Abstract

Use of carbohydrate compounds as auxiliaries for dyeing and printing fiber materials Use of carbohydrate compounds of the formula (1) EQU Z--G--T--R.sup.1.sub.n (1) in which PA0 Z is the radical of a carbohydrate from the series consisting of mono-, di- or oligosaccharides or of a sugar alcohol, the free valency being on a carbon atom; PA0 G is a bridge member from the series consisting of --O--, --NR.sup.5 --, --O--CO--, --NR.sup.5 --CO-- and --NR.sup.5 --SO.sub.2 --, in which R.sup.5 is hydrogen or C.sub.1 ---C.sub.4 -alkyl, which can be substituted by 1 to 4 radicals from the series consisting of hydroxyl, sulfo, sulfato or carboxyl; PA0 T is a C.sub.4 -C.sub.30 -aliphatic, cycloaliphatic or oiefinic hydrocarbon radical, or is C.sub.6 -C.sub.10 -aryl or is C.sub.6 -C.sub.10 -aryl-C.sub.1 -C.sub.4 alkylene; PA0 R.sup.1 is hydroxyl, carboxyl, cyano, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, sulfo, C.sub.1 -C.sub.10 -alkylsulfonyl, aminosulfonyl, C.sub.1 -C.sub.10 -alkylaminosulfonyl or C.sub.6 -C.sub.10 -arylaminosulfonyl, C.sub.1 -C.sub.10 -alkylcarbonyl, ureido, C.sub.1 -C.sub.10 -alkylcarbonylamino, C.sub.1 -C.sub.10 -alkoxycarbonyl or aminocarbonyl, where the alkyl or…
