Definitions

  • the present invention relates to ink compositions having modified pigments with high or low levels of organic treatment.
  • the ink compositions exhibit improved intercolor bleed properties and are suitable in inkjet printing inks and in inks incorporating such modified pigments.
  • the pigment can be any pigment that can be modified with the attachment of at least one organic group. Examples include, but are not limited to, a carbon product, a colored pigment other than a carbon product, a multi-phase aggregate comprising at least one carbon phase and at least one silicon-containing species phase, a multi-phase aggregate containing at least one carbon phase and at least one metal- containing species phase, a partially silica coated carbon black, or mixtures thereof.
  • Carbon, as used herein, may be of the crystalline or amorphous type. Examples include, but are not limited to, graphite, carbon black, carbon fiber, vitreous carbon, activated charcoal, or activated carbon. Finely divided forms of the above are preferred.
  • black pigments include various carbon blacks (Pigment 5 Black 7) such as channel blacks, furnace blacks and lamp blacks, and include, for example, carbon blacks sold under the Regal®, Black Pearls®, Elftex®, Monarch®, Mogul®, and Vulcan® trademarks available from Cabot Corporation (such as Black Pearls® 2000, Black Pearls® 1400, Black Pearls® 1300, Black Pearls® 1100, Black Pearls® 1000, Black Pearls® 900, Black Pearls® 880, Black Pearls® 800, Black o Pearls® 700, Black Pearls® L, Elftex® 8, Monarch® 1400, Monarch® 1300, Monarch® 1100, Monarch® 1000, Monarch® 900, Monarch® 880, Monarch® 800, Monarch® 700, Mogul® L, Regal® 330, Regal® 400, Vulcan® P).
  • carbon blacks sold under the Regal®, Black Pearls®, Elftex®, Monarch®, Mogul®, and Vulcan® trademarks available from
  • the organic group can also be an olefin group, a styrenic group, an acrylate group, an amide group, an ester group, or mixtures thereof.
  • the organic group can be a polymeric group, such as a polyolefm group, a polystyrenic group, a polyamide group, a polyester group, or mixtures thereof.
  • the organic group can also be an alkylene oxide.
  • the modified pigment may be prepared preferably by reacting a pigment, such as carbon black, with a diazonium salt in a liquid reaction medium to attach at least one organic group to the surface of the pigment.
  • the diazonium salt may contain the organic group to be attached to the pigment.
  • a diazonium salt is an organic compound having one or more diazonium groups.
  • Preferred reaction media include water, any medium containing water, and any medium containing alcohol. Water is the most preferred medium. Examples of modified carbon products, wherein the carbon is carbon black, and various preferred methods for their preparation are described in U.S. Patent No. 5,851,280 entitled "Reaction of Carbon Black with Diazonium Salts, Resulting Carbon Black," incorporated herein by reference in its entirety.
  • modified carbon products wherein the carbon is not carbon black
  • various preferred methods for their preparation are described in U.S. Patent No. 5,554,739, 5,837,045, WO 96/18696 and WO 96/18688, incorporated herein by reference in their entirety.
  • the pigments other than carbon products can be prepared in a similar manner.
  • the amount of organic group attached to the pigment is an important factor for purposes of the subsequent use of the modified pigment and such applications as inkjet ink compositions, coating formulations, and ink systems.
  • the treatment levels should be of a high level especially if excellent resistance to intercolor bleed is desired.

Abstract

L'invention concerne des compositions d'encre renfermant des pigments modifiés à niveaux de traitement élevés ou faibles. Les compositions d'encre comprenant des pigments modifiés à niveaux de traitement élevés renferment 1) au moins un vecteur liquide et 2) au moins un pigment modifié. Ces compositions sont caractérisées en ce que le pigment modifié renferme au moins un pigment auquel est attaché au moins un groupe organique substitué par un groupe anionique au moins, un groupe anionisable au moins, ou un mélange de ceux-ci, le groupe organique étant présent à un niveau de traitement compris entre 4,5 environ et 7,5 environ micromoles/m2 du pigment utilisé en fonction de la surface azotée du pigment. Les composition d'encre comprenant des pigments modifiés à niveaux de traitement faibles comprennent 1) au moins un vecteur liquide et 2) au moins un pigment modifié, le pigment modifié comprenant au moins un pigment auquel est attaché au moins un groupe organique substitué par au moins un groupe cationique, au moins un groupe cationisable, ou un mélange de ceux-ci, le groupe organique étant présent à un niveau de traitement compris entre 1 environ et 4 environ micromoles/m2 du pigment utilisé en fonction de la surface azotée du pigment. La présente invention concerne également des procédés permettant d'améliorer les propriétés de fondu des couleurs d'une encre, par utilisation des composants précités dans l'encre.
