　The present invention provides synthetic leather suitably usable for a vehicle interior finishing material, said leather containing a plant-derived component having excellent low temperature elasticity and texture. The synthetic leather comprises a fibrous base material and a polyurethane resin formed by a reaction between a urethane curing agent and a urethane polyol prepolymer obtained using a caster oil polyol. Said leather is provided with an epidermal layer formed on one surface of the fibrous base material and a protective layer comprising the polyurethane resin and formed on top of the epidermal layer. The average number of hydroxyl groups in the coaster oil polyol used for the urethane polyol prepolymer is in the range 2.2 to 5.5. |
