Abstract: The present invention relates to acid-curing aqueous coating compositions, in particular for the coating of veneer films and continuous edges, containing an amino resin and a hydroxyl-containing polyester.

Abstract: The present invention relates to acid-curing aqueous coating compositions, in particular for the coating of finish sheeting and continuous edging, which contain aminoplast resin and hydroxyl-containing polyesters, wherein the polyester is prepared froma) 33 to 55 mol % of a dicarboxylic acid component obtained froma.sub.1) 50 to 100 mol % of olefinically unsaturated aliphatic dicarboxylic acidsa.sub.2) 0 to 50 mol % of saturated aliphatic dicarboxylic acidsa.sub.3) 0 to 50 mol % of saturated aliphatic dicarboxylic acids andb) 67 to 45 mol % of a polyol component obtained fromb.sub.1) 20 to 90 mol % of at least one monomeric and/or oligomeric glycol having 2 to 4 carbon atoms per glycol segment and number average molecular weights smaller than 200b.sub.2) 5 to 30 mol % of at least one polymeric glycol having 2 to 4 carbon atoms per glycol segment and a number average molecular weight between 300 and 1000 andb.sub.

Abstract: The present invention relates to a process for coating finish foils and endless edges, wherein an acid-curing aqueous coating composition, on the basis of aminoplast resin/compound containing hydroxyl groups/self-crosslinking acrylate dispersion, is applied and baked in. The coating composition used contains 5 to 20% by weight of one or more fillers of a mean particle size from 0.015 to 10 .mu.m, a maximum particle size of .ltoreq.40 .mu.m and a density of .ltoreq.2.9 g/cm.sup.3.The invention also relates to the coating compositions positions used in the process and to finish foils and endless edges produced by the process, which especially have the advantage of an extremely low formaldehyde emission, particularly as a composite with a low-formaldehyde chipboard.
