Abstract
Aqueous vinyl ester copolymer emulsions possessing good dry pick and wet pick strengths in paper coating compositions comprise a vinyl ester copolymer colloidally dispersed in an aqueous medium, the copolymer consisting essentially of (a) a vinyl ester of a C.sub.1 -C.sub.12 alkanoic acid, (b) about 0.1 to 10 wt % of an ethylenically unsaturated mono- or dicarboxylic acid or half ester thereof, (c) about 0.05 to 10 wt % of a dicyclopentadienyl acrylate, and (d) 0-50 wt % of an alkyl acrylate.
