Abstract

Disclosed are coating compositions that can be one-component, ambient curable, and waterborne. The coating compositions include a polymer that is the reaction product of a polycarbodiimide and a ketocarboxylic acid. Also disclosed are substrates coated with a coating deposited from such compositions, as well as methods for depositing a coating on a substrate, and coated substrates.
