Abstract
PURPOSE: To manufacture a solution of a diphenylmethane derivative dye used in pressure-sensitive copying papers with high efficiency by causing an acid water containing sulfinic acid and a specific compound to react in a hydrophobic organic solvent.
CONSTITUTION: A sulfinic acid of the formula I (wherein R5 is alkyl, aralkyl, aryl, etc.) is dissolved in an aqueous medium to obtain an aqueous acid sulfinic acid solution of pH 7 or less. Then, the aqueous acid solution is mixed with a compound of the formula II [wherein R1, R2, R3, and R4 are alkyl groups which may be substituted with halogen, alkoxy, and cyano group, X and Y are halogen, alkyl, alkoxy, etc., and Z is a substituent of formulas IIIWV (wherein A, B, C, and D are H or hydrocarbon groups which may have one or more hetero atoms)], dissolved in a hydrophobic organic solvent, such as phthalic ester or salicylic ester, and then reacted at 10W80°C to obtain a solution containing a diphenylmethane derivative of the formula VI.
