Procedure

In the same manner as in Example 1, 1 g of C.I. Basic Red 14 (commercial name: Aizen Cathilon Red 4GH, made by Hodogaya Chem. Ind., Col, Ltd.) and 1 g of sodium dodecylbenzenesulfonate were reacted to obtain about 1.6 g of a dark reddish purple tar-like captioned hydrophobic cationic dye. The hydrophobic cationic dye was placed in a water-toluene phase and shaken, whereupon the dye mostly remained in the toluene phase. This reveals that the substitution with the organic anion contributes to drastically improved miscibility with the organic solvent.
