Abstract
1441522 Monoazo dyestuffs BAYER AG 13 Feb 1974 [14 Feb 1973] 6532/74 Heading C4P Novel monoazo dyestuffs of the formula (in which R 1 is an alkoxy group ortho or para to the azo group; R 2 , R 3 , R 4 , and R 5 are independently H, halogen, alkyl, alkoxy, or optionally substituted aryl; Y is H, SO 3 H, NO 2 or optionally substituted sulphamoyl; n=0 or 1 provided that the total number of SO 3 H groups is 1 and that the SO 3 H group is not attached to the benzene ring bearing R 4 if Y denotes a sulphamoyl group) are prepared by alkylating the dyes corresponding to the formula above where R 1 is OH, alternatively by reacting the corresponding p-aminoazobenzene with the appropriate orthohalonitrobenzene compound. The dyes are used for dyeing and printing natural or synthetic polyamide materials.
