<p>The present invention provides: a core-shell latex composition comprising latex particles, each latex particle comprising: (a) a core comprising a (co)polymer comprising (meth)acrylate ester; (b) a shell, surrounding the core, comprising a copolymer, wherein the copolymer comprises: i) a nitrogen-bearing ethynelically-unsaturated free-radically polymerizable monomer; ii) at least one (meth)acrylate ester of about a C1 to about a C14 alcohol; and iii) an optional ethylenically-unsaturated free-radically polymerizable silane monomer; wherein the nitrogen-bearing ethylenically-unsaturated free-radically polymerizable monomer comprises from about 15 to about 60 percent by weight of the shell and further wherein the core comprises from about 40 to about 85 percent of the weight of the total core-shell latex particle. The invention also relates to the use of the core-shell latex composition as a binder or primer for coatings and adhesives.</p> |
