Claim:
A reusable masking member protect a prescribed part of an article from a coating applied to said article, said masking member being a polymer alloy manufactured by molding a sheet comprising one or more kinds of engineering plastics ( 1 ), polyamide and/or polystyrene ( 2 ), and styrenic thermoplastic elastomer ( 3 ), wherein said engineering plastics ( 1 ) are selected from the group consisting of methylpentene copolymer, polysulphone, polyethersulphone, polyphenylene sulphide, polyphenylene ether, polyamideimide, polyetherimide, and polyether-etherketone; and said engineering plastics ( 1 ) and said polyamide and/or polystyrene ( 2 ) are mixed together in a weight ratio of 30:70 to 70:30, and then 2 to 20 parts by weight of said styrenic thermoplastic elastomer ( 3 ) is added in 100 parts by weight of a combination of said engineering plastics and polyamide and/or polystyrene, said masking member having an affinity with said coating so as to avoid pieces of said coating peeling off from said masking member and contaminating the area adjacent to said prescribed part.
