    • A mat type recording medium for ink jet printing is provided which exhibits optimum printability no matter which of dye ink and pigment ink may be used in printing. The recording medium, which is for recording with use of water-based ink containing an ink colorant, comprises a paper base and an ink receptive layer formed on a surface of the paper base, the ink receptive layer comprising a porous layer containing an inorganic pigment and also containing a substance reactive with the ink colorant. The recording medium is characterized in that a droplet of 4 μl distilled water dropped onto a surface of the ink receptive layer is absorbed in a first absorbing stage of absorbing the droplet at a first absorbing speed V1 (μl/sec) within one second after the dropping, a second absorbing stage of absorbing the droplet at a second absorbing speed V2 (μl/sec) after the first absorbing stage, and a third absorbing stage of absorbing the droplet at a third absorbing speed V3 (μl/sec) after the second absorbing stage, the droplet absorption in the first to third absorbing stages satisfying the relationships of 0
    • 提供了一种用于喷墨打印的垫型记录介质,其无论染料油墨和颜料油墨中哪一种都可用于印刷,其表现出最佳的印刷性。 用于使用含有油墨着色剂的水性油墨进行记录的记录介质包括形成在纸基表面上的纸基和油墨接受层,该油墨接收层包括含有无机颜料的多孔层 并且还含有与油墨着色剂反应的物质。 记录介质的特征在于,滴入到受墨层表面上的4摩尔蒸馏水的液滴被吸收在吸收第一吸收级的第一吸收级中,该吸收级在第一吸收速度V 1(mul / sec) 滴下,在第一吸收阶段之后以第二吸收速度V 2(mul / sec)吸收液滴的第二吸收阶段和以第三吸收速度V 3(mul / sec)吸收液滴的第三吸收级, 在第二吸收阶段之后,在第一至第三吸收阶段中的液滴吸收满足0

    • The present invention aims to provide an ink which has a sufficiently large area factor even in a small ink droplet quantity and can obtain images having a high image density, and further has a superior storage stability. According to the present invention, a cyan ink is provided which is used in an ink set having four kinds of aqueous inks consisting of a cyan ink, a magenta ink, a yellow ink and a black ink in which each ink comprises at least water, a water-insoluble coloring material, and a plurality of water-soluble organic solvents having a good medium or good mediums for the water-insoluble coloring material and a poor medium or poor mediums for the water-insoluble coloring material, wherein, the ratio B1/A1 is from 0.5 or more to 3.0 or less, where A1 denotes the total content (mass %) of the good medium based on the total mass of the cyan ink and B1 denotes the total content (mass %) of the poor medium based on the total mass of the cyan ink, and a water-soluble organic solvent which shows the maximum Ka value among the respective Ka values of the plurality of water-soluble organic solvents as determined by the Bristow method is the poor medium.
    • 本发明的目的在于提供即使在小的墨滴量中也具有足够大的面积因数并且可以获得具有高图像密度的图像的墨水,并且还具有优良的储存稳定性。 根据本发明,提供一种青色墨水,其用于具有四种由青色墨水,品红色墨水,黄色墨水和黑色墨水组成的水性墨水的墨水组合,其中每种墨水至少包含水, 水不溶性着色材料和多种水溶性着色材料介质或介质良好的水溶性有机溶剂和水不溶性着色材料的不良介质或不良介质,其中B比 1 1 <1 为0.5以上至3.0以下,其中,A 1表示良好介质的总含量(质量%) 基于青色墨水的总质量,B&lt; 1&lt; 1&gt;表示基于青色墨水的总质量的不良介质的总含量(质量%)和表示 通过Bristow法测定的多种水溶性有机溶剂的各Ka值中的最大Ka值是不良介质。

    • A cyan ink applicable to an ink set has plurality of aqueous inks each containing at least: water; a water-insoluble coloring material; and plurality of water-soluble organic solvents including a good medium or good mediums for the water-insoluble coloring material and a poor medium or poor mediums for the water-insoluble coloring material. A ratio of a poor medium to a good medium in the cyan ink is in a specific range. A water-soluble organic solvent showing the maximum Ka value out of respective Ka values of the plurality of water-soluble organic solvents is the poor medium. A ratio of a poor medium to a good medium in an arbitrary aqueous ink in the ink set except the cyan ink and the ratio of the poor medium to the good medium in the cyan ink satisfy a specific relationship.
