Aqueous ink, ink cartridge, and ink jet recording method

The invention relates to an aqueous ink, an ink cartridge, and an ink jet recording method. Provided is an aqueous ink for inkjet which is capable of recording an image having excellent wear resistance and color rendering properties. The aqueous ink for inkjet includes: a pigment; wax; a phosphate ester-based surfactant; and an amine compound. The pigment is dispersed by the action of at least one selected from the group consisting of a carboxylic acid group and a sulfonic acid group. And the phosphate ester surfactant contains a fatty alcohol alkoxylation site. The ratio of the 50% cumulative particle diameter of the wax on a volume basis to the 50% cumulative particle diameter of the pigment on a volume basis is 0.10-2.0 times (inclusive). 本发明涉及水性墨、墨盒和喷墨记录方法。提供一种能够记录耐磨损性和显色性优异的图像的喷墨用水性墨。所述喷墨用水性墨包含：颜料；蜡；磷酸酯系表面活性剂；和胺化合物。所述颜料是通过选自由羧酸基和磺酸基组成的组的至少一种的作用而分散的颜料。所述磷酸酯系表面活性剂含有脂肪醇烷氧基化部位。蜡的体积基准的50％累积粒径与颜料的体积基准的50％累积粒径之比为0.10倍以上且2.0倍以下。
