    Abstract: Film-forming compositions which are substantially free of organic solvent and capable of forming a generally continuous film at ambient temperature are provided. The film-forming composition includes at least one thermosettable aqueous dispersion of polymeric microparticles having functionality adapted to react with a crosslinking agent. The polymeric microparticles are prepared by mixing under high shear conditions (1) at least one hydrophobic polymer having reactive functional groups; and (2) at least one hydrophobic crosslinking agent containing functional groups which are reactive with the functional groups of the polymer. Further provided is a multi-component composite coating composition which includes a pigmented base coat and a transparent topcoat of the substantially organic solvent-free film-forming composition described above. Substrates coated with the same are also provided. Additionally, a method for preparing the aqueous dispersion of polymeric microparticles is provided. The substantially organic solvent-free film-forming compositions of the invention are storage stable at room temperature and provide coatings with excellent appearance and performance properties such as adhesion and scratch resistance. The film-forming compositions are suitable for wet-on-wet application over a base coat with little or no mud-cracking.

    Abstract: A thermally curing powder coating composition comprising a mixture of resins wherein

    at least one resin has a hydroxy number of less than 75 mg KOH/g,
    at least one resin has a hydroxy number of at least 75 mg KOH/g, and a curing agent for the resins.

    The powder coating composition is suited in particular for the decoration of substrates by transfer printing of an image. Very good results are found if the powder coating is used for the decoration of ceramic or glass substrates.

    Abstract: A method for reducing the amount of microfoam in a spray-applied clear waterborne composition is provided, the clear waterborne composition including an emulsion-polymerized addition polymer bearing at least one first reactive group and a reactive modifier bearing one second reactive group and a water-soluble group, the second reactive group being reactive with the first reactive group; applying the composition to a substrate using a spray method; and drying the composition. A reduced amount of microfoam improves the clarity of a film of the composition. Also provided are monofunctional carbodiimide reactive modifiers and substrates bearing the spray-applied clear compositions.
