Abstract

PURPOSE:To produce the title dye which has excellent solubility in water and does not cause clogging of a nozzle of an ink jet printer, by adding LiCl to an aq.soln. of a water-soluble dye contg. a lithium sulfonate group to effect salting out. CONSTITUTION:The pH of an aq. soln. contd. 2-40 wt% water-soluble dye contg. sodium sulfonate group (e.g. C.I. Direct Black-19) is adjusted to 6-10, and the ag. soln. is heated at 50-90 deg.C. 3-10wt% (based on the quantity of the aq. soln.) LiCl is added to the aq. soln. to effect salting out. The resulting water-soluble dye contg. a lithium solfonate group is recovered by filtration and washed with an alcohol to remove LiCl.

Conventionally, methods for producing water-soluble dyes having lithium sulfonate groups (hereinafter abbreviated as "lithium type dyes") include the acid precipitation method, or ', n) Desodiumization of IJium type dyes using ion exchange resins. A known method is to convert the dye into sulfonic acid using an ion exchange resin method, neutralize it with lithium hydroxide, and remove it by salting out or crystallization.

However, in the case of the acid precipitation method, the dye is precipitated in many cases, and the permeability of the precipitated dye is generally extremely poor, so it takes a long time to separate, and the acid contained in the dye wet cake after 1 minute M is In many cases, large amounts of expensive lithium hydroxide are required for neutralization. In addition, since it is operated under strong acidity, there are significant restrictions on the materials of the equipment.

In addition, when using an ion exchange resin, the sodium type dye develops in a column filled with the ion exchange resin and is desodiumized to become a sulfonic acid, resulting in an extremely low solubility. The dye may precipitate and cause blockage. In order to avoid this, it is necessary to develop with a large amount of water, but the resulting dye concentration is significantly diluted.
