PROBLEM TO BE SOLVED: To provide a visually transparent injection-molded article with improved toughness and stress cracking resistance obtained from a molding composition with improved moldability.SOLUTION: The invention relates to a molded article, wherein an acid component comprises 70-100 mol% of repeat units which are 90-40 mol% of terephthalic acid and 10-60 mol% of one or more additional dibasic acids selected from the group consisting of isophthalic acid and naphthalene dicarboxylic acid; and a glycol component comprises repeat units from 1,4-cyclohexane dimethanol. The molded article is prepared from a copolyester having an inherent viscosity of 0.4-1.1 dL/g obtained in a 60/40 phenol/tetrachlorethane solution containing 0.5 g of polymer in 100 mL of solution, and the molded article has diffusion transmittance value of <60% as determined by ASTM Method D1003. |
