The present invention is directed to a method for forming a composite coating on a substrate. The method comprises: Also provided are coated substrates prepared using the above method.

Method of forming multi-component composite coating compositions on substrates using compact processes

An aqueous dispersion comprising a reaction product of trimellitic anhydride and a polyol, wherein the molar ratio of trimellitic anhydride to polyol in the reaction product ranges from 1:2 to 1:4, and wherein the reaction product is further reacted with an anhydride to form another reaction product. A method of making a resin comprising the reaction product described above is also disclosed.

Aqueous dispersion comprising a branched triol having trimellitic anhydride and associated method

Aqueous resinous binders comprising graft copolymers, water-dilutable urethane polyols and epoxy-phosphorus acid reaction products are disclosed. The binders are useful in primer formulations for automotive applications.
