Liquid crystal phase of an azo reactive dyestuff and its use for dyeing and printing natural and synthetic substrates

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 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.
