    Abstract: The dispersions (I), free from hydrophilic auxilaries, with less than 5% organic solvent and contg. a polymer comprising 15-50 wt.% specified component A and 50-85 wt.% specified component B, where sum of % of A and B = 100, are prepd. by polymerising to form one of A and B in an organic solvent, polymerising to form the other in the polymer soln., dispersing the mixt. of A and B in water with addn. of NH3, and opt. then distilling off excess solvent. A is copolymer of 1) 85-98.5 wt.% at least one (meth)acrylate ester with a 1-20C monoalkanol without further functional gps., opt. up to 60 wt.% ester being replaced by a vinylaromatic cpd. 2) 1.5-15 wt.% at least one copolymerisable olefinically unsatd. 3-10C organic cpd. with at least one COOH or carboxylic acid anhydride gp., 3) 0-30 wt.% copolymerisable, olefinically unsatd. organic cpd., other than those under 1) or 2), and free from COOH and carboxylic acid anhydride gps., where sum of % of 1) and 2) = 100. B is copolymer of 1) and 3) exclusively. A is prepd. with less than 10 wt.% vinylaromatic cpd. acid no. of A is max. 75 mg KOH/g solids, and acid no. of mixt. of A and B is max. 30 mg KOH/g solids. Or A is prepd. with 10-60 wt.% vinylaromatic cpd., acid no. of A is max. 95 mg KOH/g solids, and acid no. of mixt. of A and B is max. 50 mg KOH/g solids. Polymer compsn. of A and B is chosen such that (I) dries at room temp. without further addns. to clear, nontacky film.

    Abstract: Coatings (I), contg. less than 15 wt.% organic solvent, contain as binder a mixt., dispersed in water, of A) 45-2 wt.% at least one water-insol., oxidatively drying, fatty acid -modified alkyd or urethane resin with acid no. under 20 mg KOH/g, condensed fatty acid content at least 50 wt.%, and viscosity under 100 Pa-s. B) 55-98 wt.% at least one physically drying polymer resin dispersable in water through addn. of NH3, opt. with addn. of volatile alcohols or glycol ethers, where sum of % under A and B = 100. Prepn. of (I) by dispersing in A at least one pigment and/or filter, opt. with volatile organic solvent and/or plasticiser, and opt. other water-insol. paint resin, then mixing with aq. soln. or dispersion of B. Binder comprises 30-5 wt.% A, 70-95 wt.% B. A has acid no. under 15 and contains at least 60 wt.% condensed fatty acid. B is (meth)acrylate ester copolymer (II) or (II) mixt. with styrene content up to 30 wt.% and acid no. 10-60 mg KOH/g copolymer or is styrene-(meth)acrylate ester copolymer (III) or (III) mixt. with polymerised styrene content 30-70 wt.% and acid no. 25-90 mg KOH/g copolymer. (I) contains 2-50 wt.%, on A + B, at least one water-immiscible, heat-curable resin stable at room temp..
