Patent number: 4873273Abstract: A thermosetting resin composition particularly suitable for surface coatings, including metals, paper and paperboard, and especially those papers subsequently converted into shaped paperboard products, e.g. paper plates and folded cartons, with a high gloss, water and oil resistant surface coating. The composition is suitable also as both an adhesive and coating in metallizing substrates by the transfer of metallic particles from a transfer agent to the substrate. When formulated without solvents or dispersants it is suitable for use as a casting composition or as a molding material. The composition comprises a polymer or copolymer containing carboxylic acid groups; an epoxy compound containing an average of more than one epoxide group per molecule; an ammonium or phosphonium base or salt thereof; and a monomeric carboxylic acid or inorganic acid which extends the useful working life of the composition and imparts a superior glass to the surface of the finished product.Type: GrantFiled: June 7, 1988Date of Patent: October 10, 1989Assignee: James River-Norwalk, Inc.Inventors: John L.

Patent number: 4857566Abstract: This invention relates to a curable latex composition, films and foams produced therefrom and method for preparing said curable latex composition. The composition comprises a carboxylated latex, an epoxy resin emulsion containing an organo-soluble or organo-miscible catalyst and a water-soluble catalytic curing agent. The carboxylated latex comprises a copolymer of from 0 to 75 percent by weight of a vinyl aromatic monomer, from 0 to 85 percent by weight of a diene monomer and from 0.5 to 25 percent by weight of an ethylentically unsaturated carboxylic acid monomer, all weight percentages based on the total weight of the copolymer. The latex is produced by emulsion polymerization of one or more monomers in an aqueous environment. The various components of the curable latex composition may be maintained separately until shortly before use because of their ambient temperature curing properties. In some instances two or more components which do not react with each other can be premixed.Type: GrantFiled: December 28, 1987Date of Patent: August 15, 1989Assignee: The Dow Chemical CompanyInventor: Alois Helbling
