Claim:
1. A thermoplastic composition comprising the following components: a) 30 to 90 wt % of one or more styrene copolymers composed of styrene and/or α-methylstyrene and of acrylonitrile and optionally further monomers, as component A; b) 10 to 70 wt % of a plurality of impact-modifying graft rubbers without olefinic double bonding in the rubber phase, as component B, wherein said component B comprises: c) 0 to 20 wt % of one or more added substances distinct from component A, graft rubber component B1, and graft rubber component B2, as component C; with the proviso that the weight percent values are in each case based on the total weight of the components A, B, and C and said components altogether sum to 100 wt %, wherein the graft rubber component B2 employed is an acrylate-styrene-acrylonitrile (ASA) graft copolymer comprising as the polymeric substrate an acrylic ester polymer B21 and which comprises at least three different polymeric superstrates B22, B23, and B24,
