摘要:
The phase change ink a viscosity of from about 4 mPa-s to about 50 mPa-s at a first temperature and has a viscosity of from 104 mPa-s to about 109 mPa-s at a second lower temperature. The second temperature may be below the first temperature by at least 10° C. but by no more than 50° C. The first temperature may be from about 60° C. to about 110° C. and the second temperature may be from about 20° C. to about 70 ° C. A curve of log10 viscosity of the phase change ink plotted against temperature in degrees Celsius may have a slope having an absolute value less than 0.02 at the first temperature and have a slope having an absolute value greater than 0.08 for at least a region second temperatures.

摘要:
An ink jet ink includes an ink vehicle, wherein the ink vehicle includes at least one wax monomer functionalized to include in the chain at least one reactive group curable upon exposure to radiation. The reactive group is preferably curable via cationic or free radical polymerization. In a preferred embodiment, the ink vehicle includes a wax monomer having a structure: wherein C represents a cationically curable group and R represents a radically curable group. The inks may be used to form an image by jetting the ink onto a transfuse member surface, increasing the viscosity of the ink upon the transfuse member surface, subsequently transferring the ink from the transfuse member surface to an image receiving substrate, and exposing the ink to radiation following the transfer to the image receiving substrate to effect reaction of the at least one reactive group.
摘要:
An ink that may be used in ink jet devices is a photochromic ink comprising an ink vehicle that includes at least one radiation curable component, at least one photochromic material and at least one photoinitiator. The ink is cured via exposure to radiation that cures the at least one radiation curable component of the ink. A radiation curable ink capable of exhibiting photochromatic color changes, which may be used to indicate a document's authenticity, is thus achieved.
