PROBLEM TO BE SOLVED: To provide a vibration-proof coating composition capable of enhancing vibration-proof property by containing a large amount of mica and enhancing drying property of the vibration-proof coating composition. SOLUTION: In the vibration-proof coating composition, a water-based resin dispersion in which a resin particle forming a coating film is dispersed in a water-based dispersion medium and mica for enhancing vibration-proof property of the coating film are contained. The content of mica is 150 pts.mass or more relative to 100 pts.mass of the resin particle contained in the composition and is 150 pts.mass or more relative to 100 pts.mass of a moisture content contained in the composition. In the vibration-proof coating composition, a copper powder and calcium carbonate are further contained. A mass ratio (a/b) of the mass (a) of the copper powder to the mass (b) of calcium carbonate is in a range of 1/4-2/5. COPYRIGHT: (C)2010,JPO&INPIT
