Provided is an aqueous composition comprising latex polymer particles that comprise (a) 40% to 95%, by weight based on the dry weight of the latex polymer, a core polymer that comprises (i) polymerized units of one or more monofunctional vinyl monomers, and (ii) polymerized units of one or more multivinyl monomers, and (b) 5% to 60%, by weight based on the dry weight of the latex polymer, a shell polymer that comprises (i) polymerized units of one or more monofunctional vinyl monomers, and (ii) polymerized units of one or more vinyl monomers having a latent crosslinking group selected from the group consisting of trialkoxysilyl groups, oxoacetyl groups, and mixtures thereof.
