<p>PROBLEM TO BE SOLVED: To obtain the subject ink capable of imparting the receptivity for an ink jet ink and luminous effects, making the position known in the dark, definitely discriminating prints and aiming at a substrate for a compact disk, etc., by including a luminous pigment as a receptivity improver therein. SOLUTION: This ink is obtained by including a luminous pigment having preferably 5-35μm, more preferably 8-25μm average particle diameter such as an N selfluminous luminous pigment as a receptivity improver in an amount of preferably about 15-90 pts.wt. based on 100 pts.wt. of an ink vehicle. A hydrophilic polymer as a binder is preferably contained in the ink. The luminous pigment and a conventionally known water adsorbing or a water absorbing organic filler can be used in combination as the receptivity improver.</p> |
