    摘要： The invention relates to solvent-based coating compositions, comprising at least one hydroxy-functional (meth)acrylic copolymer I having an OH-value from 40 to 260 mg KOH/g, and a number average molecular mass (Mn) from 1,300 to 20,000 g/mol, which comprise the following polymerized components:

    A. 15 to 70 wt-%, preferably 20 to 40 wt-% of at least one polyalkyleneglycol (meth)acrylate,
    B. 0 to 70 wt-%, preferably 10 to 50 wt-% of at least one vinylaromatic olefinically unsaturated monomer capable of radical polymerization,
    C. 10 to 60 wt-%, preferably 15-40 wt-% of at least one hydroxy-functional olefinically unsaturated monomer capable of radical polymerization that is different from A,
    D. 0 to 60 wt-%, preferably 5-50 wt-% of at least one olefinically unsaturated monomer capable of radical polymerization that does not contain further functional groups and
    E. 0 to 40 wt-%, preferably 0-30 wt-% of at least one olefinically unsaturated monomer capable of radical polymerization that is different from A, B, C and D,
    whereby the sum of the proportions of components A to E totals 100 wt-%.

    摘要： The invention relates to hydroxy-functional (meth)acrylic copolymers having an OH value from 40 to 260 mg KOH/g, a number average molecular mass (Mn) from 1500 to 20000 g/mole and a glass transition temperature Tg from -40 °C to 80 °C, containing

    A) polymerized monomers of at least one epoxy-functional, olefinically unsaturated monomer,
    B) at least one compound having a carboxyl group and at least one hydroxyl group in the molecule that is reacted with the epoxy functional group of the polymerized olefincially unsaturated monomers,
    C) at least one additional polymerized olefinically unsaturated monomer capable of radical polymerization which is different from component A) and
    D) optionally at least one lactone reacted with the polymer.
    It also relates to processes for making the copolymers and to coating compositions that contain the hydroxy-functional (meth)acrylic copolymers and to the use thereof in multi-layer automotive coatings.
