Phase change inks

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.
