Title:
COATING COMPOSITION, COATING FILM, AND COATED STEEL PLATE
Document Type and Number:
WIPO Patent Application WO/2015/012290
Kind Code:
A1
Abstract:
 This coating composition contains a coating film-forming resin, a crosslinking agent, at least one vanadium compound selected from the group consisting of alkaline earth metal salts of vanadic acid and magnesium vanadate, and magnesium triphosphate, the vanadium compound being a compound having electrical conductivity of 200 μS/cm-2,000 μS/cm at a temperature of 25°C in a 1 mass% aqueous solution. The vanadium compound content, expressed with respect to a total of 100 mass parts of the solids fraction of the coating film-forming resin and the solids fraction of the crosslinking agent, is more than 50 mass parts, but no more than 150 mass parts. The vanadium compound has pH of 6.5-11 in a 1 mass% aqueous solution thereof, and the content of the magnesium triphosphate, expressed with respect to a total of 100 mass parts of the solids fraction of the coating film-forming resin and the solids fraction of the crosslinking agent, is 1-150 mass parts.
