Abstract
Novel water-sol. monazo dyestuffs are of formula (I) in the free acid form:- (where R1 and R2 are each H, halogen, (cyclo)alkyl or aryl R3 is H, lower alkyl, acyl (cyclo)alkoxycarbonyl, aryloxy-carbonyl or arylsulphonyl -OR3 is the 2- or 4-pos. w.r.t. the azo radical). Used as reddish-yellow dyes for synthetic polyamide e.g. nylon 6.6, 6 or 11, with high fastness to wet treatments and light. (I) are esp. suitable for the dyeing of nylons having differential dyeing properties, such that large contracts may be obtd. e.g. polyamide carpets.
