摘要:
Fluid formulations of oxidation dyes, which are obtained by oxidizing a compound of the general formula I ##STR1## where R.sup.1 is unsubstituted or hydroxy-, C.sub.1 -C.sub.8 -alkoxy- or C.sub.1 -C.sub.8 -alkanoyloxy-substituted C.sub.2 -C.sub.13 -alkyl,R.sup.2 is hydrogen or unsubstituted or hydroxy- or C.sub.1 -C.sub.8 -alkoxy-substituted C.sub.1 -C.sub.13 -alkyl andX is hydroxyl, amino or ##STR2## in an organic solvent, are particularly suitable for dyeing mineral oil products, fats and waxes.
摘要:
Polyazo dyes which in the form of the free acids correspond to the general formula I ##STR1## where D is the radical of a diazo component, or a radical of the formula ##STR2## n is 0 or 1, R.sup.1 is hydrogen, chlorine, bromine, methyl, ethyl, methoxy, ethoxy, carboxyl, trifluoromethyl, methylsulfonyl, ethylsulfonyl or hydroxysulfonyl,R.sup.2 is hydrogen, chlorine, bromine, methyl, methoxy, carbamyl or sulfamyl,one X is hydroxyl and the other X is amino, Y is hydrogen or hydroxysulfonyl, but at least one Y is hydroxysulfonyl andZ is a radical of the formula ##STR3##
摘要:
Dye mixtures containing dyes of the formula I ##STR1## where X is hydrogen, chlorine or bromine,R.sup.1 is hydrogen, methoxy, ethoxy or phenoxy,R.sup.2 is hydrogen, methyl, ethyl, n-propyl or i-propyl andR is ##STR2## where R.sup.3 is C.sub.1 -C.sub.5 -alkyl, allyl, methallyl, crotonyl, prenyl or benzyl,R.sup.4 is unsubstituted or phenyl- or phenoxy-substituted straight-chain or branched C.sub.1 -C.sub.8 -alkyl which may be interrupted by 1, 2 or 3 0 atoms, or is C.sub.3 -C.sub.5 -alkenyl, unsubstituted or chlorine-, bromine-, C.sub.1 -C.sub.4 -alkyl- or C.sub.1 -C.sub.4 -alkoxy-substituted phenyl or benzyl,the mixtures containing not less than 40% of dyeswherein R is ##STR3## or NHC.sub.2 H.sub.4 CN, from 0 to 20% of one or more dyes wherein R is ##STR4## and from 10 to 60% of one or more dyes wherein R is ##STR5##
