Thermoplastic moulding composition (F), comprising: A) from 5 to 80% by weight of a graft polymer (A) having bimodal particle size distribution and a moisture content of 0 to 27% by weight, made, based on (A), a) from 40 to 90% by weight of an elastomeric particulate graft base (a), obtained by emulsion polymerization of, based on (a), a) from 70 to 100% by weight of at least one conjugated diene, or of at least one C-alkyl acrylate, or of mixtures of these, a) from 0 to 30% by weight of at least one other monoethylenically unsaturated monomer and a) from 0 to 10% by weight of at least one polyfunctional, cross linking monomer; a) from 10 to 60% by weight of a graft a2), made, based on a2), a) from 64 to 76% by weight of at least one vinyl aromatic monomer, a) from 24 to 36% by weight of acrylonitrile, a) from 0 to 30% by weight of at least one other monoethylenically unsaturated monomer, and a) from 0 to 10% by weight of at least one polyfunctional, cross linking monomer; B) from 10 to 94% by weight of a thermoplastic polymer (B) having a viscosity number VN of from 50 to 120 ml/g, made, based on (B), b) from 64 to 72% by weight of at least one vinyl aromatic monomer, b) from 28 to 36% by weight of acrylonitrile, and b) from 0 to 4% by weight of at least one other monoethylenically unsaturated monomer; whereby, the difference of the acrylonitrile content in component (B) and that in the graft shell a) is minimal 2% by weight and maximal 6% by weight and optionally further components, have preferred optical appearance when coated with metal.
