Abstract

Azo dyes are formed by coupling (1) diazotized 3-n-dodecyloxyaniline with 8-amino -5, 7- disulpho -1- naphthol, (2) 1 mol. of diazotized m-phenylene-diamine with two mols. of 8-amino -5-sulphol -1- naphthol, (3) diazotized 3-n-dodecyloxyaniline with 8-acetylamino -5- sulpho -1-naphthol, and (4) diazotized p-methoxyaniline with 1-[p-(p1-t-butylphenoxy)-phenyl] -3- {a -[p-t-butylphenoxy] propionylamino} -5- pyrazolone. Specifications 524,154, 524,554, 524,555, 541,589, 547,064, 586,211, 598,174, 599,377, 617,247, 627,814, 649,660, 680,488, 737,104 and 800,108 are referred to.
