Abstract
Provided is a process for producing a coating on a substrate comprising one or more steps of crushing a dried layer of a foamed aqueous coating composition, wherein the aqueous coating composition comprises a collection of multi-stage copolymer particles having a weight average diameter of 2-20 μm, wherein said multi-stage copolymer particles comprise a core having a glass transition temperature (Tg) of 20° C. or less. Also provided is a coated substrate made by that process.
