Abstract: Triaminotriarylmethane colorants are obtainable by first reacting an aluminum or iron trihalide complex of a 4,4',4''-trihalotriphenylmethyl halide with a metanilic acid, a sulfanilic acid or a beta -naphthylaminesulfonic acid and then reacting the product with one or more anilines to replace the halogen atoms located in the 4-positions. The compounds according to the invention are very useful as pigments, for example in printing inks, or for toning carbon black.

Abstract: New triarylmethane dyestuffs (I) with a sulphonated benzene ring are of formula (I). In (I) R has formula (II) or (III) R1, R2, R4, R6 and R7 are H, Me or Et, R3 is H, Me, Et or Ph and R5 is Me, Et, Ph, tolyl, methoxyphenyl or ethoxyphenyl. If R1 and R2 are not H, -NR3R4 is -NH2; if -NR3R4 is NEt2, R is not -Q-NMe-Ph (Q is o-phenylene); and if R1 and R2 are H and R is -Q-NH2 or -Q-NH-Ph, no. -NR3R4 is NH2 or -NHPh. (I) are used in printing inks or for toning C black. They are also useful in carbon paper. They are violet to greenish-blue in colour and insoluble in water. (I) can be prepd. by conventional methods, e.g. condensn. of 4,4'-aminobenzophenone with aniline or alpha-naphthylamine and sulphonation, if necessary.
