Abstract: Binders for coating materials that exhibit high flexibility and good hardness contain a polymer-modified resin, containing I) at least one polyester having a hydroxyl group or a carboxyl group or both, and II) at least one glycidyl-containing polyacrylate. The polyester I contains an alcohol component containing of from 0.5 to 80 mol % of a dicidol fraction, and the resin is obtained by free-radical polymerization of the starting component(s) for the preparation of the polyacrylate II in the presence of the polyester I in at least one organic solvent.

Abstract: An aqueous dispersion, contains: a) an amorphous urethanized, unsaturated polyester resin, b) a nonvolatile content of from 20% to 60% by weight, c) from 0 to 60% by weight of a solvent, d) a pH of between 5.0 and 9.5, and e) a viscosity at 20° C. of from 20 to 500 mPas. The polyester resin is obtained from I. an alcohol component, II. i) from 20 to 100 mol % of an ?,?-unsaturated carboxylic acid component, and ii) from 0 to 80 mol % of a further carboxylic acid component, and III. at least one isocyanate component. The alcohol component contains a dicidol mixture of the isomeric compounds 3,8-bis(hydroxymethyl)tricyclo[5.2.1.02,6]decane, 4,8-bis(hydroxymethyl)tricyclo[5.2.1.02,6]decane and 5,8-bis(hydroxymethyl)tricyclo[5.2.1.02,6]decane. Each isomer is present in a fraction of from 20 to 40% in the dicidol mixture. The sum of the three isomers in the dicidol mixture is from 90 to 100%. The dicidol mixture is present from 10 to 100 mol % in the alcohol component of the polyester.
