Abstract:
A compound having an isocyanate group content (calculated as NCO, MW 42) of 0.2 to 20% by weight and an alkoxysilane group content (calculated as Si, MW 28) of 0.2 to 4.5% by weight, wherein the preceding percentages are based on the weight of the compounds, and containing sufficient chemically incorporated hydrophilic groups to form a stable dispersion in water, wherein the alkoxysilane groups are incorporated as the reaction product ofi) a polyisocyanate component having a minimum average functionality of 2.4 and containing at least 50% by weight of a polyisocyanate adduct andii) an amino compound corresponding to formula I ##STR3## wherein X represents identical or different organic groups which are inert to isocyanate groups below 100.degree. C., provided that at least one of these groups is an alkoxy group,R.sub.1 represents an organic group which is inert to isocyanate groups at a temperature of 100.degree. C. or less, andn is an integer from 1 to 8.
