Abstract
Abstract An aqueous liquid dye composition containing 10 to 50 parts by weight of C.I. Reactive Blue 19, 1 to 40 parts by weight of a condensation product of formaldehyde with naphthalenesulfonic acid which may be alkylated, 0.1 to 10 parts by weight of a nonionic surfactant having an HLB of 9 to 20, and 20 to 80 parts by weight of water. This liquid dye composition has a good storage stability, and shows a sufficient solubility in an aqueous alkali liquor so that it is particularly suitable for dyeing cellulosic fibers by a one-bath pad-batch method.
