    Abstract: New heterocyclic methylene cpds. are of formula (I), X = -C(R3(R4)-, -N(R5)-C(=O)- or -C(R6)=C(R7)-, (II), (III), (IV) or (V), R1 = H, C1, or Br, R2 = 1-4C alkyl (opt. substd. by OH, CN, carbo -1-8C alkoxy, carbamoyl or N,N-di-1-4C alkylcarbamoyl, R3 and R4 or 1-4C alkyl, R9 = H, 1-4C alkyl, 1-4C alkoxy, phenyl-1-4C alkoxy, N-phenyl-N-1-4C alkylamino, pyrrolidino, piperidino, morpholino or N,N-di-1-4C alkylamino (in which the alkyl gps. may be substd. by phenyl CN, or OH), R10 and R11 independently = H, C1, Br, 1-4C alkoxy, or 1-4C alkoxycarbonyl, R12 and R13 independently = CN 2-5C alkanoyl, benzoyl (opt. substd. by 1-4C alkoxy, or N,N-di-1-4C alkylamino) carbonyl-1-4C alkoxy, or -CO-N(R14R15), R14 = H, 1-4C alkyl benzyl or phenyl (opt. substd. by C1 and/or 1-4C alkoxy, R15 = H or 1-4C alkyl, R16 = 1-4C alkyl, n = 1 or 2, R = H, 1-4C alkyl or a -CH2-CH2- or (CH2)3- gp. attached to the ortho-C atom, or -C(R8)(R12)(R13) = a barbituric acid radical). USE/ADVANTAGE - (I) are used in thermographic and carbonless copying systems. They develop intensive colours with good light fastness in the presence of acids or acidic materials.

    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.
