An aqueous coating composition comprising fine polymer particles dispersed in an aqueous medium and an inorganic filler, wherein said fine polymer particles comprise synthetic rubber emulsion polymer particles having a glass transition temperature of 0 DEG C. or less and emulsion polymer particles having a glass transition temperature of 20 DEG C. or more, and further, according to circumstances, urethane emulsion polymer particles. This composition has various properties as a chipping-resistant coating agent in good balance and is particularly useful for coating of the outdoor sheet metal working members of wheeled vehicles. |
