PROBLEM TO BE SOLVED: To have excellent photographic properties, dimension precision, physical strength, injection moldability, mar resistance and the like, and also good sliding properties and to prevent light fogging by reflected light in injection molded articles for photographic sensitized materials such as photographic film spools. SOLUTION: Injection molded articles have a melt flow rate (under the condition of ASTM D 1238G) of 2-40 g/10 min, a flexural modulus (JIS K 7203) of at least 18,000 kg/cm2, and a molecular distribution of at most 5, and contain 100 pts.wt. rubbery polymer-containing aromatic monovinyl resin containing 1-40 wt.% rubbery polymer and 0.1-10 pts.wt. silicone resin and are allowed to have a surface reflective glossiness of at most 45%.
