Abstract

545,524. Dyes. MANCHESTER OXIDE CO., Ltd., CLAYTON, J. H., and BANN, B. Sept. 27, 1940, No. 14621. [Classes 2 (iii) and 15 (ii)] Monoazo dyes, specially fast to light, are produced in substance or on the fibre by coupling diazotized 3-amino-4-methoxy-5-methylphenyl ethyl sulphone (obtainable as described in Specification 544,849) with Naphthol AS/ ITR (the 4<SP>1</SP>-chloro-2<SP>1</SP>-methylanilide) or Naphthol AS/TR (the 4<SP>1</SP>-chloro-2<SP>1</SP> : 5<SP>1</SP> dimethoxyanilide) of 2 : 3-hydroxynaphthoic acid. Examples relate to the production of these dyestuffs on cotton yarn. Specifications 6379/12, [Class 2 (iii)], 17279/13, [Class 15 (ii)], and 279,146, [Class 2 (iii)], also are referred to.
