When using liquid hydrocarbons, stable emulsions are easily obtained at the same time act as a thickener, since the setting accelerators have emulsifying properties. By selecting the setting accelerators, one also has the option of producing emulsions of a certain type. For example, the condensation products of carboxylic acids with 8 to 14 carbon atoms are usually oil-in-water -Emulsions with which the higher carboxylic acids obtain water-in-oil emulsions in the production of multi-color prints, by alternating oil-in-water and water-in-oil emulsions for successive colors, whereby a particularly sharp print image is achieved. :, "· ■,. ■

The material impregnated or printed with dye and fixing accelerator is treated with dry heat after the usual drying to fix the dye. This can be done, for example, by means of infrared radiation or with the aid of heated rollers or metal baths. However, the material is preferably treated with hot air or superheated steam. For a complete fix the dye be enough temperatures around 15O ⁰ C, but it is also possible at higher tem-, temperatures to work for example in I70 to l80 ° C unless the estate, these temperatures can tolerate, but brings generally not better result. The treatment times are 5 to 6 ^{at 150 ° C}
