摘要
Dyestuff compositions are provided which incorporate, as the grinding aid and/or dispersant therefor, amine modified lignin admixed with sulfonated lignin. The disclosed dyestuff compositions exhibit improved heat stability and, as a result of the higher activity of the dispersant mixture of amine modified lignin blended with sulfonated lignin, less dispersant is present in the exhaust liquor and waste treatment demands are thereby reduced. The improved package dyeing grinding aid/dispersant of the invention is prepared by mixing an amine modified lignin with a sulfonated lignin.
