Abstract: The invention relates to a process for the preparation of an aqueous dispersion of an anionic polyurethane in which initially a tertiary aminofunctional acrylic monomer is used as neutralizing agent for pendant carboxylic acid groups in dispersions of a polyurethane or a polyurethane/polyacrylate, whereafter the unsaturated monomers undergo in situ an addition polymerisation, optionally together with other unsaturated monomer. In the process the isocyanate terminated prepolymer may be reacted with 0-100% of a stoichiometric amount of a hydroxy functional unsaturated monomer before the dispersion in water. The tertiary amine functional usaturated monomer is preset in a ratio to the anionic residues to be neutralized in the polyurethane prepolymer from 0.3 to 2 and preferably from 0.7 to 1.5. Furthermore the amount of carboxylic acid functions in the isocyanate functional polyurethane prepolymer is from 1 to 15% and preferably from 2 to 10%. The invention also relates to dispersions prepared by the present process and to a coating or film obtained from said dispersion.

Abstract: The invention relates to an aqueous dispersion of a crosslinkable polyurethane obtained by chain extension of a polyurethane prepolymer with a compound containing hydrazone functions having general formula (1), wherein Q1 and Q2 is a hydrazone functional group of formula (2), H or R1, R and R1 in formula (1) is an organic group which has no reactivity towards the hydrazone function, R2 and R3 in formula (2) is an organic group which has no reactivity towards the hydrazone function or H, x has a value from 1 to 10, and is preferably from 1 to 4 with the proviso that at least one of the groups Q1 or Q2 is of formula (2). The invention relates also to a process for a preparation of an aqueous dispersion of a crosslinkable polyurethane containing hydrazne functions, and to the application of the aqueous dispersion of a crosslinkable polyurethane together with a polyisocyanate, a polyketone-or a polyepoxide-functional material onto a substrate.
