WEAKLY IONIC POLYMERS FOR AN AQUEOUS SUSPENSION OF MINERAL FILLERS FOR PAPER COATING COLORS INTENDED FOR INK JET PRINTING

摘要

The present invention provides weakly ionic polymeric additives that, when used in aqueous suspensions of commercial mineral fillers (dispersed with an anionic polymer), enable the introduction of organic or mineral salts in significant quantities without causing a destabilization of the medium. The suspension are useful in the formulation of a paper coating color designed for an application of the ink-jet type.
