<p>PURPOSE:To obtain an oily ink composition rapidly dryable when coated on a non-absorbing surface, capable of giving coating films of high adhesiveness, and readily dryable even if coated thick, comprising a pigment, nitrocellulose, and each specified amount of resin except nitrocellulose and organic solvent. CONSTITUTION:This oily ink composition comprises (A) a pigment such as an organic pigment like an azo pigment, dioxazine pigment, quinacridone pigment, styrene-, phthalocyanine-, nitroso-, nitro-based, or various dye's lake, or an inorganic pigment like carbon black, titanium dioxide, iron oxide or calcium carbonate, (B) nitrocellulose, (C) 25-60wt.%, based on the whole ink composition, of a resin except nitrocellulose such as ketone resin, phenolic resin, petroleum resin, coumarone resin, rosin-modified resin or acrylic resin, and (D) 30-75wt.%, based on the whole ink composition, of an organic solvent such as hydrocarbon-, ketone-, ester-, alcohol-, or ether-based solvent.</p> |
