The present invention relates to a dispersant derived from anhydride functionalized polyester derived from carboxylic acid functionalized polyester. The anhydride functionalized polyester is then reacted with a multi-amine species forming amide and salt bonds. The technology allows lower reaction temperatures when the multi-amine species is present. The lower reaction temperature allows the use of a broader selection of polyester repeat units.
