The metal organosilicate polymer particulate materials are obtainable by contacting a metal salt with a silicon-containing compound having an organic substituent in an organic solvent, wherein either the silicon-containing compound contains a basic group and/or the reaction is conducted in the presence of a base, wherein the metal is selected from one or more of aluminium, magnesium strontium, calcium or zinc and the silicon-containing compound comprises hydrolyzable and non-hydrolyzable substituents such as to form a metal organosilicate polymer particulate material therefrom. The described inkjet receiver is useful for forming images by inkjet printing having excellent colour fastness over time. | 01-07-2010 |
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 |
20100075042 | COMPOSITE MATERIALS FROM CHARGED OR FUNCTIONALIZED LATEXES FOR INKJET APPLICATIONS - An inkjet receiver comprising a support and one or more layers coated on the support, at least one of which comprises a particulate material and a binder, the particulate material comprising composite particles having an inner portion and an outer portion or core-shell arrangement, wherein the inner portion comprises a negatively-charged, positively-charged or functionalized latex, and the outer portion comprises an inorganic material having enhanced keeping properties and reduced ozone-induced dye fade. | 03-25-2010 |

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 |

20140045699 | STIMULUS-RESPONSIVE POLYMERIC PARTICLE FORMULATIONS - A stimulus-responsive formulation of stimulus-responsive polymer particles in aqueous composition has a rheology-stimulus profile (e.g. rheology-temperature) whereby it exhibits certain rheological behaviours over a range of temperatures, which is controllable by copolymerising a stimulus-responsive polymer-forming monomer, such as N-isopropylacrylamide, with a certain proportion of second monomer having weak acid functionality (such as acrylic acid) to form the stimulus-responsive microgel particles of the formulation and by addition of a base to the formulation to neutralise a portion but not all of the weak acid functionality. Thus a stimulus-responsive formulation may be controlled to exhibit gel-to-liquid-to-gel like behaviour with increasing temperature. | 02-13-2014 |
