A coating composition having excellent cure at ambient conditions and comprising (i) at least one imine, (ii) a polyisocyanate having an average of at least two isocyanate groups per molecule, (iii) at least one polyaspartic ester, and (iv) an isocyanate functional urethane; wherein the coating composition is substantially free of hydroxy functionality. Coatings produced from the coating composition of this invention exhibit superior performance on flexible substrates.

Polyimine/polyisocyanate coating composition

An unsaturated acid-functional monomer having the structure: ##STR1## wherein R is hydrogen or methyl and polymers prepared using the monomer are disclosed.

Dicarboxylic acid-functional monomers and polymers prepared from same

Anhydride-functional polymerizable monomers having the structure: ##STR1## and polymers and reactive compositions prepared from these monomers are disclosed. The reactive compositions are especially useful in primer and clearcoat/basecoat applications.

Anhydrid-functional monomers and polymers and reactive compositions

Anhydride-functional monomers and polymers and reactive compositions

A coating composition having extended pot-life and excellent cure at ambient conditions. The coating composition comprises (i) at least one imine, (ii) a polyisocynate having an average of at least two isocyanate groups per molecule, (iii) at least one polyaspartic ester, and (iv) an anhydride functional polymer; wherein the coating composition is substantially free of hydroxy functionality.
