The invention relates to a molding composition (P) comprising: (A) 83.2 to 98.5 wt.-% of a thermoplastic polymer composition (A) comprising: (A-1) at least one graft copolymer (A-1), and (A-2) at least one thermoplastic matrix polymer (A-2) based on one or more vinylaromatic copolymers; (B) 1.5 to 3 wt.-% of carbon black (B) or a mixture of carbon blacks (B); (C) a hindered amine light stabilizer composition (C), comprising at least two of substances (C-1) to (C-3): (C-1) 0 to 0.9 wt.-%, based on the total weight of the molding composition (P), of at least one hindered amine light stabilizer having a dipiperidine structure with at least one alkyl group at each of the 2 and 6 positions of the dipiperidine structure, (C-2) 0 to 0.9 wt.-% of a hindered amine light stabilizer mixture having a monopiperidine structure with at least one alkyl group at each of the 2 and 6 positions of the monopiperidine structure and (C-3) 0 to 2 wt.-%, of at least one hindered amine light stabilizer having a polymeric structure comprising piperidine groups with at least one alkyl group at each of the 2 and 6 positions of the piperidine groups provided that the at least one hindered amine light stabilizer composition (C) is present in the molding composition (P) in an amount of at least 0.2 wt.-%; (D) 0 to 5 wt.-%, of one or more further additives (D), different from (B) and (C); and (E) 0 to 5 wt.-%, of one or more further colorants, dyes or pigments (E), different from (B) and (D); wherein the constituents (A) to (E) sum up to 100 wt.-% of the molding composition (P).
