The present invention relates to a mixture comprising (A) at least one polyisocyanate (a), (B) at least one emulsifier obtainable by reacting at least one polyisocyanate with at least one polyether alcohol, The polyether alcohol has a molecular weight of less than 400 g/mol, (C) at least one emulsifier obtainable by reacting at least one polyisocyanate with at least one polyether alcohol having a molecular weight greater than 450 g /mol, and (D) optionally at least one emulsifier, which can interact with at least one hydrophilic non-isocyanate-reactive group (group D1 ) and exactly one isocyanate-reactive group via a polyisocyanate Compound (d) of (group D2) is obtained by reaction; wherein the weight ratio of component (B) to component (C) is 30:70 to 70:30, preferably 40:60 to 60:40. |
