Abstract

New 3-[4-(disubstituted amino)phenyl]- or 3-[(9-julolidinyl)]-3-(diphenylamino)phthalides of formula <IMAGE> in which the symbols are defined in Claim 1, are prepared by reacting benzoic acids substituted by (Q)n and, in position 2, by -COZ, with the corresponding diarylamine, in the presence of a C2-C5 alkanoic acid, a base, or else with the diarylamine in the presence of a base after conversion into cyclic lactone chloride. If desired, certain salts of the compounds in which (Q)n = COOH are prepared. The compounds obtained can be employed as colour-forming agents in pressure-sensitive systems and thermal marking systems. [GB1564559A]
