3〜5000であることが望ましい。When the aqueous coating composition of the present invention is applied to the surface of an object to be coated to form a coating film, the surface to be coated is covered with the filler (B) in the form of fibers or needles filled in the coating film. In this protected state, the filler (B) protects the surface of the underfloor member from pebbles, sand, etc. blown away during driving, and protects the coated surface from scratches. However, if the filler (B) has a diameter of 0.3 microns or less, the mechanical strength of the filler (B) is weak, and there is a risk that the filler (B) will be damaged by collisions with pebbles, sand, etc., resulting in a decrease in coverage. If the diameter is 100 microns or more, the filler (B) filled in the formed coating film will not be dense, and gaps will be created between the fillers (8), resulting in poor coverage. Furthermore, if the length of the filler (B) is 50 microns or less, the fillers (B) do not intertwine with each other, resulting in poor coverage, and if the length of the filler (B) is 2000 microns or more, the filler ( B) The degree of mutual entanglement becomes excessive, causing problems in paint stability and painting workability. In order to maintain good coating stability and coating workability and obtain good coverage, it is desirable that the aspect ratio of the filler (B) is 3 to 5000.

Furthermore, in order to improve the weather resistance of the vinylidene chloride and/or vinyl chloride, it is desirable to copolymerize an alkyl acrylate and/or alkyl methacrylate (C) containing 1 to 12 carbon atoms in the alkyl group. For the water permeability and moisture resistance of the membrane, the alkyl acrylate and/or alkyl methacrylate (c) should be added in an amount of 45 parts by weight when the total of vinylidene chloride (a) and vinyl chloride (b) is 100 parts by weight. It is desirable that the content is less than part by weight. Furthermore, it is desirable to copolymerize α-β unsaturated carboxylic acid (d) in order to improve the adhesion to metal surfaces, especially non-ferrous metal surfaces such as zinc, but the amount of α-β unsaturated carboxylic acid is If it exceeds 30% by weight, the water resistance of the coating film will be poor.
