摘要:
A phase change ink includes an ink vehicle that includes at least one curable carrier, at least one gellant, at least one wax and at least one alkoxysilane monomer. In a method of forming an image with the ink, the phase change ink is melted, then jetted onto an image receiving substrate, wherein the phase change ink forms a gel state, and exposed to ultraviolet light to cure the curable components of the phase change ink. The alkoxysilane participates in crosslinking to form silicon-oxygen-silicon bonds, thereby producing an ink with advantageous stability and high image quality.

This disclosure is generally directed to curable gel inks, such as radiation-curable phase-change inks, and their use in forming images, such as through inkjet printing. More specifically, this disclosure is directed to radiation-curable gel inks, such as ultraviolet-light-curable phase-change inks, that comprise a curable gellant and a curable solid.

Methods of controlling gloss of an image are disclosed. The methods may include forming an image over a substrate by applying an ink composition and optionally an overcoat composition at least partially over the substrate. The ink composition or overcoat composition may include at least one gellant, at least one curable monomer, optionally at least one curable wax and optionally at least one photoinitiator. The ink composition or overcoat composition may be curable upon exposure to radiation. The methods may further include providing a micro-roughness to one or more portions of the ink composition or overcoat composition by non-uniformly curing the ink composition or overcoat composition, and flood curing the ink composition or overcoat composition to complete a cure. The methods may thereby provide a controlled gloss level to the image.

Set forth is a method of forming an electrophoretic display device that includes locating a multiplicity of individual reservoirs containing a display fluid between conductive substrates, at least one of which is transparent, to form a device, wherein the display fluid comprises at least two sets of particles in a liquid medium, the at least two sets of particles exhibiting a different color, and charging each of the sets of particles to have a different charge via application of an electric field to the device. This field induced charging of the sets of differently colored particles enables low conductivity particles with superior electrophoretic mobility to be achieved.

Urea-urethane gellant compositions and methods of preparing the urea-urethane gellant compositions. The method includes adding an isocyanate, an alcohol or a diamine, and a solvent to a reaction vessel; stirring the reaction vessel at either ambient or elevated temperature; isolating an intermediate product from the reaction vessel; and converting the intermediate product to the organic gellant. The urea-urethane gellants are prepared in a manner to control the molecular weight and control the formation of dimers and trimers. The gellants may be used in curable gel inks.
摘要:
A method of displaying an image in an electrophoretic display device includes charging each of the sets of differently colored particles to have a different charge through application of an electric field to the display fluid or the device, and then applying an electric field to selected ones of the multiplicity of reservoirs to effect movement of one or more of the differently colored sets of particles in the display fluid therein to display a desired color derived from among the sets of differently colored particles. The colors are shown by way of the particle set or sets moved to be closet to the viewing side conductive substrate of the device. The device may include at least one display layer, including a multiplicity of individual reservoirs containing a display fluid, between conductive substrates, at least one of which is transparent and thus may be a viewing side substrate, wherein the display fluid includes at least two sets of particles in a liquid medium, the at least two sets of particles exhibiting a different color.
