摘要： This invention relates to a composition, and to the preparation and use of thereof said composition being suitable as a rheology influencer for coating media and comprising the reaction product formed by reaction of a mixture of components A, B and C with components D, E and F. Components A, B and C form a mixture wherein component A is one or more (meth)acrylic copolymers and/or one or more polyesters which contain hydroxyl groups. Component B is a copolymer of ethylhexyl (meth)acrylate and one or more hydroxyalkyl (meth)acrylates, as well as .alpha.,.beta.-unsaturated monomers which are different therefrom. Component C is a hydroxy--functional microdispersion which is produced by polymerizing hydroxylalkyl (meth)acrylates in combination with unsaturated monomers in a mixture of polyesters or polyacrylates containing carboxyl and/or hydroxyl groups. Component D is one or more aliphatic polyisocyantes and component E is .epsilon.-caprolactam. The caprolactam partially blocks the polyisocyanate. The component F is one or more primary amines. These ingredients are combined in certain specified amounts. The invention also relates to coating media and to the production of these coating media, which contain said composition as a rheology influencer.
