Patent number: 4335829Abstract: An aqueous resinous dispersion and a method of coating employing the aqueous resinous dispersion are disclosed. The aqueous resinous dispersions are solubilized with base and comprise an acrylic polymer containing N-ethoxymethylacrylamide or methacrylamide moieties and an epoxy resin. The dispersion is useful for coating metal containers particularly as a coating for the interior of containers which are used for alcoholic beverages, for example, beer cans.Type: GrantFiled: November 29, 1978Date of Patent: June 22, 1982Assignee: PPG Industries, Inc.Inventors: Roger M. Christenson, Rudolf Maska, Rostyslaw Dowbenko, Thomas R. Hockswender

Patent number: 4328144Abstract: Room temperature curable latices can be produced by copolymerizing ketimine derivative ethylenically unsaturated monomers with conventional ethylenically unsaturated monomers in an emulsion process at a controlled pH greater than about 7.2 to produce a coagulum-free latex containing blocked amine (--NH.sub.2) groups. In use, the pH of the latex can be adjusted to acidic below 7 to generate unblocked reactive amino groups which can be cured or cross-linked at about room temperature with water-dispersed polymers such as epoxy, double bond or isothiocyanate containing polymers.Type: GrantFiled: March 17, 1980Date of Patent: May 4, 1982Assignee: SCM CorporationInventor: James T. K. Woo

Patent number: RE31022Abstract: Resinous compositions which are the Michael adducts of primary and/or secondary amines and polymers containing alpha, beta-ethylenically unsaturated moieties in conjugation with carbonyl moieties are disclosed. The compositions are depositable on substrates to form films. The films are amenable to oxidative and aminoplast cures and cure with light color. The compositions are desirable for use in cationic electrodeposition.Type: GrantFiled: March 26, 1981Date of Patent: August 31, 1982Assignee: PPG Industries, Inc.Inventors: Stephen L.
