<p>On a main surface of a security document, being a gift certificate 1, a liner pattern 2 is formed through a transparent or a semitransparent resin layer 6 on a coloring layer 5 provided on a base material 4. The coloring layer 5 has a lightness (L*) defined by CIE LAB within the range of 0-80, preferably within the range of 0-45. The pattern 2 is printed with ink containing resin, solvent and scale pigment. When the lightness (L*) of a printed surface of the pattern 2 is under 80, hue of the pattern 2 will be rich in color alteration, and it will be easy to view the hue alteration in the iridescence depending on the angle the pattern 2 is viewed. <IMAGE></p> |
