Abstract
A “one-shot” composition for use in paper sizing comprises an admixture of a rosin emulsion, a soluble aluminium salt and a cationic starch derivative which has a charged state of 1.0 to 3.5 m equivalents per gramme and which is produced by a process in which the starch structure was split prior to the cationising step.
