    • An object of the present invention is to provide an ink, and ink jet recording method and apparatus using the ink which has excellent dispersion stability, discharge stability and recovery properties, and which can be kept in the weak alkali region even if it contains carbon black with low pH, which is generally considered to be difficult to handle and which can obtain a high-density image. The ink contains acid carbon black having a volatile content within the range 3.5 to 8% by weight, and a water-soluble resin having a weight average molecular weight within the range of 3,000 to 30,000, both of which are dissolved in an aqueous liquid medium, and a compound represented by the following formula (I), wherein the ratio by weight between the acid carbon black and the water-soluble resin is within the range of 3:1 to 10:1. R.sub.1 R.sub.2 NCONHCH.sub.2 CH.sub.2 OH (I) wherein R.sub.1 and R.sub.2 each is hydrogen or C.sub.n H.sub.2n OH, n is 2 or 3, with the proviso that R.sub.1 and R.sub.2 are not simultaneously hydrogen.
    • 本发明的目的是提供一种使用油墨的油墨和喷墨记录方法和装置,其具有优异的分散稳定性,排出稳定性和回收性能,并且即使含有炭黑也可以保持在弱碱区域 其pH低,通常被认为难以处理并且可以获得高密度图像。 油墨含有挥发成分在3.5〜8重量%范围内的酸性炭黑,重均分子量在3,000〜30,000的水溶性树脂中,均溶于水性液体介质 和由下式(I)表示的化合物,其中酸性炭黑和水溶性树脂之间的重量比在3:1至10:1的范围内。 R1R2NCONHCH2CH2OH(I)其中R1和R2各自为氢或CnH2nOH,n为2或3,条件是R1和R2不同时为氢。
