    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.
