Dialdimine compounds (I) are new. Dialdimine compounds of formula (R-CH=N-A-NH-(C(=O)-NH-Q-NH-C(=O)-NH-A-NH) n-C(=O)-NH-Q-NH-C(=O)-NH-A-N=CHR) of formula (I) are new. R : an aldehyde residue after the removal of an aldehyde group; A : a diamine residue with two primary aliphatic amino groups after the removal of both primary aliphatic amino groups; Q : diisocyanate residue after the removal of both isocyanate groups; and n : 0 or 1-15. Where A and R exhibit no groups, which in absence of water are capable of reacting with isocyanate group. Independent claims are included for: (1) preparing (I); (2) an aldimine containing emulsion comprising (I), water and optionally at least a surfactant; (3) a two component composition comprising two components K1 and K2, where the component K1 contains at least a polymer exhibiting isocyanate groups, preferably at least a polyurethane polymer exhibiting isocyanate group, and the component K2 contains (I) or an aldimine-containing emulsion; (4) a mixed or partly-mixed two-component composition comprising the component K1 and the component K2 of the two-component composition, which are mixed homogenously or in-homogeneously with one another, where the mixing of the two components preferably takes place over a static mixer or a dynamic mixer; (5) adhering substrates (S1) and (S2) comprising either applying the two-component composition, during mixing or after mixing the two components K1 and K2, on the substrate (S1) and contacting the applied composition with the substrate (S2), or applying the two-component composition, during mixing or after mixing the two components K1 and K2, on a substrate (S1), applying the two-component composition during mixing or after mixing the two components K1 and K2, on the substrate (S2) and contacting the composition applied on the substrate (S1) with the composition applied on the substrate (S2), where the substrate (S1) and (S2) are same or different from each other; (6) sealing the substrates (S1) and (S2) comprising applying the two-component composition during mixing or after mixing the two components K1 and K2 between the substrates (S1) and (S2); (7) producing a coating, preferably a floor covering, comprising applying the two-component composition during mixing or after mixing the two components K1 and K2, on the substrate (S1); and (8) an article, which is glued, adhered or coated by the above method. |
