Abstract
Polyamine additives are disclosed that are useful to provide early water resistant to drying anionically colloidally stabilized polymer dispersions in aqueous media. The polyamines are polymerization products from ethylenically unsaturated monomers with pendant tertiary amine groups with ethylenically unsaturated monomers with pendant poly(alkylene oxide) chains of 88 to 1200 g/mole molecular weight.
