摘要：
PROBLEM TO BE SOLVED: To provide a method for manufacturing a lithium salt pigment for data recording from a sodium salt pigment, wherein a conversion efficiency of a cationic species is excellent.
SOLUTION: This manufacturing method comprises steps wherein (a) a water-soluble pigment having an -SO
3 Na group and a hydrophobic amine are contacted with an acid in the presence of water and a hydrophobic organic solvent to obtain and separate a hydrophobic organic solvent solution containing a hydrophobic amine salt of a poorly water-soluble pigment having an -SO
3 H group and an aqueous solution containing an Na salt of the above acid, (b) the separated hydrophobic organic solvent solution containing the hydrophobic amine salt of the poorly water-soluble pigment having the -SO
3 H group is treated with lithium hydroxide in the presence of water to obtain an aqueous solution containing a pigment having an SO
3 Li group and the hydrophobic organic solvent solution containing the hydrophobic amine salt, and (c) the aqueous solution containing the pigment having the SO
3 Li group and the hydrophobic organic solvent solution containing the hydrophobic amine salt are separated.
