Claim:
1. A cationically hydrophilized polyurethaneurea synthesized from a) ≧20 and ≦55 wt % of at least one aliphatic, araliphatic and/or cycloaliphatic polyisocyanate selected from HDI, H12-MDI and/or IPDI, b) ≧20 and ≦50 wt % of polyols having a number-average molecular weight Mn≧400 and ≦6000 g/mol and a hydroxyl functionality of ≧1.5 and ≦4, c) ≧5 and ≦15 wt % of at least one cationically hydrophilizing component selected from N,N′-bis(hydroxyalkyl)alkylamines, d) ≧2 and ≦12 wt % of at least one aliphatic, amino-functional compound which has at least two isocyanate-reactive amino groups, comprising ≧95 wt % of isophoronediamine IPDA, based on the overall mass of component d), e) ≧1 and ≦4 wt % of optionally at least one alcohol which has at least two hydroxyl groups and a molar mass ≧60 and ≦399 g/mol and f) ≧0 and ≦10 wt % of at least one compound which has a group that is reactive towards isocyanate groups, based in each case on the overall mass of the polyurethaneurea, based in each case on the overall mass of the polyurethaneurea, with components a) to f) adding up to 100 wt %.
