<p>Stabilized dispersions of alkyl ketene dimer paper sizing agents that comprise up to about 30% by weight of ketene dimer, a water soluble cationic starch, and a lignin sulfonate, and also contain about 0.15 to about 1.5% of aluminum sulfate and from about 0.1 to about 5% of a carboxylic acid having from 1 to 10 carbon atoms, a pKa of up to about 5 and a solubility of at least about 0.1 parts in 100 parts of water (the percentages being based upon the weight of the dimer), are disclosed.</p> |
