Abstract
Resin coated papers having improved properties especially edge penetration are made using an alkyl ketene dimer neutral size, a wet strength resin and an anionic polyelectrolyte to control the streaming potential of the papermaking stock during manufacture of the paper. Advantageously a supplementary size especially an epoxidized fatty acid amide is also used.
