US Patent:

6354693, Mar 12, 2002
Filed:

Sep 11, 2000
Appl. No.:

09/659666
Inventors:

Steven D Looman - Corvallis OR
Mark H. Kowalski - Westford MA
George C Ross - Philomath OR
Michel A. Riou - Milwaukie OR
Paul David Gast - Camas WA
Brooke E Smith - Brush Prairie WA
Keshava A Prasad - San Marcos CA
Robert B McMaster - Vancouver WA
Assignee:

Hewlett-Packard Company - Palo Alto CA
International Classification:

B41J 221
US Classification:

347 43
Abstract:

One or more reactive color inks are printed under and over black text and graphics areas. That is to say, one or more reactive color inks are first printed in a selected area in which black text and/or graphics are to be printed, then the black text and/or graphics are printed, and finally one or more reactive color inks are then printed over the black text and/or graphics. The use of under- and over-printing of black text and/or graphics by reactive color inks improves several important characteristics of inkjet printing. Specifically, the following improvements are obtained: dry-time, finger smudge, media independence/print quality, waterfastness, strikethrough, less noticeable missing/misdirected nozzles, and no dedicated pens are required. Alternatively, either underprinting alone or overprinting alone may be used.

Abstract:

Disclosed is an ink composition suitable for ink jet printing comprising a luminescent compound, a solvent, and an energy active compound, and optionally a non-luminescent colorant. The energy active compound, when exposed to energy, generates one or more active species that can react with the luminescent compound to alter one or more of the characteristics of the luminescent compound. The luminescent compound can be colored or colorless. Also disclosed is a method for marking substrates comprising providing a mark comprising a luminescent compound and an energy active compound. Further disclosed is a jet ink composition suitable for printing on substrates authentication or security marks which can be rendered unreadable. The luminescence of the mark is quenched and the visible color is changed when irradiated with a light.

US Patent:

7297201, Nov 20, 2007
Filed:

Jan 6, 2005
Appl. No.:

11/030504
Inventors:

Steven D. Looman - Holland MI, US
John P. Folkers - Palatine IL, US
Assignee:

Videojet Technologies Inc. - Wood Dale IL
International Classification:

C09D 11/02
US Classification:

106 3158, 106 3128, 106 3186
Abstract:

Disclosed is an ink jet ink composition that forms indelible images on porous or semiporous substrates. The ink composition comprises a liquid carrier, a first colorant that is soluble in the carrier but insoluble or substantially insoluble in water, and a second colorant composition comprising a pigment, the second colorant composition being dispersible in the carrier. The second colorant composition is insoluble or substantially insoluble in the carrier. The images are difficult or impossible to remove or wash out by the use of aqueous and/or nonaqueous liquids.

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:

B05D 5/04
US Classification:

4273761, 4274071, 4274192
Abstract:

The present invention is drawn to a media sheet, comprising a substrate and a porous ink-receiving layer deposited on the substrate. The porous ink-receiving layer can comprise inorganic metal or semi-metal oxide particulates bound by a polymeric binder, and the porous ink-receiving layer can further include an effective amount of a sulfur-containing compound that interacts with ozone upon exposure thereto.

Filed:

Jun 1, 1995
Appl. No.:

8/458080
Inventors:

Desaraju V. Varaprasad - Holland MI
Steven D. Looman - Salt Lake City UT
Mingtang Zhao - Holland MI
Hamid R. Habibi - Holland MI
Niall R. Lynam - Holland MI
Assignee:

Donnelly Corporation - Holland MI
International Classification:

G02F 100
US Classification:

252583
Abstract:

The present invention relates to electrochromic solutions and devices manufactured therefrom. More precisely, the invention relates to electrochemichromic solutions, and those devices manufactured with the same, that demonstrate superior responsiveness to those solutions known heretofore when an applied potential is introduced thereto. That is, the responsiveness observed in terms of solution coloring is of a greater rapidity, intensity and uniformity than those electrochemichromic solutions of the prior art. Preparation of these solutions involve the novel process of pre-treating at least one of the electrochemichromic compounds with a redox agent prior to placing it in contact with the other electrochemichromic compound. Moreover, the present invention relates to methods of preparing such novel solutions and processes for using these solutions to provide devices that exhibit and benefit from the aforementioned superior characteristics.
