High stability printing liquid, intended more particularly for printing by ink jet

摘要

The invention relates to a high stability printing liquid, intended more particularly for printing by ink jet. The ink is in the state of a micro-emulsion formed by a dispersing phase containing a group of inter-compatible constituents and a dispersed phase containing a second group of inter-compatible constituents, the constituents of the first and second groups being incompatible with one another. These two phases are separated by an interfacial liquid containing surfactant molecules in such a way that the dispersed phase is in the form of globules of 500 to 1000 Angstrom. The invention is more particularly applicable to printing by ink jet.
