Abstract
520,101. Dyes. GEIGY AKT.-GES., J. R. Oct. 26, 1938, No. 30958. Convention date, Oct. 27, 1937, [Class 2 (iii)] Acid monoazo dyes are made by coupling diazotised monoaminodiphenylether sulphonic acids or monoaminophenoxydiphenylether sulphonic acids with 1-phenyl-3-methyl-5-pyrazolones or 1-phenyl-5-pyrazolone-3-carboxylic acids or their esters, chlorinated in the phenyl radicals. They yield yellow shades on wool and silk. In examples, dyes from the following components are described : 31;5'-dimethyl- 2-aminodiphenylether-4-sulphonic acid, 4<SP>1</SP>- phenoxy-2-aminodiphenylether-4-sulphonic acid 2' - methyl - 2-aminodiphenylether - 4-sulphonic acid, 2<SP>1</SP>:4<SP>1</SP>-dichloro-6<SP>1</SP>-methyl-2-aminodiphenylether-4-sulphonic acid, 4<SP>1</SP>-isoamyl or 41-phenyl or 4<SP>1</SP>-chloro-2-aminodiphenylether-4-sulphonic acid, the products obtained by the condensation of p-nitrochlorbenzene sulphonic acids with aromatic hydroxy compounds and subsequent reduction; 1-(31-chloro- or 3<SP>1</SP>-4<SP>1</SP>-dichloro-or 3<SP>1</SP>:4<SP>1</SP>:5<SP>1</SP> - trichlorophenyl) - 3 - methyl-5-pyrazolone ; the pyrazolones from 2:4-, 3:5- or 2:4:5- trichloroaniline. The Specification as open to inspection under Sect. 91 comprises the use of 4<SP>1</SP>-phenylazo-2- aminodiphenylether-4-sulphonic acid as diazo component. This subject-matter does not appear in the Specification as accepted.
