<p>PURPOSE:To provide the titled ink capable of developing an image fringed with clear fringe having various colors even on a nonabsorbing writing surface, by adding gold or silver powder imparted with incompatibility and repellent property, a pigment, a light-resistant organic pigment or an oil-soluble dye, and a specific surface active agent to an organic solvent. CONSTITUTION:The objective ink is produced by mixing (A) gold or silver powder pigment (e.g. having particle diameter of <=50mu) surface-treated with an agent to impart incompatibility and repellency (e.g. dimethylpolysiloxane), (B) an organic pigment (e.g. processed pigment obtained by coating a clear pigment having diameter of <=0.1mu with a resin), (C) an oil-soluble dye, and (D) a specific surface active agent, in (E) an organic solvent (e.g. an alcohol having a boiling point of 50-250 deg.C). EFFECT:A brilliant color effect can be achieved by the fringed image.</p> |
