Aqueous vinyl ester/ethylene copolymer emulsions possessing good dry pick and wet pick strengths in paper coating compositions comprise a vinyl ester/ethylene copolymer colloidally dispersed in an aqueous medium, the copolymer consisting essentially of (a) a vinyl ester of a C 1 -C 12 alkanoic acid, (b) about 0.5 to 15 wt% ethylene, (c) about 0.1 to 10 wt% of an ethylenically unsaturated mono- or dicarboxylic acid or half ester thereof, (d) about 0.05 to 10 wt% of a dicyclopentadienyl acrylate, and (e) 0-50 wt% of an alkyl acrylate. |
