Coating compositions and methods for their preparation are described. The coating compositions can include a first copolymer produced by emulsion polymerization and derived from one or more monomers including one or more (meth)acrylates, one or more acid monomers, and optionally styrene. The first copolymer can have a Tg from &#x2212;50&#xb0; C. to &#x2212;23&#xb0; C. and is present in an amount of 10-50% by weight based on the total polymer content. The coating compositions can also include a second copolymer produced by emulsion polymerization and derived from one or more monomers including one or more (meth)acrylates, one or more acid monomers, and optionally styrene. The second copolymer can have a Tg from &#x2212;15&#xb0; C. to 25&#xb0; C. and is present in an amount of 50-90% by weight based on the total polymer content. Further described herein are dried coatings, methods for coating a substrate, and methods for producing a coating.
