  • Patent number: 6623818
    Abstract: In a recording medium for a printer having a dye fixation layer mainly composed of an interlayer compound for receiving and holding a water-soluble dye by an intercalation reaction, and a binder, the ink is to be improved in ink absorption, fixation, water-proofness and bleeding characteristics to enable image formation to a high resolution. A dye fixation layer 3, mainly composed of an interlayer compound for fixing and holding the water-soluble dye by the intercalation reaction derived from the ion exchange action and the binder is formed as an outermost layer on a substrate 2. The binder of the dye fixation layer 3 contains the urethanated polyvinyl alcohol resin having an urethanation ratio of 1 to 20 mol %.

  • Patent number: 6277455
    Abstract: A polyester laminate film comprising plural polyester layers, which comprises one surface layer comprising a polyester and a lubricant having an average particle size of 1-3 &mgr;m in a proportion of 1-5 wt % and the other surface layer comprising a polyester wherein 5-15 mol % of the entire acid component is a dimer acid component, the polyester laminate film having a crystallization peak temperature of 80-120° C. under temperature rise of the film The polyester laminate film of the present invention has a lower crystallization peak temperature when the film is under temperature rise, as compared to conventional polyethylene terephthalate. As a consequence, the film is free of whitening upon retorting, even after the film was subjected to remelting treatment and rapid cooling for noncrystallization and unorienting. Therefore, the film serves well as a laminate film for food containers and beverage cans that undergo retort sterilization.
