Abstract
An aqueous composition including multi-stage latex polymer particles is provided. The multi-stage latex polymer particles include (A) a first-stage polymer containing (i) an ethylenically unsaturated acid monomer with two carboxylic acid groups and (ii) a first vinyl monomer, and (B) a second-stage polymer containing (i) an ethylenically unsaturated monomer with an epoxy group and (ii) a second vinyl monomer. An article including a nonwoven textile impregnated with the aqueous composition is also provided.
