A problem of our everyday life, which has a negative influence upon our own health is the pollution of the environment with various waste materials of polymeric nature. At the territory of the Republic of Moldova, at densely populated areas, one can espy a numerous heaps of many-colored bags hanging on the tree branches, plastic bottles scattered around etc, etc. All these pollutants are stable in different conditions and do not decompose in the environment. Such a problem of everyday pollution may have been resolved if these materials were reutilized. Thus, reutilization and recycling of diverse materials may help to resolve simultaneously two important tasks: the ecological and economical ones. In connection with aforesaid it should be noticed that research in the field thermoplastic recording of information can resolve the both tasks by turning off from the expensive halogen-silver photoprinting, which is connected with some difficulties e.g. treating the film (developing, fixing, possibility of but single use of the information bearer. The photopolymer bearers of information are the most preferable materials for the image recording to substitute the common ones. Though photochrom bearers yield to those halogen-silver ones in photosensibility with 100-1000 times, yet they are ecologically harmless and have other advantages, such as: there is no step connected with liquid-treating of them, when recording an image, and above all they can be regenerated more than once to be record able for images for many cycles. Therefore this work is dedicated to the synthesis and investigation of some polymeric photocrom materials, derivates of pyrane and oxazine series. There is shown a possibility of their use for the registration of traditional and holographic images. It is established that maximum stability (up to 1000cicles) shows photochrom bearers – derivates of oxazine series. |
