Dyestuff Formulations Abstract Formulations for dyeing polyesters and polyamides, the dyestuff component of which does not tend to crystallise in the dyebath and the effluents of which can be readily degraded biologically, are obtained in an inexpensive manner when those organophilic dyestuffs which have melting points below 140°C, preferably below 100°C, are used and these dyestuffs are homo- geneously mixed with emulsifying polar/non-polar compounds, such as, for example, fatty sulphates and sulphonates, without expensive fine comminution processes.
