PURPOSE:To provide the titled composition containing a water-soluble or water- dispersible vinyl polymer and a polyvinylidene fluoride fine powder at a specific ratio, and giving a coating film having excellent weather resistance, water resistance, corrosion resistance and various other physical properties. CONSTITUTION:The objective composition can be prepared by using (A) 30- 95pts.wt. of a water-soluble vinyl polymer and/or a water-dispersible vinyl polymer [e.g. a polymer derived from >=10wt% of a monomer such as methyl (meth)acrylate or (meth)acrylonitrile, etc.] and (B) 70-5pts.wt. of fine powder of polyvinylidene fluoride, as essential components.
