<p>PURPOSE: To obtain thermoplastic polymer microparticles for jet inks being excellent in solvent resistance, flexibility and deflection, not causing the plugging of an ink jet nozzle and giving excellent printed coating films and to obtain an ink containing the same and used for ink jets. CONSTITUTION: This thermoplastic polymer microparticles for jet inks containing a colorant within each particle, having a mean particle diameter of 5-700nm, a max. particle diameter of 1,000μm or below, a particle diameter distribution corresponding to a Weibull probability distribution in which the shape parameter m is 1.3 or above, having film-forming properties at room temperature and giving a film insoluble in an organic solvent and a jet ink consisting essentially of these microparticles are provided.</p> |
