摘要： The present invention relates to a process for preparing aqueous binders f or aqueous coating compositions by reacting a mixture of A) 9.9 to 85 wt.% of a hydroxy- and acid-functional poly(meth)acrylate a nd B) 14.9 to 90 wt.% of a hydroxy-functional, fatty acid-modified polyeste r with C) 0.1 to 20 wt.% of a diisocyanate having a molecular weight of 140 to 31 8, to form urethane groups and then dissolving or dispersing the reaction produ ct in water with prior or simultaneous neutralization of at least a portion of the carboxyl groups present, wherein the sum of the percentages of A) to C) add up to 100 . The present invention also relates to the aqueous binders obtained by th is process and their use, optionally combined with other oxidatively drying lacquer resins, in air- and/or heat-drying, two-component coating compositions, preferably aqueous polyurethane coating compositions, or in combination with optionally blocked polyisocyanates and/or amino cross-linking agents in aqueous heat- curing coating compositions.

摘要： Aq., crosslinkable binder dispersions (A) with a low solvent content, an acid no. of 8-45 mg KOH/g solid, an OH no. of 25-200 and a solids content of more than 35%, contg. (w.r.t. solids) (A1) 2-30 wt% OH-functional polyether(s) with a functionality of 1.8-6.0, a mol. wt. of 152-4000 and an OH no. of 50-700 mg KOH/g, (A2) 35-90 wt% OH-functional copolymer with an OH no. of 20-220 and an acid no. of 0-50, derived from (b1) (meth)acrylate esters and/or vinylaromatics, (b2) OH-functional monomers, (b3) other monomers and opt. (b4) acid-functional monomers, and (A3) 5-60 wt% OH- and COOH-functional copolymer with an OH no. of 30-220 and an acid no. of 25-200, derived from monomers (b1)-(b4) as above, in which the acid no. of (A3) is higher than that of (A2). Also claimed are (i) aq. binder combinations contg. 55-97 wt% dispersion (A) and 3-45 wt% amino resin and/or blocked polyisocyanate as crosslinker, esp. 2-component binders contg. 55-97 wt% (A) and 3-45 wt% polyisocyanate(s) with free NCO gps. and opt. hydrophilic gps., and (ii) a process for the prodn. of (A), by polymerising monomers (b1)-(b4) in presence of (A1) in amts. as above to form copolymer (A2), polymerising (b1)-(b4) to form (A3), converting 40-100% of the COOH gps. into carboxylate by adding a neutralising agent, and dispersing in water to give (A) with a solids content of more than 35 wt% and an organic solvent content of less than 6 wt%..
