  • Aqueous dispersions of acrylate modified alkyd resins and use thereof
    Patent number: 6627700
    Abstract: 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.
