摘要:
An ink including at least one first reactive component, at least one second component comprising a triggerable component, at least one third reactive component, and an optional colorant; wherein the at least one first reactive component and the at least one third reactive component are capable of reacting with one another to form a solid ink on a substrate; wherein the at least one first reactive component is encapsulated in a microcapsule; wherein the ink can be jetted onto a substrate and treated whereby the treatment causes the at least one triggerable component to trigger the rupture of the microcapsule thereby releasing the at least one first reactive component from the microcapsule so that the at least one first reactive component and the at least one third reactive component come into contact, react, and polymerize thereby curing the ink.
摘要:
Disclosed is a phase change ink composition comprising a phase change ink carrier and a compound of the formula and dimers thereof, wherein R, R′, X, (Y)m; and (Z)n are as defined herein.
摘要:
A method of making a phase change ink composition includes adding to a device with a stirring element at least one pigment, at least one dispersant and at least one synergist, processing the device at an elevated temperature and at a stirring rate to wet the at least one pigment to obtain an ink concentrate, and mixing the ink concentrate with an ink vehicle to obtain the ink composition. The device may be an extruder, an attritor or the like. The method allows for the reduction in the amount of dispersant to include in the ink.
摘要:
A phase change ink composition includes an ink vehicle and at least one pigment, wherein the ink composition is substantially solid at room temperature and includes at least one dispersant for the at least pigment and at least one synergist.
摘要:
A phase change ink composition, comprising an anti-drool additive to prevent and/or reduce printhead and nozzle contamination in ink jet printers caused by drooling and fouling of the faceplate by the ink. In particular, there is provided sulfonated small molecules for use in phase change ink compositions and which are compatible with phase change ink components.
摘要:
Disclosed is a compound of the formula and dimers thereof, wherein R, R2, X and Z are as described herein. The compounds are useful as colorants, particularly in applications such as phase change inks.
