Abstract
Curable film-forming compositions are provided. The compositions comprise (a) a curing agent comprising reactive functional groups; (b) a film-forming compound comprising functional groups reactive with the reactive functional groups in (a); and (c) a catalyst component added to the curable film-forming composition as a dispersion of micelles in a continuous phase. The catalyst component (c) comprises a catalyst compound contained within or encapsulated by a carrier, and the catalyst compound and carrier together form the micelles in the continuous phase. The carrier comprises block copolymers that comprise at least one hydrophobic block derived from hydrophobic monomers and at least one hydrophilic block derived from (1) hydrophilic monomers and/or (2) monomers containing groups that may be rendered hydrophilic after polymerization.
