    Abstract: Dyeings on wool and other nitrogenous fibres are levelled using as levelling agent a composition containing (a) a compound of the formula R-[-(CnH2nO)y-A-X+]m where R is the radical of an alcohol, alkyl phenol, carboxylic acid, amine, carboxylic acid amide or mercaptan which contains 6 to 30 carbon atoms or of a polypropylene glycol ether of m.w. 1000 to 4000, A- is an anionic group, X+ is a cation, n is either 2 for all the -(CnH2nO)- groups or is 2 for at least 60% of them and 3 for the remainder, y is between 30 and 100 and m is an integer, preferably 1 or 2; and (b) a compound of the formula where R1 is an alkyl, aralkyl or resin radical of at least 10 carbon atoms, R11 is hydrogen, an alkyl radical of 1-9 carbon atoms, the same as R1 or a radical of the formula -(CnH2nO)q-H, n is as above and p or the sum of p+q is a number between 3 and 15, the ratio of (a) to (b) in the mixture being 9:1 to 1:9 by weight. Among the specified radicals R are those of oleyl alcohol, branched tridecyl alcohol, dodecylphenol, dodecyl mercaptan, stearic acid, monostearoylethylene diamine, stearic acid ethanolamide and diethanolamide and decylamine. A-is preferably the radical of an organic or inorganic polybasic acid such as sulphuric, phosphoric, phthalic, maleic, sulphoacetic or chlorosulphonic acid and X+ may be an alkali metal, unsubstituted ammonium or amine cation, especially an alkylol- or alkylamine with up to 4 carbon atoms in each alkyl group or a quaternary ammonium cation. Among specified radicals R1 are those of oleylamine, coconut oil amine, commercial dodecylanilines and nonyl-naphthylamines and abietylamine. Preferred ratios of (a) to (b) are 8:2 to 6:4 by weight. The mixture may also contain polyglycol ethers, inorganic salts, buffers and protecting substances.ALSO:Dyeings on wool and other nitrogenous fibres are levelled using as levelling agent a composition containing (a) a compound of the formula where R is the radical of an alcohol, alkyl phenol, carboxylic acid, amine, carboxylic acid amide or mercaptan which contains 6 to 30 carbon atoms or of a polypropylene glycol ether of m.w. 1000 to 4000, A- is an anionic group, X+ is a cation, n is either 2 for all the -(CnH2nO)- groups or is 2 for at least 60% of them and 3 for the remainder, y is between 30 and 100 and m is an integer, preferably 1 or 2; and (b) a compound of the formula where R1 is an alkyl, aralkyl or resin radical of at least 10 carbon atoms, R11 is hydrogen, an alkyl radical of 1-9 carbon atoms, the same as R1 or a radical of the formula -(CnH2nO)q-H, n is as above and p or the sum of p + q is a number between 3 and 15, the ratio of (a) to (b) in the mixture being 9:1 to 1:9 by weight.

The mixture may also contain polyglycol ethers, inorganic salts, buffers and protecting substances. Levelling is effected in the dyebath (preferably at pH 4 to 6) or in a separate bath using preferably 0.5-2% of active levelling agent with reference to the goods to be dyed. Suitable dyestuffs are acid, metal complex (with or without solubilizing groups or afterchroming) and especially milling dyes. Shading, i.e. adding a small amount of dyestuff to an already exhausted dyebath, may be effected without previous cooling. Examples are given of the dyeing of wool and polyamide fibres and wool/polyamide fibre blends.

    Abstract: Compounds used as levelling agents in dyeing (see Group IV (c)) and having a plurality of the same or different lactam groups, viz. butyro-, valero- or capro-lactam groups, and wherein each pair of lactam groups is connected through their nitrogen atoms by a carbon chain interrupted by one or more hetero atoms, viz. nitrogen, oxygen or sulphur atoms, the number of carbon atoms in the chain between a lactam nitrogen atom and the adjacent hetero atom being 2-6, are obtained by reacting dichlordiethyl ether or sym-dichlordiethylthioether or tri-(chlorethyl)-amine with the appropriate lactams, or by reacting polyalkylene polyamines with the appropriate lactones or by reacting sodium sulphide with a lactam substituted on the nitrogen atom by a b -chlorethyl group or by reacting di-(7-aminopropyl)-ether with the appropriate lactone. Compounds containing more than two lactam groups may also be obtained by cyanoethylating all the nitrogen atoms of a polyalkylene polyamine, then hydrogenating the product to form the corresponding polyamine and finally reacting with the lactones. The carbon atoms of the lactam group may be substituted by alkyl groups and in the case of a nitrogen hetero atom in the chain, its third linkage may bear an aliphatic chain of 1-5 carbon atoms which may be further substituted by hydroxyl, ether, nitrile, amino or lactam radicals.ALSO:In the dyeing of textile materials with vat or sulphur dyestuffs level dyeings are obtained by using, as a levelling agent, a compound having a plurality of the same or different lactam groups, viz:-butyro-, valero- or caprolactam groups, each pair of lactam groups being connected through their nitrogen atoms by a carbon chain interrupted by one or more hetero atoms, viz:-nitrogen, oxygen or sulphur atoms, and the number of carbon atoms in the chain between a lactam nitrogen atom and the adjacent hetero atom being 2-6. The carbon atoms of the lactam group may be substituted by alkyl groups and in the case of a nitrogen hetero atom in the chain its third linkage may bear an aliphatic chain of 1-5 carbon atoms which may be further substituted by hydroxyl, ether, nitrile, amino or lactam radicals. Numerous levelling agents are specified and numerous examples of dyeing are given.
