A new class of highly effective polymeric dispersants for inkjet applications have been developed by covalent attachment of organic chromophore groups, capable of interacting with pigments, to hydrophilic polymers. The anchoring effect of such groups is defined by molecular similarity to the pigment structure and by less specific interactions. The affinity of the chromophore to the colorant surface is amplified by connecting multiple groups to one polymer molecule. Dispersants based on styrene-acrylic or styrene-maleic anhydride polymers with attached azo dyes proved to be very effective for yellow azo pigments, such as PY74, providing inkjet compositions with very high resistance to ink formulations with multiple co-solvents and reduced particle settling. On the other hand, a quinacridone chromophore, being linked to certain hydrophilic polymers, produces a very versatile dispersant, suitable for quinacridones, phthalocyanines and Carbon Black. Synthetic pathways to new dispersants as well as properties of obtained inkjet materials are discussed.
