Abstract: Described herein is a bismuth-containing catalyser, which is defined by a general formula (I). The bismuth-containing catalyser includes at least one radical R1, which includes a carboxyl fragment according to the general formula (II), where a first carbon atom (?-carbon) is bonded to the carbon atom of the carboxyl group, which in turn is directly substituted with at least one aromatic system. Also described herein is a method for preparing the bismuth-containing catalyser and a method of using the bismuth-containing catalyser for preparing compounds including a urethane group.

Abstract: A coating material system including components (A) to (C) and also, optionally, further components, with, in a first option, all components (A) to (C) and also, where present, the further optional components being present separately from one another, in other words the individual components not being mixed with one another. In a second option of the coating material system, conversely, the aforementioned components may also be mixed wholly or at least partly with one another. Where the components are at least partly mixed with one another, for example, component (C) is mixed with component (A), while component (B) is present separately from this mixture of (A) and (C). Optionally, component (B) may also be mixed with a portion of component (C). Furthermore, the mixtures of (A) and (C) and of (B) and (C) may additionally include at least one optional component such as a solvent, for example.
