ABSTRACT:
Dispersants, especially well suited for use with insoluble dyes, are produced by reacting hydroxyl benzyl alcohol compounds with sulfonated lignin derivatives. The dispersants have high levels of heat stability, coupled with desirable dye reduction, staining, foaming, milling and viscosity-reducing properties. Dyestuffs, dye pastes and dye baths, as well as methods utilizing them, are provided.
