Thermoplastic resin molded article

TLDR: In this article, a specific composition was applied to the surface of a molded article consisting essentially of a monomer composed of a norbornene derivative having a specific structure, and the aim was to obtain the titled molded article remarkably excellent in adhesion of coating film while retaining transparency of these components useful for car, etc.

Abstract: PURPOSE: To obtain the titled molded article remarkably excellent in adhesion of coating film while retaining transparency of these components useful for car, etc., by applying a specific composition onto the surface of molded article consisting essentially of a monomer composed of a norbornene derivative having a specific structure. CONSTITUTION: The aimed composition obtained by applying (B) a mixed composition consisting of (i) 100 pts. wt. organoalkoxysilane expressed by the formula Rsi(OR') 3 (R is 1-8C organic group; R' is 1-5C alkyl, etc.) or hydrolyzate thereof or partially condensed product thereof, (ii) colloidal silica dispersed into hydrophilic solvent, of 0-50 pts. wt. expressed in terms of solid content, (iii) 0.1-50 pts. wt. water and (iv) 100-1,000 pts.wt. solvent to the surface of (A) resin molded article consisting essentially of a hydrogenated polymer obtained by further hydrogenating a ring-opened polymer obtained by subjecting a monomer consisting of at least one norbornene derivative expressed by the formula (A and B are H or 1-10C hydrocarbon; X and Y are H, 1-10C hydrocarbon, halogen, etc.) or the monomer and copolymerizable monomer copolymerizable with the monomer to ring opening polymerization.
