Beschreibung
Zusammenfassung:	Provided by the present invention is a mold release sheet used in producing resin films such as synthetic leathers and the like in which a curling phenomenon is relieved even when the sheet is formed by a thick release layer and which has a good workability in repeated use. In the mold release sheet of the present invention in which a release layer is formed on one surface of a substrate, the above release layer assumes a multilayer structure which comprises an intermediate layer formed on a substrate side by using a material I for forming coating film containing an amorphous polyolefin resin(A) alone or a resin mixture (B) composed of an amorphous polyolefin resin and a crystalline polyolefin resin and which comprises a surface layer formed on the intermediate layer by using a material II for forming a coating film containing a crystalline polyolefin resin.
