PURPOSE:To provide the titled ink which can dispense with a water supply apparatus, by adding components consisting a wetting solution to those constituting vanish for an ordinary a litho printing ink requiring dampening water. CONSTITUTION:The titled ink consists of a vegetable drying oil (A) such as linseed oil, a synthetic resin (B) such as a phenolic resin, a polyhydric alcohol (C) such as ethylene glycol, a polybasic acid (D) sach as malonic acid, a mixture (E) composed of a hexammine cabalt complex salt such as hexammine cobalt (III) chloride and a phosphate salt such as sodium dihydrogenphosphate, or a myoinsitol hexaphosphate salt (or derivative), a high-boiling petroleum solvent (F) such as spindle oil, and an emulsion (G) composed mainly of water. Wetting solution-constituting components C, D, E and E are added to a vanish-constituting component composed of components A, B and F for litho printing ink requiring dampening water to form a litho printing ink which does not require dampening water. |
