The present invention relates to a polypropylene-based composition, an article comprising the polypropylene-based composition, and the use of the following copolymer (B) for reducing the paint adhesion failure rate of the article comprising the polypropylene-based composition, The propylene-based composition (A) has a xylene cold soluble (XCS) fraction content in the range of 15% to 35% by weight, based on the total weight of the heterophasic propylene copolymer, 40.0 to 85.0 weight % Heterophasic propylene copolymer; (B) 5.0 to 15.0% by weight of ethylene having a melting temperature Tm of less than 140° C., as measured in a differential scanning calorimeter (DSC) and polymerized in the presence of a single site catalyst system, and alpha- having 4 to 12 carbon atoms. Random copolymers of propylene and comonomer units selected from olefins; (C) 5.0 to 25.0% by weight of an ethylene copolymer with an alpha-olefin comonomer unit having 4 to 12 carbon atoms with a density of 850 kg/m 3 to 900 kg/m 3; And (D) 5.0 to 25.0% by weight of an inorganic filler, wherein the amounts of components (A), (B), (C) and (D) are all based on the total weight of the polypropylene-based composition, The polypropylene-based composition has a melt flow rate (MFR 2 ) in the range of 2.0 g/10 min to 20.0 g/10 min when measured at 230° C. and 2.16 kg according to ISO 1133. |
