Abstract: Aldimine compounds (I), are new. Aldimine compounds of formula ((HX) m-A-(N=CH 2-C(R 1>)(R 2>)-CH(R 3>)-N(R 4>)(R 5>)) n) (I), are new. Either A : an aliphatic amino group after removing n primary aliphatic amino group and m HX group; or AR 7> : (n+2)-valent 3-20C hydrocarbon, which optionally contains an heteroatom, preferably in the form of ether-oxygen or tertiary amine nitrogen; n : 1-4; m : 0-4; either R 1>, R 2> : an univalent 1-12C hydrocarbon; or R 1>R 2> : a bivalent 4-12C hydrocarbon (whose one part is optionally substituted by carbocyclic ring with 5-8, preferably 6C); R 3> : H, 1-12C-alkyl, -arylalkyl or -alkoxycarbonyl; either R 4>, R 5> : CH 3or an univalent aliphatic, cycloaliphatic or arylaliphatic residue with 2-12C, which optionally contains one OH group, and heteroatoms in the form of ether-oxygen or tertiary amine nitrogen; or R 4>R 5> : a bivalent 4-12C aliphatic residue containing at least one OH, whose one part is optionally substituted by heterocyclic ring with 5-8, preferably 6 ring atoms, where the ring optionally contains further heteroatom in the form of ether-oxygen or tertiary amine nitrogen, when R 4>contains at least one OH group; X : O, S, N-R 6>or N-R 7>; R 6> : an univalent 1-20C hydrocarbon optionally containing at least a carboxylic acid ester-, nitrile-, nitro-, phosphonic acid ester-, sulfone- or sulfonic acid ester-groups, or an aldimine moiety of formula (-B1-(N=CH 2-C(R 1>)(R 2>)-CH(R 3>)-N(R 4>)(R 5>)) p); p : 0 or 1-10000; and B1 : (p+1)-valent hydrocarbon, which optionally contains ether-oxygen, tertiary amine nitrogen, OH, secondary amino or mercapto group. Independent claims are included for: (1) the preparation of (I); (2) an aldimine compound of formula ((HX 2>) m-A-(N=CH 2-C(R 1>)(R 2>)-CH(R 3>)-N +>(R 4>)(R 5>)(R 10>)) n) (IX), obtained by protonating or alkylating (I); (3) a hardenable composition comprising at least a polyisocyanate and (I) or (IX); (4) a hardened composition obtained by the reaction of the hardenable composition and water, preferably in the form of moisture; (5) a process for adhering a substrate S1 with a substrate S2 comprising applying the hardenable composition on the substrate S1 and contacting the applied composition with the substrate S2 within the open time of the composition, or applying the hardenable composition on the substrate S1 and substrate S2 and contacting the applied composition together within the open time of the composition, where the substrate S2 consists of same or different material of the substrate S1; (6) a process for sealing the substrates S1 and S2 comprising applying the hardenable composition between the substrate S1 and the substrate S2, such that the composition contacts with the substrate S1 and the substrate S2; and (7) a process for coating the substrate S1 comprising applying the hardenable composition on the substrate S1 within the open time of the composition. R 10> : H, 1-20C-alkyl, -cycloalkyl or -arylalkyl; X 2> : O, S, N-R 11>or N-R 7>; and R 11> : an univalent 1-20C hydrocarbon optionally containing at least a carboxylic acid ester-, nitrile-, nitro-, phosphonic acid ester-, sulfone- or sulfonic acid ester-group, or an aldimine moiety of formula (-B1-(N=CH 2-C(R 1>)(R 2>)-CH(R 3>)-N +>(R 4>)(R 5>)(R 10>)) p).
