Abstract
The present invention relates to blocked polyisocyanates containing at least one isocyanate group which is reversibly blocked with a monofunctional blocking agent for isocyanate groups and at least one isocyanate group in the form of a thermally stable hydantoin group. The present invention also relates to one-component coating compositions containing these blocked polyisocyanates and compounds containing isocyanate-reactive groups.
