<p>PURPOSE:To provide an ink compsn. which allows clear writing to be carried out even on adhesive tapes and is suitable for use as ink for writing utensils, by mixing a resin soluble in aliph. and/or alicyclic hydrocarbon solvents, a pigment, an extender pigment and an aliph. and/or alicyclic hydrocarbon solvent. CONSTITUTION:A resin (A) (e.g. alicyclic hydrocarbon resin) soluble in aliph. hydrocarbon and/or alicyclic hydrocarbon solvents, a pigment (B) (e.g. titanium oxide or carbon black), an extender pigment (C) selected from among metallic soap (e.g. calcium stearate), calcium carbonate, magnesium carbonate, aluminum silicate, calcium silicate, magnesium silicate, silicic acid, hydrated aluminum, barium sulfate and calcium sulfate, and aliph. hydrocarbon and/or alicyclic hydrocarbon solvents (D) (e.g. cyclohexane, petroleum benzine) are mixed together to obtain the desired ink compsn.</p> |
