BOOKLET HAVING ANTI-COUNTERFEITING FUNCTION, AND METHOD FOR PRODUCING SAME

摘要

A booklet is provided including at least a sheet-like first substrate, and a sheet-like second substrate that is attached to the first substrate. The first saddle-stitch substrate includes a light-transmitting region, and an optical functional unit having a polarization or phase modulation function is provided to the light-transmitting region. In the second saddle-stitch substrate, a latent image, which is manifested by allowing the optical functional unit to operate, is provided to a surface that is opposite to the first saddle-stitch substrate at a position corresponding to the optical functional unit.
