摘要

Producing aqueous coating compositions curable acids, in particular for coating finish films and continuous edges, and which contain an aminoplast resin and a polyester containing hydroxyl groups, from: a) 30 to 50 mol% of a mixture of a1) 50 to 100 mole% of saturated aliphatic dicarboxylic acids; a2) 0 to 50 mol% of olefinically unsaturated aliphatic dicarboxylic acids; a3) 0 to 50 mole% of aromatic dicarboxylic acids; a4) 0 to 50 mole% of diisocyanate; and b) 70 to 30% by moles of a mixture of b1) from 10 to 60 mol% of at least one glycol monomer and / or oligomer having 2 to 4 carbon atoms per glycol segment and a number average molecular weight less than or equal to 200; b2) 10 to 60 mol% of at least one diol having 4 to 10 carbon atoms per molecule, with the exception of the aforementioned glycols and b3) 0 to 70 mol% of at least one polyol having on average 3 to 6 hydroxyl groups per molecule and a number average molecular weight less than or equal to 1000.
