Abstract
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 thatat 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.
