Abstract

The present invention relates to composition and an article prepared by applying the composition to paper. The composition comprises an aqueous dispersion of acrylic or styrene acrylic polymer particles having a hard phase and a soft phase, wherein both phases comprise structural units of an specific acid monomer. The composition further includes sub-stoichiometric levels of a Znor Zrwith respect to the carboxylic acid groups. The composition is useful as imparting block and tack resistance as a coating on paper.
