Patents by Inventor Anna M. Budde

Anna M. Budde has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Coating composition for coatings resistant to environmental etch
    Patent number: 5916986
    Abstract: A sterically-hindered monomer is used to make a polymer which in turn is useful in coating compositions. The resulting residue of the sterically-hindered monomer is present in the polymer, as well as in a cured coating (preferably an automotive coating) produced using a coating composition having the polymer therein. The presence of the residue of the sterically-hindered monomer imparts in the cured coating a resistance to environmental etching.
    Type: Grant
    Filed: November 20, 1996
    Date of Patent: June 29, 1999
    Assignee: BASF Corporation
    Inventors: Anna M. Budde, James A. Laugal, Walter H. Ohrbom, Marvin L. Green, Mark R. Montagne
  • Substrate having coating resistant to environmental etch, coating composition therefor, process for making the coating composition, and process of coating a substrate with the composition

  • Post-extended anionic acrylic dispersion
    Patent number: 5629374
    Abstract: The present invention is directed to an aqueous anionic acrylic dispersion produced bya) dispersing an acrylic resin, having functional groups selected from the group consisting of carboxylic acid groups, carboxylic anhydride groups or mixtures thereof in water in the presence of a tertiary amine andb) reacting the carboxylic acid groups on the acrylic resin with an organic compound having at least two oxirane groups,a basecoat and a rheology control agent comprising said aqueous anionic acrylic dispersion, a method of coating a substrate with said dispersion and the coated substrate.
    Type: Grant
    Filed: May 3, 1995
    Date of Patent: May 13, 1997
    Assignee: BASF Corporation
    Inventors: Anna M. Budde, Timothy D. Salatin
  • Cellulose esters moidified with anhydrides of dicarboxylic acids and their use in waterborne basecoats
    Patent number: 5384163
    Abstract: Novel coating compositions containing modified cellulose esters are disclosed. The modified cellulose esters contain acid functionality, permitting their dispersion in aqueous systems. The modified cellulose esters are particularly useful as rheology control agents in coatings which are applied as waterborne dispersions. The novel coating compositions are used to produce coated substrates with desirable appearance characteristics.
    Type: Grant

  • Post-extended anionic polyurethane dispersion
    Patent number: 5236995
    Abstract: The present invention is directed to an aqueous anionic polyurethane dispersion, obtainable bya) dispersing a polyurethane resin, having carboxylic acid groups, in water in the presence of a tertiary amine andb) reacting the carboxylic acid groups on the polyurethane resin with an organic compound having at least two oxirane groups,a basecoat containing said dispersions,a method of coating a substrate with said basecoat and a coated substrate.
