Abstract

1,255,395. Reactive monoazo dyes. MERCK PATENT G.m.b.H. 17 Feb., 1969 [9 March, 1968], No. 8520/69. Heading C4P. [Also in Division D1] Reactive monoazo dyes, used to colour cellulose with formation of a covalent bond to give pH sensitive materials (see Division D1), of formula wherein the rings are benzene or naphthalene nuclei, one of R<SP>1</SP> to R<SP>7</SP> is a HO.SO 2 .O.CH 2 CH 2 .- SO 2 - or HO.SO 2 .O.CH 2 CH 2 SO 2 .N(CH 3 )- group, another is a COOH or SO 3 H group, one of R<SP>1</SP> to R<SP>3</SP> is an amino group which may be alkyl-, phenyl- or benzyl-substituted or a hydroxy group and the remaining R<SP>1</SP> to R<SP>7</SP> substituents are H, Cl, Br, OH, NO 2 , SO 3 H or C 1-4 alkyl or alkoxy groups. They are prepared by azo coupling using appropriate components.
