Disclosed are thermosetting compositions which are comprised of a resinous phase dispersed in an aqueous medium, the resinous phase comprising (a) an ungelled active hydrogen group-containing polymer which contains onium salt groups, the polymer having been prepared by atom transfer radical polymerization in the presence of an initiator having at least one radically transferable group, and (b) a curing agent having at least two functional groups which are reactive with the active hydrogen groups of (a). The active hydrogen group-containing polymers of the thermosetting compositions, which are prepared by atom transfer radical polymerization, have narrow molecular weight distributions and well-defined, specifically tailored polymer architecture which can provide enhanced crosslink density and dispersibility of the thermosetting compositions. Also disclosed is a method of electrocoating a conductive substrate using the thermosetting compositions of the invention, and a substrate coated by this method.

The present invention is directed to an electrodepositable composition of a resinous phase dispersed in an aqueous medium. The resinous phase includes an ionic polyester polymer prepared from a) an aromatic and/or cycloaliphatic carboxylic acid compound having at least two aromatic and/or secondary aliphatic carboxyl groups, b) a branched aliphatic, cycloaliphatic or araliphatic compound containing at least two aliphatic hydroxyl groups, the aliphatic hydroxyl groups being either secondary or tertiary hydroxyl groups or primary hydroxyl groups attached to a carbon adjacent to a tertiary or quaternary carbon, c) a compound including an ionic salt group or a group which is converted to an ionic salt group, and d) optionally, at least one hydroxyl substituted carboxylic compound comprising at least one tertiary aliphatic carboxyl group and at least two aliphatic hydroxyl groups. The present invention also includes a method for electrocoating a conductive substrate with the described electrodepositable composition. Lastly, the present invention is directed to a conductive substrate coated according to the described method.

Processes for forming a coating on electroconductive flat blanks having two major surfaces and sheared edges are provided. Also provided is a process for forming a multi-composite coating on a pre-sheared, electroconductive, flat blank having two major surfaces and sheared edges. Methods for forming and coating metal blanks are also provided. The present invention further provides a pre-sheared, flat electroconductive blank having two major surfaces and coated with a multi-layer composite coating composition on one major surface. The present invention also provides a method for coating a continuous metal strip, optionally, thereafter forming a coated blank therefrom, and, optionally, applying a second coating to the blank.
