Disclosed are alkyd resin emulsions for coating varnishes, containing a water-insoluble alkyd resin A and a water-soluble alkyd resin B that is used as an emulsifying resin and represents an esterification product of an alkyd resin Ba which can be homogeneously mixed with the alkyd resin A at a weight ratio (Ba to A) ranging between 2:98 and 50:50, alkyd resin A being the resin that is to be emulsified, and an adduct Bb of a C1-C4 alkoxy polyethylene glycol Bba and a cycloaliphatic dicarboxylic acid anhydride Bbb at a mole ration (Bba to Bbb) ranging between 09.95:1.05 mol/mol and 1.05:0.95 mol/mol. Also disclosed is a method for the production thereof, the use thereof for coating substrates selected among textiles, mineral materials, metals, and wood.
Alkyd resin emulsions for topcoats comprising a water-insoluble alkyd resin A and a water-soluble alkyd resin B, which is used as an emulsifying resin and is an esterification product of an alkyd resin Ba, which has a hydroxyl number of at least 30 mg/g, and is homogeneously miscible with the alkyd resin A to be emulsified at least in a mass ratio range of Ba to A of from 2:98 to 50:50, and an adduct Bb of a C1-C4-alkoxypolyethylene glycol Bba and a cycloaliphatic dicarboxylic acid anhydride Bbb in a ratio of amounts of substance of Bba to Bbb of from 0.95:1.05 mol/mol to 1.05:0.95 mol/mol.
