| abstract |
The present invention relates to a polymeric dispersant containing an tertiary amide linkage between the aromatic anchoring group and a solubilizing chain, and a composition containing a particulate solid, an aqueous or polar organic medium, and a polymeric aromatic amide dispersant having at least one tertiary amide linking group connecting through a carbonyl group of the amide to an aromatic ring having two or more residual carboxylic acid groups or a sulfonic acid group and a residual carboxylic acidic group thereon. The invention further provides compositions for millbases, dispersions, coatings and inks containing said dispersant. |
