Beschreibung
Zusammenfassung:	The invention relates to a polyisocyanate preparation containing at least one polyisocyanate component A) hydrophilically modified with at least one ionic emulsifier and a solvent component E) consisting of at least one organic solvent, characterized in that the solvent component E) has a content of peroxides of not more than 70 mg/l of H2O2 equivalents, wherein this value is the average peroxide content of all organic solvents present in the solvent component E) and the polyisocyanate component A) and the solvent component E) are present in amounts such that the calculated peroxide content of the polyisocyanate preparation based on the sum of A) and E) is not more than 20 mg/l of H2O2. The invention further relates to the use thereof and to coating compositions and substrates coated with these coating compositions.
