Japanese Patent JP5351138

B2

Isocyanate and aldimine group-carrying compounds (I), are new. Isocyanate and aldimine group-carrying compounds of formula ((OCN) u-Q-(NH-C(=O)-NH-X-N=CH-Y 1>) v) (I), are new. Q : polyisocyanate with (u+v) terminal isocyanate group after removing all isocyanate group; u, v : 1 or 2; Y 1> : a group of formula (-C(Y1a)(Y 2>)(Y 3>)) (Ia) or (-Y 4>) (Ib); either Y1a, Y 2> : univalent 1-12C-hydrocarbon; or Y1aY 2> : 4-20C-bivalent hydrocarbon, whose one part is optionally substituted by 5-8, preferably 6C carbocyclic rings; Y 3> : a univalent hydrocarbon optionally exhibiting at least a heteroatom, preferably O in the form of ether, carbonyl or ester; Y 4> : optionally substituted (hetero)aryl group, which has a ring size of 5-8, preferably 6, C(=O)-R 1>, or optionally substituted alkenyl- or arylalkenyl group with at least 6C; R 1> : H or an alkoxy; and X : a diamine with two primary amino group after the removal of these two amino group. Provided that: at least one of both primary amino group of the diamine is an aliphatic amino group and the two primary amino group of the diamine is either in the amount of the hydrogen atoms at the alpha position of the alpha -carbon atoms of the respective amino group, or in the amount of the hydrogen atoms at beta position of the beta -carbon atoms of the respective amino group Independent claims are included for: (1) preparing (I); (2) a composition (A) comprising (I) and at least a polyisocyanate; (3) a hardening composition, obtained by the reaction of (A) with water, preferably in the form of humidity; (4) process for adhering a substrate (S1) with a substrate (S2) comprising either applying (A) on the substrate (S1) and contacting substrate (S1) having the applied composition with the substrate (S2) within the exposed time of (A), or either applying (A) on the substrate (S1) and substrate (S2) and contacting the applied composition within the exposed time of (A), where the substrate (S2) is from same or different material of substrate (S1); and (5) reducing the diisocyanate monomer in isocyanate group containing polyurethane polymer or in oligomer polyisocyanate or in (A) containing the polyurethane polymer comprising reacting polyaldimine compound (VI) of formula (Xa-(N=CH-C(Y 1>)(Y 2>)(Y 3>)) n) (VIa) or (Xa(-N=C-Y 4>) n) (VIb) in the presence of an under-stoichiometric quantity of water, preferably less than 0.5 mol water/equivalent of aldimine group. Xa : a polyamine with n primary amino group after the removal of the n-amino group; and n : 2-6, preferably 2.
