Abstract
The present invention concerns weakly anionic polymers including their use in paper coatings, especially those intended for paper for inkjet printing. These additives provide the sought thickening function, while improving water retention very appreciably. The invention also concerns a method of manufacture of such coatings, together with the coatings obtained in this manner.
