<p><P>PROBLEM TO BE SOLVED: To provide a masking material with an excellent heat resistance and a sufficient dimension stability. <P>SOLUTION: The masking material uses a thermoplastic synthetic resin as a material and is molded to a predetermined shape. In the masking material, a degree of crystallinity of the thermoplastic synthetic resin of the masking material is 20% or higher. The thermoplastic synthetic resin having the degree of crystallinity of 20% or higher provides the masking material with the excellent heat resistance and the sufficient dimension stability. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
