USE OF A RADIO CURABLE COATING AGENT FOR THE PRODUCTION OF MULTI-LAYER PAINTINGS IN VEHICLE PAINTING

摘要

This invention relates to radiation-curable coating compositions which containA) compounds having one or more free-radically polymerisable double bonds which additionally contain at least one further functional group reactive for the purposes of an addition and/or condensation reaction,B) compounds having one or more free-radically polymerisable double bonds, which additionally contain at least one further functional group reactive for the purposes of an addition and/or condensation reaction, wherein the additional reactive functional group is complementary to or reactive towards the additional reactive functional groups of component A),C) optionally at least one monomeric, oligomeric and/or polymeric compound having at least one functional group reactive towards the functional groups from component A) or component B)D) one or more photoinitiators as well asE) optionally solvents, water, pigments and/or extenders as well as conventional lacquer additives,wherein component A) and component B) differ from each other and component C) contains no free-radically polymerisable double bonds. The coating compositions are useful for the production of multilayer lacquer coatings, in particular automotive repair lacquer coating.
