Abstract: Low molar mass polyester polyols having a weight average molar mass Mw of up to 3500 g/mol, hydroxyl numbers of from 80 to 280 mg/g and acid numbers of from 5 to 40 mg/g, comprising structural units derived from aliphatic monocyclic or polycyclic compounds containing at least two hydroxyl and/or epoxide groups and at least one heteroatom, aliphatic acyclic or cyclic polyhydroxy compounds containing three or more hydroxyl groups per molecule, linear or branched aliphatic dihydroxy compounds and aliphatic cyclic polycarboxylic acids, alone or in a mixture with low molar mass acrylate copolymers, may be processed to give coating materials which dry rapidly, and result in defect-free surfaces.

Abstract: 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 of from 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 2
