BIREFRINGENCE PATTERN MEMBER AND METHOD FOR MANUFACTURING THE SAME |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a birefringence pattern member in which a latent image to be actualized at the time of identification has high identification and a high forgery prevention effect is obtained. <P>SOLUTION: In the birefringence pattern member obtained by forming at least one optical anisotropic layer 12 formed from the same layer forming composition and including two or more regions having respectively different birefringence properties in the layer on a light reflecting layer 11, the reflectance of mirror surface luminance of the light reflecting layer 11 is 8% or more. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
