Summary:PURPOSE:To improve the antihydrolysis performance, reduce the reduction of strength, and improve polishing faculty by mixing 0.1 - 6 wt. parts epoxy compound and 10 - 200 wt. parts alumina having an average particle diameter of 10 mum or less into 100 wt. parts thermoplastic polyester resin. CONSTITUTION:0.1 - 6 wt. parts epoxy compound and 10 - 200 wt. parts alumina having an average particle diameter of 10 mum or less are mixed into 100 wt. parts thermoplastic polyester resin, and a desired projection member for humid blast is obtained. Accordingly, the projection member for humid blast possesses the superior hydrolysis faculty, and the reduction of strength due to the humid blast work is little, and further, since fine alumina is uniformly dispersed, the superior polishing faculty is obtained, and the outside appearance of the resin molded article can be favorably maintained, and the projection member suitable for fine humid blast work can be obtained.
