<p>PURPOSE:To provide a jet printer ink excellent in adhesiveness to metals and resistance to alcohols, also good in jet stability, comprising a colorant, a combination of each specific two kinds of resins, organic solvent and electrical conductivity-imparting agent. CONSTITUTION:This jet printer ink comprises (A) a colorant (pref. pigment), (B) (1) a hydroyl group-bearing vinyl chloride-vinyl acetate copolymer and (2) a dicyclopentadiene resin at the weight ratio (1)/(2) of pref. 100:(10-50), (C) an organic solvent (pref. that containing methyl ethyl ketone) and (D) an electrical conductivity-imparting agent (pref. a quaternary ammonium salt of organic anion). To improve the stability of the ink, it is preferable that an epoxy-based stabilizer for vinyl chloride be additionally incorporated in the composition.</p> |
