A new covering member.

摘要

A new masking member consisting essentially of a molded foamed closed cell polystyrene base having a density from about 12.5 to about 50 g/l and an adhesive layer formed on a surface of said polystyrene base by coating said surface of said base with a composition consisting essentially of an emultion-type adhesive in which a water-soluble polymer is mixed in an amount in the range from about 0.1 to about 20% by weight of the weight of said emulsion-type adhesive, is provided in the instant invention. Said masking member is used to protect a surface of an article from a surface treatment, and is attached to a part of the surface of the article by its adhesive layer. Said adhesive layer of the masking member has a suitable stickiness, an excellent weatherability, an excellent heat resistance and a large cohesive force which prevents the adhesive layer from transferring from the masking member to the part of the surface of the article.
