Abstract: The increasingly specific requirements regarding the properties of pigments, particularly in the printing sector, has made the development of specific dispersion, emulsification and coupling assistants necessary. According to the invention, novel substances which are suitable for a very wide variety of areas of application in the field of surfactants and can be employed, for example, in the preparation of azo pigments for improving the coloristic properties are obtained from oxyalkylates of aliphatic or cyclic, primarily primary diamines or polyamines or from block polymers (containing recurring structural units of the abovementioned oxyalkylate type) produced by prior linking of such oxyalkylates with dicarboxylic acids, by esterification of the terminal hydroxyl groups in these aminooxyalkylates using fatty acids or aromatic carboxylic acids and/or resin acids, and optionally subsequently reacting any free hydroxyl groups still present with dicarboxylic acids and sulphite to give the corresponding monoesters (containing anionic radicals).

Abstract: According to the invention, addition of one or more surfactants having a cloud point in aqueous solution to an aqueous suspension of an azo disperse dye gives after the isolation of the dye at a temperature above the cloud point aqueous press cakes containing a large amount of this dye. The direct processing of press cakes as obtained for example after the synthesis and isolation of azo disperse dyes to practical dispersions for use requires a minimum dye content in the press cakes. The minimum content is frequently not obtained when conventional methods of isolation are used, so that it is necessary to proceed via the indirect route of drying to obtain powders and redispersing the powders. By using the process according to the invention it is possible to cut out the costly indirect route or, if desired, to reduce the expense of drying to obtain powders by an appreciable margin.
