摘要:
A substantially colorless bisfluoran chromogenic material having the structural formula ##STR1## wherein R.sup.1 and R.sup.2 each represent an alkyl group;X and Y each represent a hydrogen atom, a halogen atom, an hydroxyl group, an alkyl group, a nitro group, an amino group, an acyl group, or a carboalkoxy group;Z represents an oxy radical, a carbonyl group, an alkylene group, an alkylidene group, a sulfonyl group, or a thio radical; andn represents an integer from 0 to 1.The bisfluoran compounds are produced by reacting a 4-dialkylamino-2-hydroxy-2'-carboxybenzophenone with a diphenol wherein the diphenol is unsubstituted in at least one of the positions ortho to an hydroxyl group in each of the phenyl rings. The bisfluorans are used in pressure-sensitive copy systems comprising a support bearing microcapsules containing the bisfluorans, alone, or in combination with other color-forming materials.

摘要:
A substantially colorless dilactone chromogenic material having the structural formula ##SPC1##And ##SPC2##WhereinR represents an alkyl group, an aryl group, an aralkyl group, an acyl group or an aroyl group; andX represents a hydrogen atom, a halogen atom, an alkyl group or a nitro group.The dilactone compounds are produced from precursor compounds that are formed by reacting pyromellitic dianhydride with a resorcinol having at least the fourth or the sixth position unsubstituted, in the presence of a dehydrating agent to form xanthyl derivatives of isophthalic and terephthalic acid. These precursors are then further reacted to form the dilactones. The dilactones are used in pressure-sensitive copy systems comprising a support bearing microcapsules containing the dilactones, alone, or in combination with other chromogenic materials.
