Rezumat

The photochemical method of image recording of carbazole - containing polymeric layers (f.e. PVC and its copolymers or poly -N - epoxypropylcarbazole, containing under 10% of photochemical cross-linking agents at the range of calcogen -derivatives ofmethane and etc.) attributes to well-known methods of image recording. The carbazolalkylmethacrylate (CAMC) copolymer with octylmethacrylate (OMA) photoplastic carries has been investigated in details on the purpose to enlarge the image photographic characteristics of carbasolalkylmethacrylate. The photopolymer layers were made by pouring from solutions. The structure of CAMC is 1: 1 and contains OMA varying from 0 to 5Omol%. There were additionally added about 5-16% iodinophorm CHI3 for photo-cross-linking of given copolymer layers. The best results of macromolecular photo-crosslinking in UV-rays were obtained with 60-7Omol% CAMC containing copolymers. It can be connected with good flexibility of polymeric macromolecules. Optimal concentration of iodinophorm was about 8-10%.It has been used a coherent laser beam with λ=420 nm for holographic images recording (Ne-Cd-lazer). There were obtained holographic gratings with resolution 1500 mm-1 and diffraction efficiency 23%. This material has photographic sensitivity 103 m2IJ that allows using the explored copolymers for elaboration of a new optic media for holographic images recording.
