Solvent-free film-forming compositions, coated substrates and method related thereto

A curable composition comprising:

• an aqueous dispersion of polymeric microparticles, said microparticles having a functionality adapted to react with a crosslinking agent and being prepared in a medium substantially free of organic solvent from a mixture of the following components:
• (1) at least one reaction product of polymerizable, ethylenically unsaturated monomers;
• (2) at least one reactive functional group-containing organopolysiloxane having the following structure (II) or (III):
• wherein m has a value of at least 1;
• each of (n+m) and (n+m′) ranges from 2 to 3;
• R is selected from the group consisting of H, OH and monovalent hydrocarbon groups bonded to the silicon atoms;
• and Ra comprises the following structure (IV):
• R1—X (IV)
• wherein R1 is alkylene, oxyalkylene or alkylene aryl;
• and X comprises a functional group-containing moiety;
• and
• (3) at least one hydrophobic crosslinking agent having reactive functional groups, said hydrophobic crosslinking agent comprising at least one compound selected from blocked isocyanates, aminoplast resins, and mixtures thereof, wherein components (1) and/or (2) contain functional groups reactive with the functional groups of (3).
