Abstract

287,609. British Dyestuffs Corporation, Ltd., and Baddiley, J. Dec. 10, 1926. Addition to 283,319. Seconda.ry disazo dyes.-The secondary disazo dyes, other than those used in the parent Specifification, obtained by coupling the diazo compound of a sulphonated or carboxylated p-nitroarylamine with one of the usual middle components, rediazotizing, and coupling with an aminonaphthol sulphonic acid or an N-derivative thereof (except the 2 : 8-aminonaphthol sulphonic acids and their derivatives) are used for dyeing regenerated cellulose materials, e.g. viscose silk, in level shades. The dyestuffs obtained by reduction of the nitro group may also be used, the latter being diazotized on the fibre, if desired, and developed with the usual developers. The shades obtained on viscose silk with dyestuffs from the following components, the end component being coupled alkaline, are tabulated :-p-nitraniline-o-sulphonic acid, m-amino-p-cresolmethylether, and H-acid, acetyl-H-acid, glycine of 2: 5 : 7-acid, 1 : 8 : 4- acid, or 1 : 8-aminonaphthol-2 : 4-disulphonic acid ; p-nitraniline-o-sulphonic acid, m-toluidine, p-xylidine or Cleves acid, and 1 : 8 : 4-acid ; 5- nitro-2-aminobenzoic acid or 2 : 4-dinitraniline-6- sulphonic acid, m-amino-p-cresolmethylether, and 1 : 8 : 4-acid; and the reduced dyestuffs from pnitraniline-o-sulphonic acid: m-amino-p-cresolmethylether and H-a,cid or 1 : 8 : 4-acid. Specifications 19743/92, 4767/09. 4768/09, 11364/09, and 23992/09 are referred to.
