Beschreibung
Zusammenfassung:	PURPOSE:To obtain a sheet material having a structure containing a layer having high plastic deformation temperature wherein the soft component having high melting temperature is composed of a crosslinked soft polyvinyl chloride resin, and capable of giving a formed article having soft feeling and excellent dimensional stability and molding stability, in a mass, without using a particular apparatus. CONSTITUTION:A sheet material having a structure containing a layer having high plastic deformation temperature to keep the high-temperature strength in vacuum forming, wherein said layer is a soft polyvinyl chloride resin layer having high melting temperature or crosslinked structure. The sheet consists of the single layer having high plastic deformation temperature, or a laminate of a layer having high plastic deformation temperature and a soft polyvinyl chloride sheet. A thermoplastic resin layer may be applied to the front and/or back surfaces of the sheet material.
