  • Water-soluble dyestuffs readily convertible into insoluble form and process for preparing them
    Patent number: 3972904
    Abstract: Water-soluble dyestuffs of the general formula ##EQU1## WHEREIN F represents the radical of a water-insoluble anthraquinone dyestuff, X represents an oxygen atom, a sulfur atom or a nitrogen atom which is substituted by a hydrogen atom, a lower alkyl, phenyl, lower acyl or sulfonyl group and Me represents an alkali metal or ammonium ion made by solubilizing insoluble dyestuffs which may be indigo, nitro, azo, imide, anthraquinone, oxazine, thiazine, dioxazine, quinoline, methine, polymethine or phthalocyanine dyestuffs. The water-soluble dyestuffs are adapted to be used in dyeing and printing synthetic fibers and are characterized by the fact that they can easily be converted during the process of dyeing to the original water-insoluble dyestuffs by the influence of heat. They are especially useful for the dyeing of polyester in which material they yield deep dyeings.
