Aqueous binder dispersion for physically drying coating agents and their use. The invention relates to an aqueous binder dispersion for physically drying coating agents, which contains a mixture of A) 20 -80 wt.% of one or more, carbonate group-containing polyurethanes with a number average molecular weight (Mn) of 70,000 to 500,000 in the form of an aqueous dispersion, and B) 20 - 80 wt.% of one or more carbonate group-free and preferably urea group-free polyurethane resins containing ionic groups, with a number average molecular weight (Mn) of 10,000 to 300,000 and an acid value of 5 to 50, in the form of an aqueous dispersion, the wt.% of the components A) and B), in each case referred to the resin solids, amounting to 100%.

L'invention porte sur une dispersion aqueuse de liant pour agents de revêtements séchant physiquement et leur emploi. La dispersion renferme un mélange de : A) 20 à 80 % en poids d'un ou de plusieurs polyuréthanes renfermant le groupe carbonate, de masse molaire moyenne 70 000 à 500 000, sous la forme de dispersion aqueuse; B) 20 à 80% en poids d'une ou de plusieurs résines de polyuréthanes exemptes de groupe carbonate ainsi que, de préférence, de groupe urée, mais renfermant des groupes ioniques, avec une masse molaire moyenne de 10 000 à 300 000 et un indice d'acide de 5 à 50, sous forme de dispersion aqueuse; le % en poids des constituants A) et B), dans chacun des cas se rapportant aux solides à base de résine, s'établissait à 100 %.
