    Abstract: Disclosed is a composite coating, comprising a substrate; one or more primer coating layers disposed on said substrate; and at least one topcoat layer disposed on the outermost primer coating layer, wherein said outermost primer coating layer is obtained by reaction of a primer composition comprising an acrylic or novolac resin having primary carbamate functionality and an aminoplast resin.
    Also claimed is a coating composition comprising a carbamate functional resin and an aminoplast corsslinker.

    Abstract: Cathodic electrocoat compositions containing self-crosslinking polymers are described. The polymers of the invention are formed from an epoxide-functional prepolymer having polyepoxide and extender segments. Each extender segment has at least one pendant hydroxyalkyl carbamate group. The prepolymer is reacted with an amine compound having at least one blocked primary amine group and at least one epoxide-reactive group. The primary amine group is unblocked and the resultant polymer is dispersed in water with the aid of a neutralizing acid.

    Abstract: An electrodeposition process using an aqueous coating composition comprising a carbamate-functional crosslinking agent and at least one principal resin is described. The carbamate-functional crosslinker is formed by first reacting a polyamine having at least two primary amine groups and at least one secondary amine group with a cyclic carbonate, and then reacting the product of the first reaction with a polyepoxide compound.
