Abstract
To provide an aqueous coating composition with which a coating film having a sufficient self-cleaning function can be formed even in a case where an aqueous fluorinated resin dispersion is blended as an aqueous synthetic resin dispersion or a case where an isocyanate compound is contained as a curing agent can be formed; an aqueous coating material kit with which the aqueous coating composition can be obtained; and an article having a coated film having a sufficient self-cleaning function.An aqueous coating composition, which comprises an aqueous synthetic resin dispersion and a urethane polyol, wherein the urethane polyol is a reaction product of a polyoxyalkylene diol having as units an oxyalkylene group of a structure such that an oxygen atom is bonded to one end of a branched alkylene group, and an aliphatic diisocyanate.
