A batchwise process for dyeing hydrophobic fibres at 110.degree. C. to 135.degree. C. with a disperse dye in the presence of an adduct of an average of 1 to 4 molar proportions of ethylene oxide, propylene oxide or styrene oxide or a combination of these oxides with 1 molar proportion of a phenol compound having the formula ##STR1## in which n is a number from 1 to 4, R.sub.1 is hydrogen, chlorine an alkyl group with 1 to 8 carbon atoms, an alkoxy group with 1 to 8 carbon atoms or an alkenyl group with 2 to 8 carbon atoms. R.sub.2 is an alkyl group wtih 1 to 8 carbon atoms, an alkenyl group with 2 to 8 carbon atoms, a cyclo-alkyl group with 5 to 8 carbon atoms which is optionally substituted by one or more alkyl groups containing 1 to 4 carbon atoms, a cycloalkyl group with 5 to 8 carbon atoms, an aralkyl group containing 7 to 9 carbon atoms which is optionally substituted by an alkyl group with 1 to 4 carbon atoms in the aromatic ring, an aralkenyl group containing 2 or 3 carbon atoms in the alkenyl part, a hydroxymethyl or a COOR.sub.3 group in which R.sub.3 is phenyl optionally substituted by alkyl having 1 to 4 carbon atoms, aryloxyalkyl in which the alkyl part contains 2 or 3 carbon atoms and the aryl part is optionally substituted by one or more chlorine or one or more alkyl groups with 1 to 4 carbon atoms, or an aralkyl group with 7 to 9 carbon toms or a phenyl-hydroxyethyl group and with the proviso that (a) the total number of aliphatic carbon atoms in (R.sub.1).sub.n-1 +R.sup.2 does not exceed 8 (b) the total number of aliphatic carbon atoms in (R.sub.1).sub.n-1 when R.sup.2 is alicyclic or aralkyl is 2, (c) when n is 1 and R.sub.2 is alkyl, the alkyl group contains at least 2 carbon atoms and (d) when the adduct is derived from styrene oxide, R.sub.2 can be hydrogen or chlorine, obtaining on said fibres level dyeings with an outstanding color yield.
