An object of the present invention is to provide, for example, a polyol composition that can be used as a starting material in producing synthetic leather without a solvent, and a method for producing synthetic leather without a solvent. Another object of the present invention is to provide, for example, a polyol composition that produces a polyurethane film excellent in flexibility, chemical resistance, and moist heat resistance and serves as a starting material in producing synthetic leather without a solvent. The present invention provides a polyol composition for a starting material for synthetic leather production without a solvent, the polyol composition having a carbonate skeleton, having a viscosity of 100 to 1250 mPa·s measured at 50°C by a method of JIS K 1557-5 (2007), and having a hydroxyl value of 40 to 75 mgKOH/g measured by a method of JIS K 1557-1 (2007). |
