A process for producing solutions of salts of lower aliphatic carboxylic acids of cationic dyestuffs which consists essentially of converting the halide, especially the chloride, of a cationic dyestuff into the salt of a lower aliphatic carboxylic acid by reacting the halide with the corresponding carboxylic acid in the presence of an epoxide compound having a maximum of 12 carbon atoms.
