20080317960 | Dispersant for Reducing Viscosity of Solids - The invention provides a dispersant for an aqueous dispersion of negatively charged or chargeable solid particulates which comprises a compound having an anchoring moiety linked to a polymeric hydrophilic moiety, the anchoring moiety containing at least one basic group and having an overall basicity and the polymeric moiety having a lower affinity for the particulate surface than the anchoring moiety. The invention also provides a coating composition containing the dispersant, an inkjet recording element containing the dispersant and methods of coating or reducing viscosity using the dispersant. | 12-25-2008 |
20090322811 | INKJET PRINTING SYSTEM - An inkjet printing system comprising a plurality of static inkjet printing units each comprising at least one inkjet printing head; an ink-receiving element comprising a poorly-absorbing or impermeable substrate; an aqueous inkjet composition which comprises a polymeric compound comprising discrete particles responsive to an external stimulus, and a functional material, which may be incorporated as part of the polymeric particles, the composition having a first rheological state and a different second rheological state in response to a stimulated change in conditions, the first state being associated with a first lower viscosity of the composition, wherein the particles have a first lower volume, and the second state being associated with a second higher viscosity of the composition, wherein the particles have a second higher volume, and of drying the aqueous ink composition only positioned downstream of the plurality of the printing units. | 12-31-2009 |
20100026773 | INKJET RECORDING MEDIA WITH CATIONICALLY-MODIFIED CLAY PARTICLES - An inkjet printing system, comprises an inkjet printer, an ink composition, and an inkjet recording media comprising a support, and coated on the support in order from the support, a porous base layer, a porous intermediate layer, and a porous uppermost layer, each with particular limitations. The inkjet recording media and printer system is manufacturable using low-cost materials in an efficient process requiring only a single coating and drying step and that gives images with excellent gloss, color density and image quality. | 02-04-2010 |
20100028571 | INKJET RECORDING MEDIA WITH CATIONICALLY-MODIFIED CLAY PARTICLES - An inkjet printing system, comprises an inkjet printer, an ink composition, and an inkjet recording media comprising a support, and coated on the support in order from the support, a porous base layer and a porous uppermost layer, each with particular limitations The inkjet recording media and printer system is manufacturable using low-cost materials in an efficient process requiring only a single coating and drying step and that gives images with excellent gloss, color density, and image quality. | 02-04-2010 |
20100068387 | INK FOR PRINTING ON LOW ENERGY SUBSTRATES - The invention provides an aqueous inkjet ink composition comprises a polymeric compound comprising discrete particles responsive to an external stimulus, and a functional material, wherein the functional material may be incorporated as part of the polymeric particles, the particles causing the composition to have a first rheological state and a different second rheological state in response to a stimulated change in conditions, the first rheological state being associated with a first lower viscosity of the composition, wherein the particles have a first lower volume, enabling the composition to pass through an inkjet printhead orifice and the second rheological state being associated with a second higher viscosity of the composition, wherein the particles have a second higher volume, enabling immobilisation of droplets of the composition on a substrate. The inkjet composition is particularly useful in a continuous inkjet printing system for printing onto a wide range of surfaces including impermeable surfaces. | 03-18-2010 |
20100238232 | CONTINUOUS INK JET PRINTING OF ENCAPSULATED DROPLETS - A method for creating composite droplets for use in an ink jet system includes a first fluid ( | 09-23-2010 |
20110041715 | FLEXOGRAPHIC PRINTING INKS - A flexographic printing composition which comprises a carrier-swellable particle composition, such as a microgel particle composition, has improved printing performance and printing resolution, especially where the flexographic printing composition is an aqueous printing composition and the carrier is water. The composition is particularly beneficial for flexographic printing of such an aqueous printing ink onto low-energy surface substrates or impermeable substrates, in which the ink has improved adhesion, even in the absence of corona discharge treatment. The use of surfactant in an amount of at least 0.5% by weight of the ink composition enhances printed density and/or reduces mottling in solid printed areas. | 02-24-2011 |
