Abstract

20,608. Newton, P. A., [Farbenfabriken vorm. F. Bayer & Co.]. Sept. 18. Samples furnished. Trisazo dyes are obtained by combining tetrazolized p-diaminodiphenylamine or a homologue thereof with one molecule of 2:5:7- or 2:8:6- aminonaphthol sulphonic acid, diazotizing the intermediate product so obtained, and combining the resulting tetrazo body with two molecules of m-aminophenylglycine or a homologue thereof, or one molecule of such a glycine and one molecule of another component. Products are specified from:-p-diaminodiphenylamine, 2:8:6-acid, and m-aminophenylglycine; p-diaminophenyltolylamine, 2:5:7-acid, m-aminophenylglycine, and resorcin. The products dye cotton black shades, which may be aftertreated with formaldehyde.
