<p>PROBLEM TO BE SOLVED: To obtain a marking ink for warning against the presence of glass, which can give a mark that is not peeled from the glass merely when it is exposed to wind and rain or when a man or a thing contacts with it softly, can be easily erased with, e.g. wet cloth even after a long time, and does not undergo sagging during the period from the transfer of the ink to its drying on the surface of the glass by using specified components as the essential components. SOLUTION: This marking ink essentially consists of a colorant (i), at least one member (ii) selected from among resin emulsions and alkali-soluble resins, a water-soluble resin (iii) in an amount to give a ratio to the solid content of component (ii) of 1/9 to 9/1 by weight, (iv) a thixotropic agent, and (v) water. Component (iv) comprises at least one member selected from among acidic heteropolysaccharides, swelling layered clay minerals and crosslinkable acrylic resin copolymers.</p> |
