Abstract: The invention relates to a coating material which can be hardened thermally and, optionally, by using actinic radiation. Said coating material contains: A) a binding agent comprising at least two functional groups (a1) which can enter into thermal cross-linking reactions with complementary functional groups (b1) in cross-linking agent (B), and; (B) at least one cross-linking agent comprising at least two functional groups (b1) which can enter into thermal cross-linking reactions with complementary functional groups (a1) in binding agent (A). At least one binding agent (A) contains, in an integrally polymerized manner, at least one olefinically unsaturated polysiloxane macromonomer which contains, in the statistical mean, at least 3.0 double bonds per molecule. The invention also relates to the use of the coating material for producing highly scratch resistant multilayer transparent lacquers.

Abstract: An aqueous coating material comprising A) at least one polyester that is water-soluble or water-dispersible, B) at least one polyurethane acrylate that is water-soluble or water-dispersible, C) at least one amino resin that is itself water-soluble or water-dispersible or is water-soluble or water-dispersible in the presence of the polyester and the polyurethane acrylate, D) at least one of a color pigment, an effect pigment, a color and effect pigment, and a filler, and E) optionally at least one polyisocyanate. Also, processes for preparing and using the aqueous coating material.

Abstract: An olefinically unsaturated, hydrophilic or hydrophobic polyurethane, which can be produced as follows: a polyurethane pre-polymer, produced by at least reacting at least one poly-isocyanate with at least one saturated and/or olefinically unsaturated higher-molecular and/or lower-molecular weight polyol in one or more stages so that, according to the statistical mean, at least one free isocyanate group per molecule still remains, is reacted with at least one compound containing at least two functional groups that are reactive to isocyanate, in such a way that no remaining free isocyanate groups are detectable. The resultant polyurethane is then reacted with at least one anhydride of an &agr;,&bgr;-unsaturated carboxylic acid. Also, the use of the polyurethane for producing graft copolymers and to the use of the polyurethane and the graft copolymers for producing coating materials, adhesives and sealing masses.

Abstract: A coating composition consisting of at least four components, comprising a component (I) comprising at least one oligomeric or polymeric resin containing functional groups which react with isocyanate groups, as binder (A), a component (II) comprising at least one polyisocyanate as crosslinking agent (F), a component (III) which comprises water and is substantially free from acrylate copolymers (A) dispersed or dissolved therein, and a finely divided solid component (IV) which comprises at least one water-soluble or -dispersible finely divided solid acrylate copolymer (A); and also a process for producing a coating from a coating composition consisting of at least four components, which involves (1) mixing at least one component (I) with at least one component (II), to give the mixture (I/II); (2) mixing at least one component (III) with at least one finely divided solid component (IV), to give the mixture (III/IV); and then either (3) dispersing and/or dissolving the mixture (I/II) in the mixture (III/IV) or

Abstract: The present invention relates to a process for producing single-coat or multicoat clearcoat finishes on primed or unprimed substrates by applying at least one powder coating dispersion, in particular a powder clearcoat slurry, to the substrate and then curing the resulting film(s) thermally and/or with actinic radiation, in which at least one polyvalent inorganic acid and/or oxalic acid are or is added to at least one powder coating dispersion, in particular to a powder clearcoat slurry.
