摘要 |
A polyurethane resin composition containing a polyurethane resin composed of a high molecular weight polyol having a molecular weight of not less than 500, an organic polyisocyanate and optionally a compound having at least 2 active hydrogen-containing groups is disclosed. Not less than 30% by weight of the high molecular weight polyol is a polyester polyol, and the polyester polyol contains at least one tricyclic molecular skeleton in the molecular chain thereof in an amount of not less than 20 mole % based on total acid or glycol components.
