Binders for road-marking paints, comprising a (meth)acrylate copolymer A and one or more olefinincally unsaturated monomers B which can be cured by adding free-radical initiators C, wherein the binders have mass fractions of from 20 to 80% of the (meth)acrylate copolymer A and from 80 to 20% of the olefinically unsaturated monomers B, where the (meth)acrylate copolymers A are obtainable by reacting, mass fractions of, from 10 to 50% of compounds A1 selected from the group consisting offrom 10 to 50% of compounds A1 selected from the group consisting of monoexpoxides, lactones and lactams having from 4 to 18 carbon atoms,from 1 to 25% of olefinically unsaturated monomers A2 which contain at least one acid group selected from the group consisting of carboxyl groups, sulfonic acid groups and phosphonic acid groups,from 5 to 70% of methacylates A3 of linear, branched or cyclic alchohols having from 1 to 20 carbon atoms,from 2 to 84% of acrylates A4 of linear, branched or cyclic alcohols having from 2 to 20 carbon atoms, and also if desired,up to 70% of other vinyl monomers A5by free-radical polymerization, where the compounds A1 are first charged and the monomers A2 to A5, and also a free-radical initiator A7, are added.
