<p>A masking material (11) which is rich in heat resistance and is repeatedly usable. The masking material (11) is made of a polymer alloy having a sea-island structure comprising a polyolefin as the continuous phase and one or more engineering plastics selected from the group consisting of a methylpentene copolymer, polysulfone, polyether sulfone, polyphenylene sulfide, polyphenylene ether, polyamideimide, polyetherimide, and polyetheretherketone as the dispersed phase.</p> |
