Patent ID: 8298679

Claim:
A composition containing substantially water-soluble, bis-aminofunctional silicon compounds and water, the silicon compounds being derived from alkoxysilanes and having crosslinking structural elements which form chain-like, cyclic, crosslinked and/or three-dimensionally crosslinked structures, at least one structure in idealized form corresponding to the general formula I, (R 2 O)[(R 2 O) 1-x (R 3 ) x Si(B)O] b [(Y) 2 Si(A)Si(Y) 2 O] a [Si(C)(R 5 ) y (OR 4 ) 1-y O] c [Si(D)(R 7 ) u (OR 6 ) 1-u O] d [Si(E)(R 8 ) v (OR 9 ) 1-v O] w R 9 .(HX) e (I), in the structural elements derived from alkoxysilanes, with A corresponding to a bisaminoalkyl radical, B corresponding to an aminoalkyl radical, C corresponding to an alkyl radical, D corresponding to an epoxy or ether radical and E corresponding to an organofunctional radical, Y corresponding to OR 1 or, in crosslinked and/or three-dimensionally crosslinked structures, independently of one another, OR 1 or O 1/2 , R 1 , R 2 , R 4 , R 6 and/or R 9 substantially corresponding to hydrogen and R 3 , R 5 , R 7 and/or R 8 corresponding to organofunctional radicals, and HX being an acid, in which X is an inorganic or organic acid radical, with 0≦x≦1, 0≦y≦1, 0≦u≦1, a≧1, b≧0, c≧0, d≧0, w≧0, e≧0 and (a+b+c+d+w)≧2, and the composition being substantially free of organic solvents and releasing substantially no more alcohol on crosslinking.
