Abstract
Disclosed herein is an aqueous latex composition comprising a substantially acrylic core-shell latex, wherein a water-retaining monomer is copolymerized to the shell. The Tg of the core ranges from about 0° C. to about 12° C., and the Tg of the shell ranges from about 13° C. to about 40° C. The mean volume average particle size of the latex ranges from about 125 nm to about 200 nm. The core-shell latex comprises at least one acrylic monomer having a solubility that ranges about 10 g/L to about 30 g/L at 30° C., and this at least one acrylic monomer is present in the shell polymer in an amount greater than about 50 wt. % of all monomers in the shell. Preferably, the at least one acrylic monomer is methyl methacrylate.
