摘要：
Liquid finished formulations which are stable to storage and hydrolysis and are based on the lyotropic liquid crystal aqueous phase of the dyestuff of the formula ##STR1## in water in a concentration of 12-35% at room temperature are outstandingly suitable for the preparation of dyebaths and printing pastes for dyeing cotton, wool, regenerated cellulose, paper and leather.
