Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a synthetic leather having the same physical properties and durability as those of conventional petroleum-derived resins by solving problems of durability of conventional plant-originated component resins having biodegradability such as polylactic acid resin. SOLUTION: In the synthetic leather, a polyurethane resin membrane containing 30-65 wt.% plant-originated component is formed on one side face of a fabric by a coating method or a conjugation method. A castor oil diol is preferably used as a polyol component constituting the polyurethane resin. COPYRIGHT: (C)2009,JPO&INPIT
