Dai Nippon Printing is the first company in the world to succeed in the mass production of full-color 3D Lippmann type holograms, which are marketed under the name of TRUE IMAGE TM . TRUE IMAGE TM labels consist of a panchromatic photopolymer material and pressure-sensitive adhesives (PSAs). This new medium is expected to have wide application in various fields, such as publishing, labels for authentication, and so on. For commercial use, TRUE IMAGE TM labels require high-quality PSAs. In this study, two new PSAs and a new layer structure were developed. One PSA provides TRUE IMAGE TM labels with good environmental stability, and the other adjusts the playback wavelengths. These two PSAs together with a new layer structure have enabled the development of a new type of TRUE IMAGE TM label for security applications.
