<p><P>PROBLEM TO BE SOLVED: To provide a transfer foil which is not destroyed even on a fibrous base material having stretching properties such as a cloth, and a hologram medium using the same. <P>SOLUTION: In a hologram medium, a hologram layer is provided on a base material made of a fiber. The hologram layer includes a diffraction structure and a metallic reflective layer formed on the diffraction structure and composed of a plurality of divided patterns. Each of the patterns of the metallic reflective layer has a pattern diameter smaller than a yarn diameter of yarn, which is made of a single fiber or made by twisting a plurality of fibers, and equal to or larger than a pitch of a fundamental periodic structure of the diffraction structure. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
