The carrier mixture contains N-alkylphthalimides and compounds of the general formula ##STR1## in which R is C.sub.1 -C.sub.7 -alkyl; phenyl, benzyl or phenylethyl, which can be substituted by C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy or C.sub.1 -C.sub.4 -alkoxycarbonyl,

Carrier mixture for the dyeing of polyester materials:

Levelling agents for disperse dyeing of polyester: ethoxylate or

Reaction products which are prepared by sulphonation or sulphomethylation and formaldehyde condensation of compounds of the formula ##STR1## wherein R.sub.1 represents C.sub.1-4 -alkyl, and, if appropriate, subsequent conversion of the resulting sulphonic acids into their salts are used as dispersing agents.

Sulphonated mono-hydric diaryl phenol formaldehyde condensates, their

Polycondensates of phenols and formaldehyde which contain sulphonic acid groups and salts thereof bonded to the phenol either directly or via a methylene bridge are prepared by reacting a neutralized reaction product of phenols and sulphonating agents, which contains a mixture of the starting phenol, phenolsulphonic acid and bis-(hydroxyphenyl) sulphones, with formaldehyde and a bisulphite at a pH value of 4-8.

Phenol-formaldehyde condensates, their preparation and their use as

Dyeing of structures made of polyesters or cellulose esters with disperse dyestuffs is carried out in the presence of chlorinated alkylbenzenes of the general formula ##STR1## in which n=1-3 and

Process for dyeing polyester-containing materials

Process for dyeing polyester fibres of fibre mixtures containing them

Water-soluble phosphoric acid esters which are prepared from polyols and/or epoxides, in some cases polycarboxylic acids or their derivatives and phosphoric acids in the molar ratio 1:(0 to 1.5):(0.05 to 1.5), the sum of the numbers of mols of the carboxylic acids and phosphoric acids being 2/3 to 3/2 of the number of mols of the alcohols, can be used as dispersing agents, liquefaction agents, levelling agents and emulsifiers and builders in detergents.

Method of dispersing, emulsifying materials with phosphoric acid esters

In a process for dyeing synthetic polyamide fibre materials with metal-free acid dyestuffs a dye liquor is used which contains compounds of the formula ##STR1## wherein R.sub.1 represents an alkyl and/or alkenyl radical with 12-22 carbon atoms,
