Abstract

The present invention relates to a composition containing a particulate solid, a polar or non-polar organic medium, and a polymer chain having at least one non-fused aromatic imide pendant group. The invention further provides compositions for coatings, inks, toners, plastic materials (such as thermoplastics), plasticisers, plastisols, crude grinding and flush.
