摘要:
Substituted oxazoline compounds and/or substituted oxazoline derivatives having amorphous, semi-crystalline, or crystalline properties and methods for producing such compounds and derivatives are presented. The substituted oxazoline compounds and/or substituted oxazoline derivatives are useful for various applications. For example, the substituted oxazoline compounds and/or substituted oxazoline derivatives may function as phase-change agents, a binder resins, rheology modifiers or plasticizers for ink compositions.
摘要:
An ink composition including one or more oxazoline compounds or oxazoline derivatives having either crystalline, amorphous or even semi-crystalline properties for use in a particular printing application, such as in a direct-to-paper print process.

摘要:
An ink composition, such as a nonpolar liquid or phase change (solid) ink composition, that includes a non-polar carrier, and a nanoscale pigment particle composition. The nanoscale pigment particle composition includes a benzimidazolone pigment and a sterically bulky stabilizer compound, which is an alkylated-benzimidazolone compound, associated non-covalently with the benzimidazolone pigment. The presence of the associated stabilizer limits an extent of particle growth and aggregation, to afford nanoscale pigment particles.
摘要:
The present disclosure provides for the process for preparing a solid inkjet ink using a pigment flush. One process includes applying a first mixing step to a pigment and a flushing agent to flush the pigment from am aqueous phase to a non-aqueous phase to form a pigment dispersion, adding at least one other ink ingredient, and incorporating the other ink ingredient in the pigment dispersion by applying a second mixing step to form a solid inkjet ink. Another process disclosed includes adding at least one ink ingredient directly to a pigment dispersion and mixing by applying a high shear mixer.
