Abstract

The present invention relates to a use of at least one homopolymer or copolymer which is obtainable by polymerizing ethylenically unsaturated monomers and which is composed of at least one structural unit (W0) or of at least two structural units (W1) and (W2) differing from one another, and also optionally of at least one other structural unit (W3) differing from (W0), (W1) and (W2), where each structural unit (W0) contains not only at least one functional group comprising at least one phosphorus atom, but also at least one functional group reactive towards an isocyanate group, each structural unit (W1) has at least one functional group having at least one phosphorus atom, each structural unit (W2) has at least one functional group reactive towards an isocyanate group, where none of the structural units (W2) comprises phosphorus atoms, and the homopolymer or copolymer contains, relative to the total quantity of the at least one structural unit (W0) within the main polymer chain of the homopolymer or copolymer, from 1 to 100 mol % of the structural units (W0) or, relative to the total quantity of the at least two structural units (W1) and (W2) within the main polymer chain of the homopolymer or copolymer, from 1 to 80 mol % of the structural units (W1) and from 1 to 80 mol % of the structural units (W2), as adhesion-strengthening additive, a coating composition containing this type of homopolymer or copolymer as component (A) and at least one binder as component (B), and also a use of this coating composition as clearcoat, on production lines, for rehabilitation, or for maintenance.
