Abstract
Abstract A liquid dye preparation comprising an aqueous solution containing at least 0.5% by weight of a water-soluble anionic dye and at least 0.1% by weight of a surfactant of the formula: ##STR1## wherein R represents a non-ionic substituent, m represents an integer from 0 to 3, X represents a divalent bridging atom or group, Y represents a C 2-4 alkylene radical, n represents an integer of at least 2, and Z represents hydrogen, akyl, sulpho or phosphino.
