Abstract

The invention relates to the use of water-soluble compounds obtained by esterifying alkylene oxide adducts on alcohols having 10 to 24 C atoms with carboxylic acids having up to 22 C atoms and carrying 1 to 6 carboxyl groups as preparation agents for dyestuffs which are insoluble to sparingly soluble in water and preparations which contain a dyestuff having a particle size of less than about 5 .mu.m and one of the preparation agents mentioned.
