Abstract
Composition comprising a heterophasic propylene copolymer and two different slip agents, namely—a fatty acid amid derivative of formula (I) wherein R1 is a C5 to C25 alkyl residue or C5 to C25 alkenyl residue, R2 is a long-chain organic residue containing at least 6 carbon atoms, and—an unsaturated fatty acid amide.

Composition comprising:
- (a) a heterophasic propylene copolymer (HECO),
- (b) two different slip agents, namely
- (b1) a fatty acid amid derivative of formula (I);
- wherein
- R1 is a C5 to C25 alkyl residue or C5 to C25 alkenyl residue,
- R2 is a long-chain organic residue containing at least 6 carbon atoms, and
- (b2) an unsaturated fatty acid amide.
12-13. (canceled)
A heterophasic propylene copolymer (HECO) comprising amounts of a fatty acid amid derivative of formula (I) [b1] and a unsaturated fatty acid amide [b2] effective to improve scratch visibility of the heterophasic propylene copolymer (HECO),
- the improvement is determined as the scratch visibility obtained by Erichsen cross hatch test and the scratch visibility of the heterophasic propylene copolymer (HECO) comprising [b1] and [b2] is least 1.0 lower (at 15N) and/or at least 1.4 lower (at 10N) than the scratch visibility of the same heterophasic propylene copolymer (HECO) but comprising neither [b1] nor [b2].
