AQUEOUS RESIN DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide an aqueous resin dispersion which enables formtaion of a coated film excellent in weatherability and blocking resistance. SOLUTION: The aqueous resin dispersion is obtained by polymerizing two or more types of polymerizable monomers having different glass transition temperatures (Tg) and is composed of a high Tg component having a glass transition temperature (Tg) of not lower than 50°C and a low Tg component having a glass transition temperature (Tg) of not higher than 40°C and has a ratio (weight ratio) of the high Tg component to the low Tg component of 46/54 to 70/30.
