Abstract

28,677. Bloxam, A. G., [Chemische Fabrik Griesheim-Elektron]. Dec. 9. Diazo dyes are obtained by combining the tetrazo compounds of p-diamines of the diphenyl series, or mono- or di-sulphonic acids thereof containing a sulphonic group in o-position to the amino group, with one molecular proportion of 1-p- or -m-sulphophenyl-3-methyl-5-pyrazolone or 1-p- or -m-sulpho-o-tolyl-3-methyl-5-pyrazolone and one molecular proportion of a nitrom-phenylenediamine or a nitro-m-toluylenediamine. Benzidine and its mono- and di-osulphonic acids are specified as suitable diamines. The products dye cotton orange to orange-red shades. Specification 20,649/09 is referred to.
