  The present invention relates to black coloring matter, and relates to a compound represented by the following formula (1): (wherein A and D independently represent an optionally substituted phenyl group or naphthyl group, respectively, and m and n represent 1 or 2, respectively), and the coloring matter for recording and an ink comprising the same. Said compound exhibits high solubility in a medium containing water as a main component, is stable even when an aqueous dye solution or an ink having a high concentration is prepared therefrom and is stored for a long period of time, has low color rendering property, exhibits colorless and neutral black, provides a printed image having high density and also provides a black recorded image being excellent in moisture fastness, light fastness and an ozone gas fastness, and further can be synthesized easily and can be produced at a low cost.

  本发明涉及黑色着色剂，涉及以下式（1）表示的化合物： （其中A和D分别独立地代表一个可选地取代的苯基或萘基，m和n分别代表1或2），以及用于记录的着色剂和包含该着色剂的墨水。所述化合物在水作为主要成分的介质中表现出高溶解性，即使从其中制备了高浓度的水基染料溶液或墨水并长时间储存，也非常稳定，具有低显色性，呈现出无色和中性黑色，提供高密度的印刷图像，并且提供具有优异的耐湿性、耐光性和臭氧气体稳定性的黑色记录图像，并且可以容易地合成，可以低成本生产。

  A colorant free from cellulose reactive groups comprising an anionic dye carrying from 1 to 10 acidic groups and at least one poly(C2-4-alkyleneimine) group containing from 2 to 10 C2-4-alkyleneimine units-. The colorant is adapted for the preparation of aqueous inks for use in the printing of paper to give prints having enhanced water-fastness. The black colorants of this class are especially suitable for use in ink-jet printing inks for the printing of alphanumerics and related symbols from computer output.

  一种不含纤维素活性基团的着色剂，包含一种带有 1 至 10 个酸性基团的阴离子染料和至少一个含有 2 至 10 个 C2-4 烷基亚胺单元的聚 C2-4 烷基亚胺基团。这种着色剂适用于制备水性油墨，用于纸张印刷，使印刷品具有更强的耐水性。该类黑色着色剂尤其适用于喷墨打印墨水，用于打印计算机输出的字母数字和相关符号。
