Abstract
Disclosed herein is an aqueous latex composition comprising latex particles dispersed in an aqueous solution, wherein the latex particles are polymerized from at least one acrylic monomer in a substantially solvent-free, waterborne environment, and a 2-oxazoline compound is incorporated onto the latex particles. The 2-oxazoline compound has the following structure: The 2-oxazoline compound is present from about 1 wt. % to about 5 wt. %. The 2-oxazoline may be grafted onto the latex particles. R1 moiety may be free of an acyclic organic radical having addition polymerizable unsaturation moiety. The aqueous latex composition may also comprises an acid monomer.
