Zusammenfassung:	PURPOSE:To provide a pigmented propyelene polymer compsn. having excellent transparency and weather resistance, by blending a specified di-substd. benzylidenesorbitol and a hindered amine in combination as nucleating agents with a propylene polymer and further blending a pigment therewith. CONSTITUTION:0.01-0.5pts.wt. di-substd. benzylidene-sorbitol of formula I (wherein Ro is a 1-8C alkyl, alkoxy; l is 0,1; m, n are each 0-3; m+n>=1), 0.01- 1pts.wt. hindered amine of formula II (wherein R1 is a 1-8C alkyl; R2 is H, etc.; R3 is a group attached through a carbon, oxygen or nitrogen atom to the carbon atom on the heterocyclic ring) and 0.0001-0.5pts.wt. org. or inorg. pigment such as iron oxide, are blended with 100pts.wt. propylene polymer having a melt flow rate of 0.1-100g/10min to obtain the desired propylene polymer compsn.
