Abstract

Disazo dyes are prepared by coupling the tetrazo compounds of the diaminodiaryldialkylmethanes described in Specification 204,722, with any components, for example, naphthol- or aminonaphthol-sulphonic acids or pyrazolone sulphonic acids. The products dye wool from an acid bath in red, violet, yellow, &c. shades fast to washing, fulling, and light. Examples are given of the production of dyestuffs from diamino-di-o-tolyldimethylmethane and 1-naphthol-5-sulphonic acid, diaminodiphenyldimethylmethane and 1-(2-chlor-5-sulphophenyl)-3-methyl-5-pyrazolone, diaminodiphenylmethylethylmethane and 1-amino-8-naphthol-4-sulphonic acid.
