Abstract: An aqueous coating composition comprises a) an organic polymer in aqueous solution which carries free or neutralized acid groups, or free and neutralized acid groups, and b) a crosslinker of the structural formula I (see fig. I) where R1, R2, R3 and R4 independently are hydrogen or alkyls, aryls and/or aralkyls of 1 to 24 C atoms, or mixtures of two or more thereof, X is oxygen, sulfur and/or -N(R5)-, where R5 is alkyl, aryl or aralkyl of 1 to 24 C atoms or is hydrogen and Z is an n-functional alkyl, aryl or aralkyl which is unsubstituted or substituted by further groups, and n is a number which is at least 2, wherein the molar mass of the crosslinker is below 10,000.

Abstract: Latent-crosslinking aqueous polyurethane (PU) dispersions, containing (I) a disperse phase (P.I) containing (Ia) a polyurethane (PUR.Ia) with groups which produce the water- dispersibility and also groups containing a C=C double bond activated by a directly attached carbonyl group or (Ib) a mixture of a PU (PUR.Ib) with water dispersibility-producing groups but no activated double bonds as above and a compound (V.I) other than PUR.Ia and PUR.Ib which contains groups with a CO-activated C=C bond as above, and (II) a disperse phase (P.II) containing a compound other than the above which contains several thiol, prim. amino or sec. amino groups. Also claimed are objects made of wood, metal, textile, leather or plastic, which are bonded, impregnated or coated with these PU dispersions.

Abstract: The invention concerns aqueous dispersions containing a polyurethane (A), containing structural units derived from compounds of formula (I), in which the substituents have the following meanings: R1, R2, R3 each designate hydrogen, C1-C24 alkyl or C6 - C24 alkenyl; R4 designates hydrogen; R5, R6 a) together designate C4-C10 alkane-diyl, b) each designate C2-C10 alkyl, C5-C8 cycloalkyl or C7-C20 aralkyl, c) each designate a hydroxyl-terminated poly(C2C4 alkylene oxide), or d) designate an R5 or R6 group with the meaning given in (a) to (c) and the other group designating hydrogen or a group of formula (II), in which X designates C2-C6 alkane-diyl; and R7 has the same meaning as R5 or R6 with the exception that R7 is not a group of formula II, R5 and R6 carrying a total of between 2 and 5 hydroxyl groups bonded to aliphatic carbon atoms; and R5 and/or R6 optionally carrying 1 or 2 aromatically bonded hydroxyl groups or 1 nitrile, tertiary amino, carboxylic acid or sulphonic acid group which are optionally present in the form of their salts.
