Abstract
Provided is a polyurethane urea resin composition exhibiting UV absorption-agent resistance that achieves both durability and liquid resistance against UV absorption agents included in cosmetic products or the like, and that is capable of being used for a moulded body and a coating material which exhibit excellent properties such as abrasion resistance, mar resistance, oleic acid resistance, water resistance, stain resistance, and weather resistance. The polyurethane urea resin composition exhibiting UV-absorption-agent resistance is obtained by reacting a polyol (A), a polyisocyanate (B), a molecular weight modifier (C), and a diamine (D), and can be used as a moulded body and a member-coating material to impart durability and liquid resistance against UV absorption agents,
