Patent

CA 2254603

The present invention relates to storage stable, aqueous polyurethane- polyacrylate hybrid dispersions, which are self crosslinkable at room temperature and contain A) 10 to 95 wt.%, of a polyurethane dispersion, B) 5 to 90 wt.%, of a polymer prepared in the presence of component A) from a mixture of vinyl monomers containing 0.5 to 20 wt.%, based on the total resin solids content of the hybrid dispersion, of a vinyl monomer containing acetoacetoxy groups and C) an at least difunctional primary or secondary amine, which is present in an equivalent ratio of amino groups to acetoacetoxy groups of 0.5:1 to 1.1:1, in which the wt.% of components A) and B) add up to 100, based on the total weight of components A) and B). The present invention also relates to one-component coating compositions containing these hybrid dispersions as binders and to substrates coated with these coating com-positions.
