Picture-producing liquid medium with microcapsules for printing on paper

摘要

The liquid medium consists of a solution containing a surfactant. Two kinds of microcapsule (10C,10M,10Y), filled with two different kind of inks, are mixed with the solution. The capsule wall of the first kind consists of an artificial resin which breaks at a certain temperature and pressure to release the ink. The capsule wall of the second kind consists of a different artificial resin breaking at a different temperature and pressure. The picture creating device using this liquid medium transfers the ink selectively in accordance with two digital monochrome picture pixel signals.
