    • An ink jet printing medium is disclosed. It contains (a) a substrate; (b) an ink absorption layer; and (c) a reinforcement layer sandwiched between said substrate and said ink absorption layer. The reinforcement layer, which is provided at a thickness about 5% to 100% of a thickness of said ink absorption layer, comprises: (a) a carboxylated acrylonitrile rubber at about 7 to 25 wt %; (b) an epoxy resin containing at least two epoxy groups, about 45 to 70 wt %; (c) a hardener containing at least two functional groups, provided at an equivalent ratio of between about 0.9 and 1.1 relative to said epoxy resin; and (d) a catalyst. The inkjet printing medium exhibits excellent adhesion between the ink absorption medium and the substrate, and improved water resistance without affecting printing quality.
    • 公开了一种喷墨打印介质。 它包含(a)底物; (b)吸墨层; 和(c)夹在所述基材和所述墨吸收层之间的加强层。 以所述油墨吸收层的厚度的约5%至100%的厚度提供的加强层包括:(a)约7至25重量%的羧化丙烯腈橡胶; (b)含有至少两个环氧基的环氧树脂,约45至70重量%; (c)含有至少两个官能团的硬化剂,其相对于所述环氧树脂以等于或大于0.9和1.1的当量比提供; 和(d)催化剂。 喷墨打印介质在油墨吸收介质和基材之间表现出优异的粘附性,并且改善了耐水性而不影响印刷质量。

    • The present invention relates to ink jet recording materials and method for making the same. The material has a gel layer formed on a base material to improve the optical density of the material and improve the printing quality of ink of pigment type. The method for forming the gel layer is to coat a first ink-receptive layer composed of high valance metallic halide, such as calcium chloride (CaCl2) or magnesium chloride (MgCl2), on the base layer, then a second ink-receptive layer composed of alginate, such as sodium alginate, potassium alginate or other compounds of alginic acid, on the first ink-receptive layer. The second and the first ink-receptive layers will react to form a gel layer during coating for absorbing ink dots and improving print quality.
    • 喷墨记录材料及其制造方法技术领域本发明涉及喷墨记录材料及其制造方法。 该材料具有形成在基材上的凝胶层,以提高材料的光密度并提高颜料类型的油墨的印刷质量。 用于形成凝胶层的方法是在基层上涂覆由高价金属卤化物(如氯化钙(CaCl 2)或氯化镁(MgCl 2))组成的第一油墨接收层,然后由第二油墨接收层组成 的藻酸盐,例如海藻酸钠,藻酸钾或其他海藻酸​​化合物,在第一油墨接受层上。 在涂覆期间,第二和第一墨水接收层将反应形成凝胶层,以吸收墨点并提高打印质量。
