1. jetted ink, comprises:

  • Dicyandiamide solution;

    Be dispersed in particle diameter and at least 2 g/cm with at least 0.2 μ

    m in this dicyandiamide solution 3the pigment of density;

    With Comprise many ethoxylated alcohols, the surfactant of at least one in betaine type amphoteric surfactant that alkyl replaces and oxidation oleyldimethylamine, this surfactant exists by the amount being less than 30 % by weight, this amount is enough to give this ink composite and improves and the viscosity of reduction along with shear rate, and said composition is had at 1 s -1shear rate under be greater than 100 centipoises dynamic viscosity and 10,000 s -1shear rate under the dynamic viscosity of 1-10 centipoise.
