<p>PURPOSE:To obtain the subject ink containing a lower saturated monohydric alcohol solvent, a metal complex salt type oil-soluble dye, a specific decaglycerin fatty acid ester and an alcohol-soluble resin, excellent in solubility, high in script concentration and hardly causing whitening phenomenon. CONSTITUTION:The objective ink is obtained by blending (A) 40-90wt.% (based on total amount of ink) 1-5C saturated monohydric alcohol solvent (e.g. methanol), (B) a metal complex salt type oil-soluble dye (e.g. Vali Fast Black 1802), (C) 0.01-1.00wt.% decaglycerin fatty acid ester having 11.0-18.0wt.% HLB value (e.g. decaglym 1-L) and (D) 1-30wt.% alcohol-soluble type resin (e.g. rosin) and as necessary stain-proofing agent, wetting agent, etc.</p> |
