Abstract: Coating compositions having improved mar and scratch resistance are disclosed. The coatings generally comprise one or more polymers comprising a monomer formed between a particle having a functional group and a modifying group having ethylenic unsaturation. The improved resistance can be achieved without affecting the appearance or mechanical performance of the coatings. Methods for using the coatings, and the substrates coated therewith, are also disclosed, as are the monomers and polymers that comprise the coatings.

Abstract: Methods of preparing an organic sol of particles are provided. Steps include providing a suspension of particles in an aqueous medium; adding a first organic liquid compatible with the aqueous medium to form an admixture; reacting the particles with a first and a second modifying compound; adding a second organic liquid compatible with the liquid portion of the admixture wherein the second organic liquid is different from the first organic liquid; and maintaining the admixture at a temperature and pressure and for a time sufficient to substantially remove the water and the first organic liquid. Also provided are curable film-forming compositions containing sols of particles prepared by the methods of the present invention.
