PURPOSE:To obtain the subject fluid which is excellent esp. in jetting stability and storage stability. CONSTITUTION:This fluid comprises water, an org. solvent, and trisazo compds. of formulae I and II provided that, when the compds. are analyzed by liq. chromatography, the ratio (A/B) of the area (A) of the peak of the compd. of formula I to the area (B) of the peak of the compd. of formula II is 0.8 or lower. The fluid is excellent esp. in stability during storage or use, distinctness of image, resistances to heat, water, and light, etc. |
