Abstract:
Water-insoluble azo-dyestuffs of the formula
said compounds being suitable for the dyeing or printing of synthetic fibrous materials, such as fibrous materials of celluloseacetates, polyamides, polyurethanes, polyolefins, polycarbonates and, particularly, polyesters, the dyeings obtained on these fibres being distinguished by a very good fastness to wet processing, ironing, waste gas and light and by a very good building up.

Abstract:
Secondary etheramine salts of the general formula I wherein R is long chain alkyl, cyclohexyl or aryl, X and Y are hydrogen or methyl, but are not both methyl at the same time, n is an integer of from 1 to 20, and A is an anion with the exception of the acetate ion. These salts are used as conditioning agents for synthetic fibers.
