    摘要: A hydrophobic organic solvent containing a compound of the formula ##STR1## is dispersed and emulsified in an aqueous medium containing a sulfinic acid of the formulaR.sub.5 --SO.sub.2 H (I)and serving as an aqueous medium for preparing microcapsules to react the compounds of the formulae (I) and (II) and synthesize a diarylmethane derivative of the formula ##STR2## while encapsulating oily droplets of the resulting hydrophobic organic solvent solution of the diarylmethane derivative. Colorless chromogenic materials can be synthesized and encapsulated at the same time by this process.
