Abstract

An optical assembly includes a spacer layer which is translucent or transparent; an image forming reflector which has a reflective layer being formed at least in a first region of the spacer layer; and a protective layer which is laminated over the spacer layer and the image forming reflector and the protective layer being translucent or transparent. The spacer layer is made of a polyolefin or/and a polymer containing an aryl group. The image forming reflector includes a visible image which is authenticatable. The image forming reflector has an individual information record in which a code is stored in the form of a plurality of removed linear segments. The image forming reflector has white level regions and a black level region in planar view. Each of the white level regions has the removed linear segments formed therein. The black level region is interposed between the white level regions.
