Method for producing a phosphorus-containing coating compositions and phosphorus-containing film-forming material

摘要

And a resin having a phosphorus atom covalently linked, film-forming material has an oxygen atom which is covalently bonded at least one phosphorus atom. Epoxy resins, acrylic resins, polyurethane resins, polycarbonate resins, polysiloxane resins, polyvinyl resins, polyether resins, aminoplast resins, and phosphorus-containing film-forming resin may comprise a polyester resin. By the reaction of various polymers, process for producing the film-forming resin comprises a step of incorporating a pendant group containing a phosphorus atom covalently bonded. A film-forming material having a phosphorus atom covalently linked, a method of the phosphorus atom to produce a coating composition comprising a film-forming material having an oxygen atom which is covalently bonded at least one. Can be used to coating compositions, coated by electrolytic deposition, the substrates such as metal substrates. It can be cured coatings painted containing film-forming resin to form a crosslinked film on the substrate.
