    Abstract: Aqueous matte coating compositions and methods for applying aqueous matte coating compositions to substrates are disclosed. The compositions comprise (a) from 10 to 65 wt % of a first acrylic bead having a calculated glass transition temperature (“Tg”) of from −30 to 10° C. and an average diameter particle of from 0.1 to 2 μm, (b) from 20 to 80 wt % of a second acrylic bead having a calculated Tg of from −60 to 0° C. and an average particle diameter of from 0.5 to 30 μm, optionally (c) from 10 to 30 wt % of a polymer binder having an average particle diameter of 0.03 to 0.5 μm, and (d) a slip additive. In some embodiments, the slip additive comprises a silicone emulsion and a wax dispersion. In some embodiments, the slip additive comprises a polyurethane dispersion. Methods for applying aqueous matte coating compositions are also disclosed.
