Film-forming materials include resins having a covalently bonded phosphorous atom, the phosphorous atom having at least one covalently bonded oxygen atom. Film-forming resins containing phosphorous can include epoxy, acrylic, polyurethane, polycarbonate, polysiloxane, polyvinyl, polyether, aminoplast, and polyester resins. A process to produce a film-forming resin includes reacting various polymers to incorporate a pendent group comprising a covalently bonded phosphorous atom. Methods of making a coating composition including a film-forming material having a covalently bonded phosphorous atom, the phosphorous atom having at least one covalently bonded oxygen atom. Coating compositions can be used to coat a substrate, such as a metal substrate, by electrodeposition. Applied coatings containing the film-forming resins can be cured to form crosslinked films on substrates. |
