摘要： Polymeric urethane dispersants with solubilizing polymer chains and with reactive carbon to carbon double bonds are described. The reactive double bonds facilitate molecular weight build-up of the dispersant on dispersed particles (enhancing colloidal stability) or enhance the ability of the dispersants to be crosslinked into a matrix material.

摘要： Methods and apparatus are provided for preventing clogging in impulse inkjet printers. It has been found in accordance with the invention that ink clogging during quiescent periods can be prevented by providing an ink that has the property of forming a barrier of higher viscosity ink where the ink contacts the ambient air. As a result, the viscous barrier shields the remaining ink from the effects of air exposure during the quiescent period. Thereafter, the barrier is removed by a series of sub-pulses that re-homogenize the viscosity barrier and clear the nozzle.

摘要： Described is the preparation of a composition suitable for inkjet printing, produced by blending a viscous printing composition suitable for application by an impact printing technique and a diluent. For hydrophilic viscous printing composition the diluent comprises: (i) water; (ii) a glycol; (iii) at least one surface tension modifier; (iv) optionally, ammonium hydroxide; and (v) optionally, one or more solvents. For lipophilic viscous printing composition the diluent comprises a surface tension modifier which is soluble in a fatty acid-based oil. Also described is a process for preparing the composition from a screen printing paste and a process for utilizing an ink jet to apply a viscous printing composition to a substrate.
