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.

An anionic electrocoating composition is provided including an electrodepositable .beta.-hydroxyalkylamide curing agent and an electrodepositable polymer capable of crosslinking with the curing agent. This curing agent includes an organic radical that (a) contains from 8 to 60 carbon atoms; (b) is derived from a substituted or unsubstituted aliphatic, alicyclic or aromatic hydrocarbon radical; and (c) is bonded to n .beta.-hydroxyalkylamide groups, wherein n is an integer from 1 to 4, to form ##STR1## where R.sup.1 can be H or a substituted or unsubstituted aliphatic, alicyclic or aromatic group containing up to 6 carbon atoms;

Anionic electrocoating compositions containing hydroxyalkylamide curing

The disclosure is directed to a compound which is a reaction product of at least one phosphonic acid group of an alpha-aminomethylene phosphonic acid containing at least one group corresponding to the formula, ##STR1## with an epoxy group of a compound containing at least one epoxy group. The disclosure is also directed to waterborne coating compositions, organic solvent-borne coating compositions, and powder coating compositions containing the aforesaid reaction product.

Reaction products of alpha-aminomethylene phosphonic acids and epoxy

The thermosetting powder coating composition which has good stability and good physical properties, such as appearance, flexibility, hardness, solvent resistance and corrosion resistance, is disclosed. The composition comprises a co-reactable particulate mixture of a carboxylic acid group-containing polymer, a polyepoxide, and a beta-hydroxylalkylamide.

A method of molding involves the formulation of molding compositions with polymerizable ethylenically unsaturated urea-urethane polymer dispersions.

Method of molding

A coated article has a coating which is an at least partially cured coating composition prepared from a polyurea-polyurethane acrylate dispersion.

Coated article

A method of in-mold coating a molded article involve the formulation of in-mold coating compositions and molding compositions with polymerizable ethylenically unsaturated urea-urethane polymer dispersions.

Method of in-mold coating

Polymerizable ethylenically unsaturated urea-urethane polymer dispersions are prepared. In preparing the dispersions a polyisocyanate, at least a portion of which is diisocyanate, is contacted with a polyfunctional amine containing primary and/or secondary amino groups in the presence of:
