US Patent:
6660072, Dec 9, 2003
Filed:
Dec 21, 2001
Appl. No.:
10/028197
Inventors:
Amiya K Chatterjee - San Diego CA
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
C09D 1102
US Classification:
106 3158, 106 3143, 106 3175, 106 3186
Abstract:
Improved inkjet ink compositions have a sufficient amount of an acetylenic alcohol incorporated therein to reduce the corrosiveness of the ink without adversely affecting the printing characteristics of the ink composition. The inkjet ink compositions of the invention include a carrier, a colorant that is soluble or dispersable in said carrier, and a sufficient quantity of at least one acetylenic alcohol to reduce the corrosiveness of said ink composition to metal placed in contact with said ink composition. The inkjet ink compositions may also include at least one acetylenic alcohol that contains a terminal acetylene and an -hydroxy group. A method for reducing corrosiveness of an inkjet ink composition includes adding to said inkjet ink composition a sufficient quantity of at least one acetylenic alcohol to reduce the corrosiveness of said ink composition to metal placed in contact with said ink composition.

Branched Alcohols And Diols For Increased Dot Size And Reliability

View page
US Patent:
6808556, Oct 26, 2004
Filed:
Oct 29, 2001
Appl. No.:
10/000043
Inventors:
Amiya K. Chatterjee - San Diego CA
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
C09D 1102
US Classification:
106 3158, 106 3186
Abstract:
The inks provide excellent ink-jet prints having excellent imaging onto glossy inkjet media with increased dot size leading to improved dot visibility and banding robustness of the image. The aqueous inks each comprise from about 0. 1 to about 20 wt % of at least one colorant (CMYK) with the black ink comprising from about 0. 5 to about 20 wt % of at least one colorant; from about 7 to about 20 wt % of at least one 1,2-diol, from about 0. 5% to about 2 wt % of a mono- or di-hydric alcohol; 0 to about 1. 5 wt % of at least one component independently selected from the group consisting of buffers, biocides, and metal chelators; and the balance water. The formulations are substantially free of surfactants and other solvents.

Ink-Jet Inks For Improved Image Quality And Reliability

US Patent:
6818048, Nov 16, 2004
Filed:
Oct 30, 2001
Appl. No.:
10/001637
Inventors:
Keshava A. Prasad - San Marcos CA
Amiya K. Chatterjee - San Diego CA
John M. Gardner - San Diego CA
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
C09D 1102
US Classification:
106 3158
Abstract:
The present invention provides ink-jet inks for ink-jet printing, comprising from 0. 1% to 5% by weight of at least one dye; from 8% to 20% by weight of a diol selected from the group consisting of 1,2-pentanediol, 1,2-hexanediol, and combinations thereof; from 0. 1% to 5% by weight of an aliphatic alcohol or aliphatic alcohol mixture; and from 0. 1% to 1. 5% by weight of at least one component independently selected from the group consisting of buffers, biocides, and metal chelators, with the proviso that no surfactant is present in the ink-jet ink composition. The ink-jet inks formulated according to the present invention provide good dot size, color-to-color bleed alleviation, improved coalescence, less chia, and improved print head materials compatibility.

Auxiliary Fluids Which Give Improved Print Permanence

US Patent:
6866381, Mar 15, 2005
Filed:
Sep 30, 2002
Appl. No.:
10/261721
Inventors:
Melissa D. Lee - Escondido CA, US
Amiya K Chatterjee - San Diego CA, US
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
B41J002/01
US Classification:
347101, 347105, 347100
Abstract:
Smear resistant ink jet ink images and methods for making such are disclosed and described. Generally, a smear resistant ink jet ink image includes an ink jet ink image upon a print substrate, and a water insoluble protective film having contact with the ink jet ink in the image. In one aspect, the film may include a combination of water soluble film forming polymers that become water insoluble upon interaction with one another. In another aspect, the water soluble film forming polymers may be interacted at the print substrate to form the water insoluble film.
