Sep 17, 2001

Appl. No.:

09/954467

Inventors:

John Alford - Goose Creek SC, US

Assignee:

Westvaco Corporation

International Classification:

C03C017/00
C09D005/00

US Classification:

523/160000, 523/161000

Abstract:

The present invention relates to aqueous, pigment-based ink compositions for use in ink jet printers. These compositions comprise a carrier medium, an insoluble pigment, and a polymer produced by reacting a mixture of styrene, acrylic acid, and butyl acrylate in a polymerization reaction. The ink compositions are characterized by their water resistance and accent marker resistance properties, while also achieving excellent print quality, jetting properties, storage stability, reliability, and dying times.

US Classification:

524/086000, 523/160000, 523/161000

Abstract:

The present invention relates to aqueous, pigment-based ink compositions for use in ink jet printers. These compositions comprise a carrier medium, an insoluble pigment, and a polymer produced by polymerizing at least one ethylenically-unsaturated monomer with at least one glycol ester monomer. The ink compositions are characterized by their water resistance and accent marker resistance properties, while also achieving excellent print quality, jetting properties, storage stability, reliability, and dying times.

Appl. No.:

8/046077

Inventors:

Eugene R. Fischer - James Island SC
John A. Alford - Goose Creek SC
Paul G. Boyd - Moncks Corner SC

Assignee:

Westvaco Corporation - New York NY

International Classification:

C23F 1104

US Classification:

422 12

Abstract:

A corrosion inhibitor with excellent film forming and film persistency characteristics may be produced by first reacting C. sub. 18 unsaturated fatty acids with maleic anhydride or fumaric acid to produce the fatty acid Diels-Alder adduct or the fatty acid-ene reaction product. This adduct or reaction product is further reacted in a condensation or hydrolysation reaction with a polyalcohol to form an acid-anhydride ester corrosion inhibitor. The ester may be reacted with amines, metal hydroxides, metal oxides, ammonia, and combinations thereof to neutralize the ester. Surfactants may be added to tailor the inhibitor formulation to meet the specific needs of the user (i. e. , the corrosion inhibitor may be formulated to produce an oil-soluble, highly water-dispersible corrosion inhibitor or an oil-dispersible, water-soluble corrosion inhibitor). Suitable carrier solvents may be employed where needed to effectively disperse the corrosion inhibitor formulation.

International Classification:

H01G 900

US Classification:

361502

Abstract:

The present invention relates to lignocellulosic-based carbon-containing double layer energy storage devices having improved electrical power densities. In particular, the invention provides a double layer energy storage cell comprising a pair of electrodes, at least one of which is a carbon paste electrode, a porous ionically conductive separator, and an ion insulating connector, the improvement wherein said carbon paste electrode includes an activated linocellulosic-based carbon having a pore volume of greater than about 0. 45 cc/g, a median pore width of 2. 0 to 50. 0 nm, a specific surface area of greater than about 500 m. sup. 2 /g, and a mesopore content, based on the total particle volume of the activated carbon, of greater than about 75%.
