<p>A paper composition and method of making affording enhanced rosin sizing of paper containing metal salts are disclosed. The paper composition comprises a rosin type paper composition and filler or coating material and rosin in increased amounts. The method of making comprises use of a scavenger to reduce the amount of free divalent cations which can inhibit the rosin sizing of the paper composition. The scavenger can be a chelating or precipitating type agent having a phosphate moiety. The invention affords reduction or prevention of soap formation in rosin sizing systems, particularly those for papers having calcium carbonate fillers.</p> |
