Abstract

1380235 Fibre reactive water-soluble monoazo dyestuffs FARBWERKE HOECHST AG 6 Nov 1972 [5 Nov 1971] 51072/72 Heading C4P Novel dyestuffs of the formula wherein Z is -CH=CH 2 or -CH 2 CH 2 OSO 3 H, A is optionally substituted phenylene or naphthylene with the azo and amino groups ortho or para to each other or is optionally substituted pyrazolylene with the amino group in the S- position and the azo group in the 4-position, and R 1 and R 2 are hydrogen atoms or optionally substituted C 1-4 alkyl or aryl radicals, are prepared by diazotizing 2-sulpho-4-(SO 2 Z)-anilines and coupling with appropriate amines HANR 1 R 2 , preferably at a pH of 0-5. Products wherein Z is -CH 2 CH 2 OSO 3 H may be converted by warming with an aqueous alkali to products wherein Z is -CH=CH 2 . The novel dyestuffs are used for dyeing and printing natural and regenerative cellulose and natural and synthetic nitrogen-containing fibre materials in yellow to violet shades. Reference has been directed by the Comptroller to Specification 1,220,422.
