Beschreibung
Zusammenfassung:	A thermoplastic polyurethane resin according to the present invention contains a reaction product of a polyisocyanate component and a polyol component. The polyisocyanate component contains 1,4-bis(isocyanatomethyl)cyclohexane and 1,3-bis(isocyanatomethyl)cyclohexane. The polyol component contains a polycarbonate polyol and a low-molecular-weight polyol. The polycarbonate polyol contains a crystalline polycarbonate polyol that is in a solid state at 25 DEG C. Relative to the total amount of 1,4-bis(isocyanatomethyl)cyclohexane and 1,3-bis(isocyanatomethyl)cyclohexane, the amount of 1,4-bis(isocyanatomethyl)cyclohexane is 50-90% by mole and the amount of 1,3-bis(isocyanatomethyl)cyclohexane is 10-50% by mole.
