Abstract: The invention relates to the use of crosslinked polymer microparticles having an average particle size of at most 5 mu m and a glass transition temperature (Tg) of at least +30 DEG C. in aqueous paint preparations as filler and/or as partial substitute of white pigments, in particular of titanium dioxide. Among other things, the corresponding paints show increased spreading power, less tendency for sedimentation and reduced crater formation.

Abstract: Copolymers of particularly low viscosity which can be prepared by bulk polymerisation in which component (A) is introduced at the beginning of the polymerisation and at least two olefinically unsaturated, copolymerisable monomers (B), of which at least one contains at least one COOH group and at least one is sterically hindered, are added during the further course of the polymerisation.

Abstract: Water-dilutable dispersions of acrylate copolymers having a hydroxyl number of from 40 to 200 mg of KOH/g and an acid number of from 15 to 50 mg of KOH/g, obtained by free-radical copolymerization of a) from 5 to 40 parts by weight of at least one glycidyl ester of an aliphatic, saturated monocarboxylic acid which is branched in the alpha -position, b) from 0 to 30 parts by weight of at least one diester of an alpha , beta -olefinically unsaturated dicarboxylic acid, c) from 0 to 70 parts by weight of at least one vinyl aromatic hydrocarbon, where the molar amount of component c) is always greater than or equal to the molar amount of component b), d) from 0 to 60 parts by weight of an alkyl ester of an alpha , beta -olefinically unsaturated carboxylic acid, e) from 2 to 40 parts by weight of at least one alpha , beta -olefinically unsaturated carboxylic acid, where the molar amount of component e) is always greater than the molar amount of component a), f) from 5 to 40 parts by weight of at least one hydroxyalkyl ester of an alpha , beta -olefinically unsaturated carboxylic acid, where the polymerisation is carried out in the presence or absence of solvents, optionally with addition of a water-dilutable solvent, neutralisation and dilution with water. These dispersions are suitable as water-dilutable binders for stoving (baking) varnishes or stoving solid-colour top coats.

Abstract: A curing agent (A) containing active CH groups is characterised in that it contains at least two groups of the formula (I) or structural units of the formula (I') or (I") in which A is X and Y are identical or different and are CO2R , CN, NO2, CONH2, CONR H or CONR R , where the radicals R may be identical or different and are hydrocarbon radicals, preferably alkyl radicals having 1 to 12 carbon atoms, which may also be interrupted by oxygen or an N-alkyl radical, with the proviso that only one of the two radicals X and Y may be an NO2 group; A' is X' and Y' are identical or different and are Curable mixtures of (A) and a Michael acceptor (B) and optionally diluents and conventional additives cure rapidly even at low temperatures and are particularly suitable for surface-coating compositions.
