Abstract
This invention relates to NCO-containing reaction products blocked at the NCO groups by 1-H-pyrazole or derivatives thereof, wherein the NCO-containing reaction products are reaction products of (A) one or more aromatic polyisocyanates, (B) one or more NCO-reactive compounds containing sulfonate and/or tert-amino groups, and (C) optionally, one or more further NCO-reactive compounds other than compounds (B), which are useful for treating substrates, especially textiles, paper, or leather.
