摘要： A water-dispersible polyester composition for an image recording medium, comprising (1) a polyester having a glass transition temperature of not less than 40.degree.C., a specific gravity of not less than 1.25, a value of SP of 9.5-12.0, and at least one kind of hydrophilic polar group, and which is insoluble in methyl ethyl ketone, toluene, and a mixed solvent thereof, wherein 65% by mole or more of a glycol component constituting the polyester is ethylene glycol, in a proportion of 5-50% by weight, (2) an organic compound compatible with water in a proportion of 0-20% by weight, and (3) water in a proportion of 30-95% by weight all percentages by weight being based upon the total weight of said composition containing components (1), (2) and (3). When used for an image recording layer of an image recording medium, the composition of the invention is conducive to the durability of the recorded images excellent in heat resistance, resistance to plasticizer, resistance to fingerprint, and solvent resistance.

摘要： A coated film having an overall thickness of 5-50 μm is provided. A substrate made of a polymer resin composition may be laminated with a coating layer including a melamine series compound and a poly (vinyl alcohol)-based polymer to form the coated film. Further, an inorganic thin film layer may be vapor-deposited on the coating layer of the coated film to form a vapor-deposited film. Certain embodiments of the vapor-deposited film may have oxygen permeability and moisture vapor permeability before and after the gelbo test that satisfies the following formula: ( permeability after gelbo test - permeability before gelbo test ) ( permeability before gelbo test ) ≤ 0.2

摘要： A layered polyamide film includes a polyamide substrate; and an adhesiveness-improving layer provided on at least one surface of the polyamide substrate. The adhesiveness-improving layer includes a graft copolymer of a polyester and an acrylic polymer. Another layered polyamide film includes a printing ink layer, an adhesive layer, and a sealant layer sequentially laminated on the adhesiveness-improving layer. A method for producing such a layered polyamide film includes the step of applying an aqueous dispersion of the graft copolymer of the polyester and the acrylic polymer to at least one surface of the polyamide substrate to form an adhesiveness-improving layer and, if necessary, laminating a printing ink layer, an adhesive layer, and a sealant layer on adhesiveness-improving layer.
