Abstract
The present disclosure provides an aqueous composition. The aqueous composition includes multi-stage latex polymer particles. The multi-stage latex polymer particles include (A) a first-stage polymer containing (i) an n-methylol functional monomer and (ii) a first vinyl monomer; and (B) a second-stage polymer containing (i) a formaldehyde-scavenging monomer and (ii) a second vinyl monomer. The first-stage polymer is bound to the second-stage polymer.
