<p>PROBLEM TO BE SOLVED: To recognize multi-color display character or image in the case of observation through a polarizing plate or observation by means of a radiation with a linear polarized light through the character or the image cannot be recognized at the time of observation under a natural light. SOLUTION: A security product 10 is constituted by providing a base material 11, three-layered dichroic coloring matters 13, 15 and 17 being mutually different in color, which are formed on the material 11, and optical activated molecular layers 12, 14 and 16 formed among the three layered coloring matters. The anisotropically oriented dichroic coloring matters are patterned in each dichroic coloring layer. Though the character or the image cannot be recognized by observation under the natural light, each patterned part is differently colored and recognized since a deviation exists in the polarizing components of a transmissive light when the security product 10 is observed through the polarizing plate placed in a horizontal or vertical direction.</p> |
