Abstract: Disclosed is a coating formed from a composition containing a film-forming resin and a plurality of particles dispersed in the resin. The average particle size of the particles is 0.1 to 50 microns, and the particles have a hardness sufficient to impart greater mar and/or scratch resistance to the coating as compared to a coating where no particles are present. Also, the difference between the refractive ranges from 1 to 1.5. A method for preparing a powder coating including the particles also is provided.

Abstract: A thermosetting composition that includes a co-reactable solid, particulate mixture of a film forming material having functional groups, a crosslinking agent having at least two functional groups that are reactive with the functional groups in the film forming material, and a monocarboxylic acid.

Abstract: A thermosetting composition that includes a co-reactable solid, particulate mixture of a film forming material having functional groups and a crosslinking agent having at least two functional groups that are reactive with the functional groups in the film forming material. The crosslinking agent includes a copolymer having at least 30 mol % of alternating structural units of a residue from a donor monomer and a residue from one or more acrylic acceptor monomers. The thermosetting composition may coat a substrate by coalescing the composition to form a continuous film and curing the composition. The thermosetting composition may be included as part of a multi-component composite coating composition that includes an optional primer coat, a base coat deposited from a pigmented film-forming composition, and a transparent top coat applied over the base coat, where either the base coat, the transparent top coat, or both, are deposited from the thermosetting composition.

The additives in the composition prevent thermal oxidation, minimizing visual effects (i.e., yellowing). A multi-component composite coating includes a base coat and a top coat which may be derived from the above curable film-forming composition.
