    Abstract: Cationic heat-hardenable binders comprising polymers containing amine groups and a crosslinking component which is film-forming with the amine group containing polymer through transesterification at elevated temperatures are described. The binders which are water-dilutable upon protonization of the amine groups comprise(a) 60 to 95% by weight of a polymer having a hydroxyl value of from 40 to 450 mg KOH/g and an amine value of from 20 to 150 mg KOH/g, water-soluble or water-dilutable upon protonation of the basic groups, and(b) 5 to 40% by weight of a cross-linking component of the general formula ##STR1## n having a value of from 1 through 5, R.sub.1 being the moiety of a monoalcohol having from 1 to 8 C-atoms or of a polyol or of a polyamine or of a polyepoxy compound or of a polyisocyanate remaining after reaction with one or more carboxylic acid groups, andR.sub.2 being a straight chain or branched alkyl radical with from 1 to 8 C-atoms.The binders have excellent characteristics particularly when deposited from an electrodeposition system.

    Abstract: Metallic coat finishing with good gloss vividness is provided by undercoating a liquid coating containing a specified thermosetting vinyl copolymer and a metallic appearance imparting pigment, overcoating a thermosetting, clear powder paint and then baking the two coated film together. The specified thermosetting vinyl copolymer is obtained by copolymerizing N-alkoxymethyl(metha)-acrylic amide, a hydroxyl group containing vinyl monomer, a carboxyl group containing vinyl monomer and copolymerizable other vinyl monomers in specified amounts.

    Abstract: An air-cross-linkable lacquer binder comprising a copolymer of copolymerized units of from 10 to 40% by weight of glycidyl acrylate, glycidyl methacrylate or a mixture thereof, and 70 to 10% by weight of at least one other vinyl monomer which has been reacted with (based in each case on the quantity of lacquer binder) of from 0.01 to 30% by weight of at least one wood preservative having at least one glycidyl-reactive hydrogen atom and from 20 to 60% by weight of at least one air-drying natural or isomerized fatty acid and from 0 to 10% by weight of a dicarboxylic acid anhydride, said lacquer binder having an average molecular weight M.sub.n of from 1500 to 15,000 and an acid number of from 3 to 15. One special advantage of the lacquer binder according to the invention is that the wood preservatives are chemically fixed to the polymer molecule so that their release is retarded and the protective action is prolonged. Another advantage is the possibility to prepare well-drying wood preservative systems with lacquers which have not been treated with drying agents.
