Abstract:
The present invention provides multilayer coated substrates, prepared using primer and/or sealer compositions comprising waterborne curable film-forming compositions, in turn comprising: a) an aqueous dispersion of a pigment and i) polymeric urethane-shell particles having a care-shell morphology and having hydroxyl functional groups, wherein the core is prepared from a monomer mixture comprising hydrophobic, ethylenically unsaturated monomers and the shell comprises a polyurethane or polyurethane-urea polymer; or ii) polymeric acrylic-shell particles having a core-shell morphology and having hydroxyl functional groups, wherein the core is prepared from a monomer mixture comprising hydrophobic, ethylenically unsaturated monomers and the shell is prepared from a monomer mixture comprising hydrophilic, ethylenically unsaturated monomers; b) a polyisocyanate crosslinking agent; and optionally c) a hydroxyl functional, water dispersible acrylic polymer.
