RESIN COMPOSITION FOR VIBRATION-DAMPING MATERIAL

Provided is a method of providing a coat which has excellent water resistance and can sufficiently maintain excellent damping properties even under high-temperature and high-humidity conditions. The present invention relates to a damping material resin composition containing a secondary alcohol ethoxylate structure-based surfactant component and a resin having a weight average molecular weight of 60000 to 350000; a damping coating material containing the damping material resin composition and a pigment; a coat obtainable from the damping coating material; and a vehicle including the coat. The present invention also relates to a method of producing a damping material resin composition, including emulsion polymerizing a monomer component in the presence of a secondary alcohol ethoxylate structure-based surfactant to prepare emulsion resin particles having a weight average molecular weight of 60000 to 350000.
