The research of polymer materials with advanced performance for information recording is an active branch in material science and photonics. The series of carbazole‐containing compounds: poly‐epoxypropylcarbazole (PEPC), poly‐epithiopropylcarbazole (PETPC), and copolymers of PETPC:glycidyl butyrate (PETPC:GB) were synthesized and investigated. The presented characteristics of thin films structures based on polymers mentioned above show the possibility to use them for both holographic and e‐beam recording. The interesting feature has been found concerning the formation of hidden gratings which have been revealed only by etching.
