  A polyisocyanate mixture comprising a polyisocyanate component A) having aliphatically and/or cycloaliphatically bonded isocyanate groups and a polyisocyanate component B) having araliphatically and/or aromatically bonded isocyanate groups, characterized in that the polyisocyanate component A)comprises at least 0.85% by weight of sulfonate groups (calculated as SO 3; molar weight = 80 g/mol) in chemically bonded form and the proportion of the polyisocyanate component B) is 7 to 43% by weight of the total amount of the components A) and B). Also provided the use thereof and coating compositions comprising the polyisocyanate mixture, and the substrates coated with these coating compositions.
