Abstract

The photochemical method of image recording of carbazole - containing polymeric layers attributes to well-known methods of image recording. The CAMC copolymer with OMA photoplastic carriers has been investigated in details on the purpose to enlarge the image photographic characteristics of CAMC. The photopolymer layers were made by pouring from solutions. The structure of CAMC is 1:1 and contains OMA varying from 0 to 50mol percent. There were additionally added about 5-16 percent iodinophorm CHI₃ for photo-cross-linking of given copolymer layers. The best result of macromolecular photo-cross-linking in UV-rays were obtained with 60-70 mol percent CAMC containing copolymers. It can be connected with good flexibility of polymeric macromolecules. Optimal concentration of iodinophorm was about 8-10 percent. It has been used a coherent laser beam with (lambda) equals 420 nm for holographic images recording. There were obtained holographic gratings with resolution 1500 mm^-1 and diffraction efficiency 23 percent. This material has photographic sensitivity 10³ m²/J that allows using the explored copolymers for elaboration of a new optic media for holographic images recording.
