Claim Text:
1. A two-component composition consisting of two components C1 and C2, the component C1 containing at least one polymer having isocyanate groups; and the component C2 containing an aldimine-containing emulsion comprising: a) at least one dialdimine of the formula (I), in which R represents the radical of an aldehyde ALD after removal of an aldehyde group; A represents the radical of a diamine DA having two primary aliphatic amino groups after removal of the two primary aliphatic amino groups; Q represents the radical of a diisocyanate DI after removal of both isocyanate groups; n represents 0 or represents an integer from 1 to 15; and in which A and R have no groups which are reactive with isocyanate groups in the absence of water, wherein the dialdimine of formula (I) is prepared by a process comprising the step of reacting a diisocyanate DI with a dialdimine of the formula (IV), in the presence of water, the diisocyanate DI and the dialdimine of the formula (IV) being reacted in the molar ratio of [diisocyanate DI]/[dialdimine of the formula (IV)] of <1, and the amount of water being chosen so that the molar ratio [water]/[diisocyanate DI] is ≧2; and b) water, wherein the two-component composition consisting of two components C1 and C2 is an emulsion when mixed.
