Abstract: A masterbatch composition is provided which provides a polypropylene resin composition having good surface appearance and excellent fluidity. A masterbatch composition containing: 65 to 85 wt% of a propylene (co) polymer as component (1) containing 0 to 3 wt% of ethylene or one or more C4-C10-α-olefin-derived units; and 15 to 35 wt% of a propylene-ethylene copolymer as component (2) containing 25 to 35 wt% of ethylene-derived units, wherein the masterbatch composition satisfies the following requirements: 1) the composition has a melt flow rate (230°C, load: 21.18 N) of 5 to 30 g/10 minutes; 2) xylene insolubles of the composition have an Mw of 10 x 10 4 to 30 x 10 4 and an Mw/Mn of 6 to 20 as measured by GPC; and 3) xylene solubles of the composition have an intrinsic viscosity of 5.5 to 9.0 dl/g.
