摘要:
The present invention relates to an aqueous coating material containing polymer (I), colloidal silica (II), and nonionic surfactant (III) with an HLB value of 16 or more. The polymer (I) is obtained by copolymerization of monomer mixture (M) that contains 0.2 to 10% by mass of monomer (a) having two or more radically polymerizable groups. The solid content of the colloidal silica (II) is 0.1 to 20 parts by mass with respect to 100 parts by mass of the polymer (I). The content of the nonionic surfactant (III) is 0.01 to 10 parts by mass with respect to 100 parts by mass of the polymer (I). The present invention also relates to a painted article where the aqueous coating material is applied. Therefore, an aqueous coating material and a painted article capable of expressing stain resistance and weather resistance can be provided by reducing a water contact angle.
