Abstract

1,159,122. Reactive dyestuffs. GAF CORP. 23 Aug., 1966 [21 Oct., 1965], No. 37810/66. Heading C4P. The invention comprises monoazodyestuffs of general formula A-N=N-B having at least one α,#-dihaloacryloylamino group attached to A and NB and wherein A is a benzene nucleus which may contain a sulphonic acid and/or an OH group, and B is an N-phenyl-3-methyl-5- pyrazolone which may be substituted by halogen, sulphonic or carbonylic acid on the phenyl nucleus, or is a naphthol optionally substituted by one or two sulphonic acid groups but not pto the OH group and/or an acylamide, carbonyl or OH group, the dyestuffs containing at least one sulphonic acid group in A or B. The dyestuffs are prepared by introducing an α,#- dihaloacryloylamino group into a dyestuff intermediate or an azo dye by acylation of an amino group and converting the intermediate into a dyestuff by diazotization and coupling. The dyes obtained dye cellulosic materials e.g. cotton, linen, wood and paper in all shades.
