| 摘要 |
This invention discloses an aqueous resin dispersion excellent in adhesion to a base material and stability, and capable of forming a coat which exhibits excellent vibration-damping properties over a wide temperature range, and moreover, is flexible and excellent in resistance to chipping and low temperature resistance to impact, and it is an aqueous resin dispersion comprising polymer fine particles dispersed in an aqueous medium, and contains, as the polymer fine particles, composite fine particles (A) comprising a core part and a shell part having specific glass transition temperatures (Tg), respectively, specific composite fine particles (B) wherein the Tg of its core part is different from that of the composite fine particles (A), and/or polymer fine particles (C) having a specific Tg.
