Molded articles of thermoplastic elastomer obtained in accordance with the present invention comprise a molded product prepared from a thermoplastic elastomer containing a partially cross-linked product of ethylene/α-olefin copolymer rubber and a polyolefin resin, a primer layer containing at least one compound selected from the group of saturated polyesters and chlorinated polyolefins and formed on the surface of said molded article, and a topcoat layer containing at least one compound selected from the group of saturated polyesters, acrylic ester resins, polyvinyl chloride and polyisocyanate (provided that the topcoat layer contains at least the acrylic ester resin when the primer layer consists only of the saturated polyester) and formed on said primer layer. The molded articles of the invention mentioned above have such excellent surface characteristics that the surface thereof is hard to get a scratch, excellent in appearance as well as in touch and, moreover, is hard to subject to attack by hydrocarbon solvents.
根据本发明获得的热塑性弹性体模塑制品包括:由热塑性弹性体制备的模塑制品,该热塑性弹性体含有乙烯/α-烯烃共聚橡胶和聚烯烃树脂的部分交联产物;在所述模塑制品表面形成的底漆层,该底漆层含有至少一种选自饱和聚酯和氯化聚烯烃组的化合物;以及含有至少一种选自饱和聚酯、丙烯酸酯树脂、聚氯乙烯和聚异氰酸酯组的化合物的面漆层(条件是面漆层含有乙烯/α-烯烃共聚橡胶和聚烯烃树脂的部分交联产物)、以及在所述底漆层上形成的面漆层,该面漆层含有至少一种选自饱和聚酯、丙烯酸酯树脂、聚氯乙烯和聚异氰酸酯组的化合物(前提是当底漆层仅由饱和聚酯组成时,面漆层至少含有丙烯酸酯树脂)。上述本发明的模塑制品具有极佳的表面特性,其表面不易出现划痕,外观和触感极佳,而且不易受到烃类溶剂的侵蚀。
