摘要：The present invention relates to novel dyeing assistant preparations

comprising, as component (a), at least one amine oxide of the formula ##STR1## in whichR is an aliphatic radical having 8 to 24 carbon atoms and

R.sub.1 is an aliphatic radical which is unsubstituted or substituted by hydroxyl and has1 to 24 carbon atoms, preferably 1 to 6 carbon atoms,

as component (b), at least one compound of the formula

R.sub.2 --U--(R.sub.3 - -O).sub.m --W (2),

in which

R.sub.2 is an aliphatic radical having 8 to 24 carbon atoms,

R.sub. 3 is alkylene having 2 to 4 carbon atoms,

U is --O-- or ##STR2## in which Z is a direct bond, (R.sub.3 --O)).sub.r or C.sub.1 -C.sub.6 alkylene and

W.sub.1 is hydrogen or C.sub.1 -C.sub. 6 alkyl which is unsubstituted or substituted byhydroxyl, carboxyl, isocyanato, phenyl, benzyloxymethylene or phenethyloxymethylene,

m and r independently of one another are a number from 2 to 25,

(R.sub.3 --O).sub.m is m identical or different radicals (R.sub.3 --O) and

(R.sub.3 --O).sub.r is r identical or different radicals (R.sub.3 --O), and

W is hydrogen or C.sub.1 -C. sub.6 alkyl which is unsubstituted or substituted byhydroxyl, carboxyl, isocyanato, phenyl, benzyloxymethylene or phenethyloxymethylene,and, as component (c), an organic solvent, and to their use as dyeing assistants for dyeingwool.
