Crosslinkable photosensitive materials have been studied for many years and they are widely used for optical recording of information. After investigating the photochemical process in various systems, it appears that the chemical structure of the polymeric matrix plays an essential role in the process of the reaction that takes place upon irradiation by a laser beam. The results of experiments that were conducted to investigate the possible use of different sensitizers and different mixtures of polymers are presented in this paper. Also, some applications that were studied using such crosslinkable systems as volume hologram as well as surface relief structure recording material are presented.
