  • Aqueous polyurethane dispersion comprising a terephthalic acid polyester
    Patent number: 9790317
    Abstract: The present invention relates to an aqueous polyurethane dispersion obtainable by the reaction of at least: (A) one polyisocyanate with two or more isocyanate groups, (B) one polyester component comprising (B1) a polyesterpolyol with a mean molecular weight of 300 to 900 g/Mol, having structural units derived from terephthalic acid, (C) one ionic group introducing compound with at least one sulphonate and/or carboxylate group and at least one isocyanate reactive group, (D) one diol with a mean molecular weight of 62 to 400 g/Mol, (E) one polyol with a mean molecular weight of 62 to 400 g/Mol, having three or more hydroxyl groups, (F) one amino functional and/or aminohydroxyl functional compound, its use to coat a substrate and a coating obtained by using the dispersion.
