Abstract:
1. An aqueous dispersion comprising: (a) at least one ethyl acrylate/acrylonitrile copolymer comprising structural units derived from ethyl acrylate and acrylonitrile; (b) at least one vinyl acetate polymer selected from vinyl acetate homopolymer and vinyl acetate copolymers comprising in polymerized form vinyl acetate and ethylene; (c) water; and (d) optionally up to 50% by weight of an inorganic filler, based on the total weight of the aqueous dispersion, (e) hydroxyethyl cellulose, (f) aluminum silicate, and (g) sodium oleate, wherein the weight ratio of ethyl acrylate/acrylonitrile copolymer(s) (a) to vinyl acetate polymer(s) (b) is from 30:70 to 70:30, selected such that the aqueous dispersion, when dried, has from 17% to 270% elongation at break, and from 0.226 to 0.546 N/mm bond strength to paper.
