    Abstract: Curable binders obtained by simultaneous reaction of A) urethanes or ureas, B) acrylic or methacrylic compounds containing hydroxyl groups, C) paraformaldehyde and D) if appropriate, polyols, wherein, in the case where no polyol D) is also reacted, the reaction is carried out in the presence of an acid ion exchanger, and in the case where a polyol D) is also reacted, the reaction is carried out in the presence of an acid ion exchanger or a strong acid. These binders are suitable as coating compositions which can be cured by electron beams or by UV light.

    Abstract: An aqueous filler composition containing a polyester resin which is built up from the starting materials (a), (b), (c), (d) and (e) or ester-forming derivatives thereof, where the sum of the reactants corresponds to 100 mol% and the ratio between the sum of the hydroxyl equivalents (eq of OH) and the sum of the carboxyl equivalents in the reactants is between 0.5 and 2.0, where (a) is at least one dicarboxylic acid which is not a sulpho or phosphorus monomer, (b) from 0 to 15 mol% of at least one difunctional sulpho or phosphono monomer whose functional groups are carboxyl or hydroxyl groups, containing at least one sulphonate or phosphonate group, (c) at least one difunctional compound which is derived from a glycol containing two -C(R)2-OH groups, (d) up to 40 mol% of a higher-functional compound (functionality > 2) whose functional groups comprise hydroxyl and/or carboxyl groups, and (e) from 0 to 20 mol% of a monofunctional carboxylic acid, where the radicals R in (c) may be, independently of one another, hydrogen, C1-C4-alkyl or C6-C10-aryl, the amounts of free hydroxyl groups are between 30 and 350 milliequivalents of OH/100 g, preferably between 100 and 250 meq of OH/100 g, and the content of free neutralised and/or neutralisable acid groups, in particular sulphonic, phosphonic or carboxyl groups, is between 5 and 350 meq of acid groups/100 g, preferably between 9 and 120 meq of acid groups/100 g.

    Abstract: An aqueous coating composition which contains at least one water-dispersible polyurethane resin containing air-drying groups and optionally further binder resins and conventional (paint) additives, characterised in that the polyurethane resin contains units derived from (A) polyisocyanates, (B) polyols containing air-drying groups, optionally (C) polyols containing no air-drying groups, (D) compounds containing at least two groups which are reactive towards isocyanate groups and containing at least one group which is capable of forming anions, (E) monoalcohols containing air-drying groups, and/or (F) compounds which are different from (B), (C), (D) and (E) and contain at least one group which is reactive with NCO groups. This coating composition has excellent pigment compatibility, and the coatings produced therefrom provide good corrosion protection and have good mechanical properties, even without addition of a siccative.

    Abstract: Water-thinnable two-component coating composition A water-thinnable two-component coating composition, comprising 1) a polyisocyanate component and 2) a polyester resin which is composed of the starting components (a), (b), (c), (d) and (e) or their ester-forming derivatives, the ratio of the sum of the hydroxyl equivalents to the sum of the carboxyl equivalents in the reactants being between 1:0.5 and 1:2.0, where (a) is at least one dicarboxylic acid which is not a sulfo monomer, (b) is 0 to 15 mol% of at least one difunctional sulfo or phosphono monomer, whose functional groups are carboxyl and/or hydroxyl groups, with at least one sulfonate or phosphonate group, (c) is at least one glycol, (d) is 0 to 40 mol% of a higher-functional compound (functionality >2), whose functional groups are hydroxyl and/or carboxyl groups, and (e) is 0 to 20 mol% of a monofunctional carboxylic acid, the amounts of free hydroxyl groups being between 30 and 350 milliequivalents of OH/100 g and the content of free neutralized and/or neutralizable acid groups being between 5 and 350 meq/100 g. These coating compositions are suitable in particular for the preparation of primers, fillers, topcoats and onecoat finishes.
