(57) [Summary] [Structure] An aqueous coating composition comprising polymer fine particles dispersed in an aqueous medium and an inorganic filler, The polymer fine particles are synthetic rubber-based emulsion polymer particles having a glass transition temperature of 0 ° C. or less and a glass transition temperature of 20. C. or more emulsion polymer particles as an essential component, optionally further comprising urethane resin emulsion particles, further comprising heat-expandable polymer beads and / or hollow beads (C) for aqueous coating composition . [Effect] It has a good balance of various properties as a coating agent for chipping resistance, and is particularly useful as a coating for outdoor sheet metal working members of vehicles. |
