<p>PURPOSE:To form a vessel which has luster with arbitrary distorted patterns, by using a specified resin compound and controlling the orientation of dispersed particles having a specified nearly bar-shaped form. CONSTITUTION:A resin compound which consists of thermoplastic polyester resin (A) of 98-50 pts.wt. and thermoplastic resin (B) of 2-50 pts.wt. incompatible with resin (A) and has a larger difference in refractive index than 0.05 between the resins (A), (B) in the non-orientation state at 25 deg.C, is molded by injection or extrusion to obtain preliminary moldings in which bar-shaped resin (b) are arranged in the flowing direction of the resin compound. Next, when the preliminary molding is processed with blow molding, temperature distribution is give at an arbitrary position or other ways are applied to change the oriented direction of the resin (b), which is a bar-shaped dispersion phase in the matrix resin (a), to optional directions. In this way, an optional pattern can be displayed without making the face of a molding uneven.</p> |
