Abstract

6080. Farbwerke vorm. Meister, Lucius, & Br³ning. March 13, 1911, [Convention date]. Samples furnished. Arylnaphthylamine sulphonic acids are obtained by condensing p-phenylenediamine, benzidine, or their homologues or substitution products, with naphthylamine sulphonic acids, such as the 1:7-, 1:8-, or 1:2-naphthylamine sulphonic acids or 1:3:6-naphthylamine disulphonic acids; the condensation is effected by heating the parent materials, with or without solvents or suspending-agents. The condensation of benzidine with 1:7-naphthylamine sulphonic acid is described in an example. The Specification as open to inspection under Section 91 (3) (a) describes also the use of paradiamines in general, and of naphthalenediamines, in the above-described process; this subject-matter does not appear in the Specification as accepted. Indophenols are obtained by condensing the above-described arylnaphthylamine sulphonic acids with p-nitrosophenol or a substitution product thereof, or by joint oxidation of the arylnaphthylamine sulphonic acids with paminophenol or a substitution product thereof; the product from benzidyl-1-naphthylamine-7- sulphonic acid and p-aminophenol is specified. Sulphuretted dyes are obtained by heating the above-described indophenols with alkali polysulphides in presence or not of diJuents, such as water, alcohol, or glycerine, or metallic salts, such as copper sulphate. The product obtained from the indophenol specified above dyes cotton green shades in a sulphide bath.
