A composition comprising a self-emulsifiable or self-dispersible aqueous
solution or dispersion of at least one urea linkage-containing
alkoxypolyoxyalkylene fluorocarbamate prepared by contacting (a) at least
one polyisocyanate which contains at least three isocyanate groups per
molecule, (b) at least one fluorochemical reagent of the formula
F(CF2)aCH2CH2OH, wherein a is 4, 6, or 8, or mixtures thereof, provided
that a is a maximum of 50% of 8, and (c) at least one hydrophilic,
water-solvatable reagent which contains per molecule a single functional
group which has at least one reactive Zerewitinoff hydrogen atom, and
thereafter with (d) water, the equivalent weight of the polyisocyanate
and the reagents (b) and (c) being such that the reagents react with 55%
to 95% of the isocyanate groups, and water reacts with all of the
remaining isocyanate groups, the composition imparting durable
hydrophilicity and stain release properties to a substrate treated
therewith is disclosed.
