Curable film-forming compositions containing hydroxyl functional acrylic polymers and bisurea compounds and multilayer composite coatings

A curable film-forming composition comprising:

• (a) an acrylic polyol prepared from a monomer mixture comprising a hydroxyl functional monomer, wherein the hydroxyl functional monomer comprises a hydroxyalkyl group with an alkyl chain of at least four carbon atoms and wherein the acrylic polyol demonstrates a glass transition temperature less than 15° C.;
• (b) a rheology modifier comprising:
• (1) a non-aqueous dispersion of an internally crosslinked organic polymer;
• and
• (2) a reaction product of an amine and an isocyanate;
• and
• (c) a curing agent comprising functional groups that are reactive with hydroxyl functional group;
• wherein the reaction product (2) is dispersed in a second acrylic polyol prepared from a monomer mixture comprising:
• (i) a beta-hydroxy ester functional monomer prepared from an ethylenically unsaturated acid functional monomer and an epoxy compound containing at least 5 carbon atoms;
• (ii) hydroxyethyl methacrylate;
• (iii) styrene;
• (iv) 2-ethylhexyl acrylate.
