Abstract: Thermoplastic molding materials which have high gloss and are readily colored and comprise a first graft copolymer A of an elastomeric, crosslinked acrylate polymer as the graft base and a graft shell made from a vinyl-aromatic monomer and a polar, copolymerizable, ethylenically unsaturated monomer, and a second separately prepared graft copolymer B of an elastomeric crosslinked acrylate polymer as the graft base, which is different from that in A and has a larger mean particle diameter than the graft base of copolymer A, having a first graft shell of a vinyl-aromatic monomer and a second graft shell of a mixture of a vinyl aromatic monomer and a polar-copolymerizable, ethylenically unsaturated monomer, and a hard matrix C.
