PURPOSE:To provide a lowly bleeding injection molded article excellent in transparency, ridigity, etc., by adding a specified amount of a specified metal aromatic phosphate and injection-molding this mixture. CONSTITUTION:0.01-1pts.wt. metal aromatic phosphate (B) of the formula (wherein R1 and R2 are each H or an alkyl, M is a Group Ia or IIa metal, X is an alkylidene, and a is the valence of M) is added to 100pts.wt. crystalline propylene random copolymer (A) of a metal flow rate of 10-80g/10min and an ethylene content of 0.5-7wt.%. The obtained composition is injection-molded to produce a lowly bleeding injection molded article. The obtained article can be suitably used as a food container, a medical appliance or the like. Examples of component B include sodium 2,2'-methylenebis(4,6-di-t-butylphenyl)phosphate.
