The present invention provides a multilayer coated substrate prepared using a primer and/or sealant composition comprising an aqueous curable film-forming composition comprising in order: a) an aqueous dispersion of: a pigment and i) Polymeric urethane-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 comprises polyurethane or Polyurethane-urea polymers; or ii) polymeric acrylic-shell particles having a core-shell morphology and having hydroxyl functionality, wherein the core is prepared from a monomer mixture comprising hydrophobic, ethylenically unsaturated monomers , and the shell is prepared from a monomer mixture comprising a hydrophilic, ethylenically unsaturated monomer; b) a polyisocyanate crosslinker; and optionally c) a hydroxyl-functional, water-dispersible acrylic polymer. |
