| abstract | 14,448. Levinstein, H., Baddiley, J., and Levinstein Ltd. June 15. Samples furnished. Mono-, dis-, and tris-azo dyes are produced by combining diazo, tetrazo, diazoazo, or diazodisazo compounds with the glycine esters of heteronuclear aminonaphthol sulphonic acids described in Specification 11,877/10. The following combinations are specified :-a monoazo dye from oanisidine and the ethyl ester of the glycine of 1-amino -8-naphthol -3 : 6-disulphonic acid ; the diazo compounds of #-naphthylamine, picramic acid, p-nitro-o-aminophenol, or p-aminoacetanilide are also specified as components ; a mixed disazo dye from tetrazotized benzidine, salicylic acid, and the ethyl ester of the glycine of 2-amino -8- naphthol -6-sulphonic acid ; benzidine may be replaced by tolidine or dianisidine, and the other components by 2-naphthol -6-sulphonic acid or the glycine esters of 2 : 5 : 7-aminonaphthol sulphnnic acid or 1 : 8 : 3 : 6-aminonaphthol disulphonic acid ; secondary disazo dyes from p-aminoacetanilide, 1 : 6- or 1 : 7-naphthylamine sulphonic acid, or a mixture thereof, and the ethyl ester of the glycine of 2-amino -5-naphthol -7-sulphonic acid, and trisazo dyes from p-aminoacetanilide, 1 :6- or 1 : 7-naphthylamine sulphonic acid or a mixture thereof, a second molecule of such a component, and the ethyl ester of the glycine of 2-amino -5-naphthol -7-sulphonic acid ; a secondary disazo dye from 1-amino -8-naphthol -3 : 6-disulphonic acid, alpha-naphthylamine, and the ethyl ester of the glycine of 2-amino -5-naphthol -7-sulphonic acid ; the aminoazo compounds from 2- naphthylamine -3 :6-disulphonic acid and p-xylidine, and from sulpbanilic acid and alpha-naphthylamine, and the aminodisazo compound from metanilic acid, alpha-naphthylamine, and Cleve's acid, are also specified as components. |
