    摘要： A recording liquid comprising a coloring material, an organic solvent to disperse or to dissolve said coloring material, water, and a calix[n]arene-p-4-sulfonic acid(wherein n=4-8) in the form of free acid or its metal salt. The recording liquid is very suitable for inkjet recording using plain paper as recording medium, The recording liquid shows high storage stability, excellent color reproducibility with hard blurring property of mutual colors at superimposed area thereof, and high resistivity for light fading, for the sake of buffering nature based by both ion capturing and releasing, and hydrophobic material capturing and releasing bestowed by above-mentioned calix compound.

    摘要： A recording liquid comprising a coloring agent and water, wherein the recording liquid contains a polyol (A) having a solubility in water at 20°C of 0.2 wt.% or more and not more than 4.5 wt.%, and at least one compound (B) selected from a group consisting of compound represented by formula (1) R 1 ,R 2 ,R 3 · N→O (where R 1 and R 2 are an alkyl group or a hydroxyalkyl group having 1 to 3 carbon atoms, and R 3 is an alkyl group or an alkenyl group having 10 to 20 carbon atoms ), and of compound represented by formula (2) represented by R 4 ,R 5 ,R 6 · N―CH 2 ―CO―O - (where R 4 and R 5 are an alkyl group or hydroxyalkyl group having 1 to 3 carbon atoms, and R 6 is an alkyl group or alkyl group derived from cocoanut oil having 10 to 16 carbon atoms that may contain an amide group). The recording liquid shows synergistic effect including a high permeability with modified penetrating property capable of eliminating an increase in optical density at the backside-surface of the printing medium, anti-color bleeding property, and an effect on reduction of blurring of colors, by the combined use of the polyol (A) and compound (B). The polyol (A) has a small molecular weight so that the adsorbing speed onto the surface to be printed is very high, and has a property to render the nitrogen moiety of the compound (B) into positive charge. The compound (B) acts on compound (A) to make it insoluble.

    摘要翻译： 一种包含着色剂和水的记录液，其中所述记录液含有在20℃下在水中的溶解度为0.2重量％以上且不超过4.5重量％的多元醇（A）和至少一种化合物 （B）选自由式（1）表示的化合物，R1，R2，R3组成的组。 N - > O（其中R 1和R 2是烷基或具有1至3个碳原子的羟烷基，R 3是烷基或具有10至20个碳原子的链烯基）和由式（2 ）由R4，R5，R6表示。 N-CH2-CO-O < - ）其中R4和R5是具有1至3个碳原子的烷基或羟烷基，R6是衍生自具有10至16个碳原子的椰子油的烷基或烷基， 含有酰胺基）。 记录液体具有协同效果，包括具有改善的穿透性的高渗透性，能够消除打印介质的背面的光密度增加，防着色性，以及减少颜色模糊的效果。 多元醇（A）和化合物（B）的组合使用。 多元醇（A）具有小分子量，使得要印刷的表面上的吸附速度非常高，并且具有使化合物（B）的氮部分成为正电荷的性质。 化合物（B）作用于化合物（A）使其不溶。
