Polycarbonate compositions having improved adhesion to polyurethane layers

A composite component comprising:

• a) a carrier composed of a thermoplastic composition comprising:
• A) 55 to 75 parts by weight of at least one polymer selected from the group consisting of aromatic polycarbonate and aromatic polyester carbonate;
• B) 25 to 45 parts by weight of at least one mixture comprising at least one polybutadiene-based graft polymer prepared by emulsion, suspension or solution polymerization and at least one polybutadiene-free vinyl (co)polymer;
• and
• C) 0.1 to 20.0 parts by weight (based in each case on the sum total of components A and B) of at least one polymer additive, where the polybutadiene content based on the sum total of the parts by weight of components A and B is 10% to 20% by weight;
• wherein the total content of butadiene-free vinyl (co)polymer from component B based on the sum total of the parts by weight of components A and B is 12% to 23% by weight, and where the sum total of the parts by weight of components A and B in the polycarbonate composition is normalized to 100;
• and
• b) at least one polyurethane layer selected from the group consisting of coating materials, foams and compact skins, comprising:
• at least one polyisocyanate component;
• least one polyfunctional H-active compound;
• and
• optionally at least one polyurethane additive and/or processing aid;
• having a molar ratio of NCO- to H-active groups of 1:1 to 1.1:1.
