    摘要： An ink including stabilized magnetic single-crystal nanoparticles, wherein the value of the magnetic anisotropy of the magnetic nanoparticles is greater than or equal to 2 x 10 4 J/m 3 . The magnetic nanoparticle may be a ferromagnetic nanoparticle, such as FePt. The ink includes a magnetic material that minimizes the size of the particle, resulting in excellent magnetic pigment dispersion and dispersion stability, particularly in non-aqueous inkjet inks. The smaller sized magnetic particles of the ink also maintains excellent magnetic properties, thereby reducing the amount of magnetic particle loading required in the ink.

    摘要： An ink preferably used in piezoelectric ink jet devices includes an ink vehicle that includes at least one curable monomer, at least one polymerizable organic gelator, at least one initiator, at least one colorant and optionally at least one low molecular mass non-reactive organic gelator and/or at least one thermal solvent. The use of the curable gelator enables the ink to form a gel state having a viscosity of at least 10 2.5 cps at very low temperatures of about 30°C to about 50°C. The ink may thus be jetted at low temperatures of about 50°C to about 90°C. The ink is heated to a first temperature above the gel point of the ink, jetted onto a surface maintained at a second temperature at which the ink forms a gel state, and when on the image receiving substrate, is exposed to radiation energy to polymerize the polymerizable components of the ink.

    摘要： Disclosed is an ink composition which comprises an aqueous liquid vehicle, a colorant, and a phosphate ester. The inks described are particularly suitable for ink jet printing processes, especially thermal ink jet printing processes. The inks exhibit low viscosities and rapid drying times, particularly on plain paper. Also disclosed is a process for generating images on a substrate, which process comprise incorporating such an ink into an ink jet printing apparatus and causing droplets of the ink composition to be ejected in an imagewise pattern onto the substrate.
