Abstract

308,958. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Dec. 30, 1927. Trisazo dyes ame obtained by diazotizing an aminoazr compound, coupling with a 1-amino-2- r,aphibolet,her or a derivative thereof, again diazotizing and coupling with an acidylated 1- amino-8-hydroxynaplithalene sulphonic acid; the third cnapling may be effected in the presence of pyridine. Dyes are specified from the following sets of components :-p-sulphanilic acid, otoluidine, 1 - amino - 2 - naphtholethylether - 6 - sulplionic acid and N -benzoyl-H-acid; aminoazotoluene-sulphonic acid, 1-amino-2-naphtholethlether-6.sn]phonio acid and N-o-chlorbenzoyl-H- acid: the amino azo compound obtained hy diazotizing 2-naphthy!am]r)e-8-sn!phonic acid. couphaR with anirne-M-methanesuIphonio acid and hydroly7ing, 1-amino.2-naphtholethylether-6-sulphonic acid and N-acetyl-H-acid; 2-naphthvlamine-8- su]pbonic acid, s-xylidine, l-amino-2-napbtholethylether-6.-eulphonic acid and N-acetyl- or ochlorbenzoyl-H-acid or N-benzoyl-or-o-chlorbenzoyl-K-acid (prepared by the action of benzoylchloride or o-chlorbenzoylchlonide respectively on K-acid).
