    • The present invention is directed to an aqueous architectural composition comprising a low Tg (less than about -10 °C and higher than about -50°C) acrylic emulsion polymer with at least one cross-linkable moiety, and solid polyutherane (PU) or polybutylacrylate microspheres having a mean weight diameter of less than about 40 microns and a Tg of less than about 0°C, wherein the solid PU spheres make up about 10% to about 20% by weight of the composition. The solid acrylic polymer without water and the PU spheres make up about 30% to about 40% by weight of the aqueous composition. A dried paint film formed by the inventive aqueous architectural composition can withstand at least about 500 cycles on the scrub test, and a gloss value at 60° of less than about 2.5 GU.
