    摘要: Aqueous dispersion of an acrylate-modified alkyd resin, preparable in the presence of at least one water-miscible diol by (1) dispersing in water at least one alkyd resin containing pendant and/or terminal allyloxy groups, (2) graft copolymerizing a mixture of methacrylic acid and at least one further, carboxyl-free olefinically unsaturated monomer in dispersion 1, and (3) once or n times graft copolymerising (3.1) at least one olefinically unsaturated monomer which is free from acid groups and/or (3.2) at least one mixture of at least one olefinically unsaturated monomer which contains acid groups and at least one olefinically unsaturated monomer which is free from acid groups, in dispersion 2 or 2 to n−1, with the proviso that in step (3) or (n) of the process, acid groups are incorporated in a total amount to not more than 90 mol % of the amount of acid groups incorporated in step (2) of the process.

    摘要: A process for preparing binders for one-component paint systems has the following steps: (I) preparation of a polyurethane-alkyd resin component (A) composed of a mixture (a) of (a1) an unsaturated C.sub.6 -C.sub.30 fatty acid with at least two non-conjugated double bonds, and (a2) an unsaturated C.sub.6 -C.sub.30 fatty acid with at least two conjugated double bonds as esterified side polymer chains of the polyurethane-alkyd component (A); and (b) polyurethane units with anionic groups and/or groups which can be converted into anionic groups as main polymer chains of the polyurethane-alkyd resin component (A); (II) optional neutralisation of the groups in the polyurethane-alkyd resin component (A) which can be converted into anionic groups and their transfer into the aqueous dispersion or solution; and (III) polymerising at least one ethylenically unsaturated, radically polymerisable monomer (c) which has substantially no other reactive functional groups besides the C--C-- double bond in the dispersion prepared as under step (II) in the presence of a radical builder as polymerisation initiator.
