    摘要： Chromogenic compounds for use in pressure sensitive recording sheets represented by the formula: ##SPC1##Are disclosed, wherein R.sub.1 and R.sub.2 are independently, hydrogen substituted or unsubstituted lower alkyl, aliphatic acyl, phenyl substituted aliphatic acyl, benzoyl, aralky, phenyl (the benzene nuclei of those substituents may be further substituted by chlorine, bromine, lower alkyl, lower alkoxy or nitro), allyl, allyl substituted by lower alkyl or phenyl, propargyl, or propargyl substituted by lower alkyl or a phenyl; R.sub.3 and R.sub.4 are independently lower alkyl, benzyl and phenyl (the benzene nuclei or those substiutents may be further substituted by chlorine, bromine, lower alkyl or lower alkoxy), either R.sub.1 or R.sub.2 being other than hydrogen when R.sub.3 and R.sub.4 are both ethyl groups.

    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.
