Abstract

To provide a curable composition capable of providing a cured product which is excellent in physical property balance of flexibility, low-temperature characteristics, and chemical resistance and particularly has extremely good physical properties of chemical resistance, and to provide a synthetic leather.SOLUTION: The curable composition contains a component (a): a polycarbonate polyol having a hydroxyl value of 40-75 mg KOH / g, a component (b): a polycarbonate polyol having a hydroxyl value of 100-280 mg KOH / g, and a component (c): a polyisocyanate having an average number of functional groups of 2-6 per molecule. The polycarbonate polyols as the components (a) and (b) contain a repeating unit represented by formula (1), a terminal hydroxyl group, and a structure represented by formula (A). At least one of the components (a) and (b) contains a repeating unit represented by formula (1) in which R1 has three carbon atoms.SELECTED DRAWING: None
