Abstract: The invention relates to solid dye formulations which, in addition to containing at least one anionic dye, at least one anionic dispersant, a non-ionic emulsifier and optionally further ingredients, contains 0.1 to 10% by weight, based on the final formulation, of a quaternary ammonium salt of the formula I ##STR1## wherein R.sub.1 is a C.sub.8 -C.sub.20 alkyl or C.sub.8 -C.sub.20 alkenyl group, each of R.sub.2, R.sub.3 and R.sub.4 independently of one another is a C.sub.1 -C.sub.4 alkyl group, and An.sup..crclbar. is an anion.Such formulations, which have good cold water solubility, are suitable for dyeing or printing textile material e.g. of wool or polyamide.
