摘要： The invention relates to a binder for powder coating materials having an oligomeric or polymeric substructure which are curable thermally and/or by means of high-energy radiation, said binder comprising in each case terminally and/or laterally at least one vinyl ether group a) and at least one group b) which is different from the vinyl ether groups a) but is coreactive with said groups a), there being on average at least one vinyl ether group a) and one coreactive group b) per oligomer or polymer molecule. The invention also relates to powder coating materials comprising such a binder and to the use of said powder coating materials for coating surfaces, especially in the form of an automotive top coat and a coil coating material.

摘要： The invention relates to a binder, preferably for coating materials, which is curable thermally and/or by high-energy radiation and comprises a mixture of substances comprising (a) as one component, monomers or polymers which have a least one vinyl ether, vinyl ester, (meth)acrylic and/or allyl group and (b) as a further component, saturated polymers and/or unsaturated polymers different from component (a), with the proviso that at least one of components (a) and (b) has structural units of the formulae (I) and/or (II) the other component (b) has structural units of the formulae (I) and/or (II) at least when it contains saturated polymers. The invention also relates to a process for preparing the binder and to a formulation which comprises the binder of the invention. This formulation is in the form of a pigmented or unpigmented coating material or powder coating material. In addition, the invention relates to a procedure for preparing coatings, which following application are cured thermally and/or by irradiation with UV light or electron beams.
