Aqueous dispersions for textile finishing

An aqueous textile fabric treating dispersion comprising at least two components A) and B), component A) being a compound containing two or more blocked isocyanate groups in the molecule, wherein component B) is a product obtained by reacting a diepoxy compound of the formula (I)

• G—O—(L—O)y—G (I)
• or a mixture of compounds of the formula (I) with a diamine or polyamine of the formula (II)
• H2N—(CjH2jNH)z—H (11)
• or a mixture of compounds of the formula (II) in a proportion such that the molar ratio of the deployed glycidyl radicals G to the hydrogen atoms of the deployed amino groups is in the range from 2:1 to 1:4, and subsequently reacting the resulting reaction product with an acid in a proportion such that the ratio of moles of nitrogen to equivalents of acid is in the range from 1:0.25 to 1:2, the above radicals and indices independently of one another having the following definitions:
• G is a glycidyl radical (2,3-epoxy-1-propyl radical)
• L is a divalent radical of formula (CO)c1—Ed—(CO)c2
• E is a divalent aromatic, aliphatic or araliphatic hydrocarbon radical of 1-18 carbon atoms uninterrupted or interrupted by one or more oxygen atoms
• c1 and c2 independently of one another=0 or 1
• d=0 or 1 and c1, c2 and d are not all simultaneously 0 when y=1
• j=0 or 2-10
• y=0 or 1 and
• z=1-3;
• but z=1 if j=0.
