % of the phosphazene derivative and 0.025-3.0 wt % of the hindered amine derivative, and the fiber fineness is 0.01-100 dtex.

  • Patent number: 5750200
    Abstract: An ink jet recording sheet comprising a support, at least one ink-receiving layer formed on the support, and a gloss-providing layer formed on the ink-receiving layer, said ink-receiving layer consisting essentially of a pigment and a binder, and said gloss-providing layer consisting essentially of a pigment and a synthetic polymer latex as a binder and having a glossy surface with a 75.degree. specular gloss of at least 25% as stipulated in JIS-Z8741, wherein at least 70 parts by weight in 100 parts by weight of the pigment in the gloss-providing layer are constituted by colloidal particles having an average particle size of at most 300 nm.

  • Patent number: 5302437
    Abstract: Disclosed is a coat type ink jet recording sheet which has on one side of a support a backcoat layer containing a specific platy inorganic pigment and on another side an ink-receiving layer containing at least one of starch particles, modified starch particles and ethylene-vinyl acetate copolymer resins, and a specific cationic dye fixing agent in such an amount as providing a specific cation charge per unit area of the recording sheet. This ink jet recording sheet is less in curling and cockling in wide ranges of temperature and humidity, improved in runnability on recording apparatuses, high in light resistance and ozone resistance of recorded images and in adhesion of the coating layers, less in blotting of overlapped color ink dots of the recorded images and besides, hardly undergoes yellowing.
