Abstract

28,716. Newton, P. A., [Farbenfabriken vorm. F. Bayer & Co.]. Dec. 8. Monoazo dyes are obtained by combining the diazo compounds of o-aminophenol sulphonic acids or derivatives thereof with 1:3-dioxyquinoline. The specified components are :-2-aminophenol-4- sulphonic acid, 4-chlor-2-aminophenol-6 sulphonic acid, 6-nitro-2-aminophenol-4-sulphonic acid, 6- sulpho-2-aminophenol-4 carboxylic acid. The products dye wool yellow to red shades, becoming red to bordeaux on chroming. Specification 11,205/05 is referred to. 6-Sulpho-2-aminophenol-4-carboxylic acid is obtained by sulphonating m-amino-p-oxybenzoic acid.
