Abstract
Insolubilizing agents are disclosed for pigment binders and surface sizes containing functional groups capable of reacting with carboxylic acid anhydride moieties to form chemical bonds. The insolubilizing agents are polymers or other compounds containing a plurality of carboxylic acid anhydride moieties per molecular entity. The anhydride moieties do not substantially hydrolyze or otherwise react until the paper coating is applied to the paper and dried and cured, at which time the anhydride moieties react with the functional groups of the pigment binder or surface size and render it water insoluble. A method to improve the water resistance and printability of coated paper using the insolubilizing agents of the invention is also disclosed.
