Publication number: 20100068387Abstract: 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.Type: ApplicationFiled: December 19, 2007Publication date: March 18, 2010Inventors: Danuta Gibson, John M. Higgins, Stephanie V. Desrousseaux, Andrew M. Howe, Andrew Howe, Andrew Clarke, Christian V. Nicholas, John H. Hone

Publication number: 20100068476Abstract: A single phase aqueous curable composition suitable for thermal inkjet printing comprises a mixture of curable materials, water in amounts in the range 10 to 30% of the weight of the compositions, and one or more co-solvents for the curable materials. Because the water content is relatively low, a drying step is not required before curing, increasing printing speeds. The composition has good performance and has good adhesion to a wide range of substrates including non-porous and semi-porous materials as well as porous materials.Type: ApplicationFiled: November 2, 2007Publication date: March 18, 2010Inventors: Natasha Jeremic, Shaun Christopher Hazlewood
