Patent number: 4810758Abstract: A resinous composition for coating use which is excellent in weather resistance and in low temperature curing properties, comprising a resin having resinous acid value based on carboxyl groups derived from its constituting tetrachlorophthalic acid of 2 to 8, a resinous acid value based on sulfonic acid groups derived from its constituting sulfophthalic acid of 0.5 to 5, and a functional group capable of reacting with a crosslinking agent to be compounded with the resin. The present resin is useful, in the combination form with a crosslinking agent, as a resinous vehicle of a coating composition which is excellent in curing properties, weather resistance, pigment dispersibility and storage stability and is specifically useful as an intermediate or top coat paint for automobile bodies or the like.Type: GrantFiled: March 12, 1987Date of Patent: March 7, 1989Assignee: Nippon Paint, Co., Ltd.Inventors: Hisaki Tanabe, Ryozo Takagawa, Hirotoshi Umemoto

Patent number: 4791179Abstract: A solvent-based thermosetting coating composition comprising a hydroxy functional epoxy-polyester graft copolymer and polyfunctional, hydroxy-reactive crosslinking agent. The coating composition may be formulated as a hot sprayable, high solids coating composition suitable for use as a chip resistant automotive vehicle primer adapted for use on body panel areas subject to chipping by stones, gravel and other road debris. The composition may also be formulated as a high solids composition sprayable with conventional spraying equipment. Hydroxy-functional epoxy-polyester graft copolymer is prepared by polymerization of lactone monomers in the presence of hydroxy functional epoxy ester resin precursor. The precursor is the reaction product of modified diepoxide and hydroxy functional secondary amine in about a 1:1 equivalent ratio.Type: GrantFiled: September 3, 1987Date of Patent: December 13, 1988Assignee: E. I. Du Pont de Nemours and CompanyInventors: Andrew H. Dervan, Panagiotis I. Kordomenos

Patent number: 4789707Abstract: There is disclosed a coating resin composition which contains as a crosslinking agent a melamine-formaldehyde resin which permits a paint to cure at low temperatures, permits a paint to form a coating film flexible enough for the fabrication of the coated substrate, gives off only a small amount of formaldehyde at the time of paint application, and makes it possible to increase the solids content in a paint. The melamine-formaldehyde resin is a mixed alkyl etherified methylol melamine resin, and the other composition-constituting component is an alkyd resin, polyester resin, or vinyl copolymer.Type: GrantFiled: March 2, 1987Date of Patent: December 6, 1988Assignees: Mitsui-Cyanamid Ltd., Nippon Paint Co., Ltd.Inventors: Tsutomu Nishimura, Yasuo Saito, Kenji Shindo, Kazutoshi Abe

Patent number: 4783497Abstract: Coating compositions suitable for use as coatings or inks for metallic foils, such as aluminum foil, as well as for use on other materials, such as papers and plastics resin films, are disclosed. These compositions comprise a water dispersable polyester resin, an alkylated amino resin and water. They may optionally include a pigment and other optional modifying ingredients. These compositions, being water-based, provide improved environmental compatibility and may be dried under relatively low temperatures without objectional ammonia residue odor.Type: GrantFiled: December 16, 1985Date of Patent: November 8, 1988Assignee: Reynolds Metals CompanyInventor: Gerald L. Thompson
