CONSTITUTION:An ink prepared by adding a lubricant, e.g. a fluorine-type surfactant, silicone-type surfactant, etc. to an ink consisting of a pigment as a colorant, a solvent, diluent, preservative, penetrant, etc. The basic recipe of the ink is preferably as follows: 90pts.wt. solvent, 10pts.wt. pigment, 0.05pts.wt. lubricant, 0.5pts.wt. preservative and 0.1pt.wt. rust inhibitor. EFFECT:No blurred script, change in width of written lines nor flopping down of the ink, etc. even by writing with the ink in writing utensils for a continuous long term. The abrasion of the contact surface of rubber stamps, rollers, etc. with the ink for printing is reduced.</p> |
