Abstract
Highly concentrated solutions of coupling components of the ice-color dyeing technique had been found which possess a very good stability to storage and can readily be used for the preparation of diluted aqueous bottoming baths of the ice-color technique; these novel solutions contain the coupling component, water, sodium-or potassium hydroxide, and are characterized by the imperative content of diethylene-glycol or a content of a mixture of diethylene-glycol and ethylene-glycol or propylene-glycol or both.
