The novel dyes are suitable for dyeing hydroxyl- and/or carbamoyl-containing material; on hydroxyl-containing material, such as cellulose fibers, they become fixed not only in the alkaline but also in the weakly acid to neutral range, so that they can be used together with disperse dyes for dyeing blend material composed of cellullose and polyester fibers by the dyeing methods for disperse dyes.

Abstract:
Lithium salts of anionic dyes are prepared by first converting another salt of this anionic dye in aqueous solution or suspension by means of a compound which releases calcium ions into the water-insoluble or sparingly water-soluble calcium salt of the dye, which is separated from the aqueous medium and is then converted to an aqueous suspension by treatment with lithium sulfate or lithium hydrogensulfate or a mixture thereof in an equivalent amount of each or in an excess of up to 10% into its lithium salt.
