Ink-jet recording ink comprising water, a water-soluble organic solvent and a color material as essential ingredients, wherein the total volume of particulate matter ranges from 1.times.10.sup.-9 to 1.times.10.sup.-2 cm.sup.3 per cm.sup.3 of ink, whereby defects in images such as blank areas on images, fluctuations in dot diameter and the disturbed shape of dots are not generated to give a prominent effect and wherein the total volume of the particulate matter existing in 1 cm.sup.3 of the ink is adjusted to 3.5.times.10.sup.-6 or less, whereby ink which is stable even after long-term use can be obtained and change in amount of ink at jetting is slight, as well as defects in images can be prevented.
摘要:
A process for separating 2,6-dimethylnaphthalene form a 2,6-dimethylnaphthalene-containing mixture which comprises mixing said mixture with 2,4,7-trinitro-9-fluorenone to thereby form a complex, separating a solid matter containing said complex and decomposing the solid matter containing the same to thereby separate and collect an oil rich in the 2,6-dimethylnaphthalene. According to this process, 2,6-dimethylnaphthalene can be readily separated at a high selectivity. Further, the 2,4,7-trinitro-9-fluorenone can be readily recovered and reused as such.
