ABSTRACT
In this work we study the problem of N-vinylcarbazole copolymers sensitization using classical sensitizers like 2,4,7-trinitrofluorenone and additionally metallo-phthalocyanine such as benzoxy phthalocyanine zinc, readily soluble in organic solvents such as chloroform, toluene and others. Using the composition of N-vinylcarbazole copolymer, 2,4,7-trinitrofluorenone and benzoxyphthalocyanine copper were obtained photosensitive optical transparent layers suitable for registration of holographic images in the visible and near-infrared spectrum. Studies of the developed photopolymers photosensitivity have showed that the activation with 3–6 mass% of ben-zoxyphthalocyanine zinc does not reduce the photosensitivity in the range λ = 500–700 nm, but shift the spectral photosensitivity curve to IR domain 850–900 nm. On these photopolymers coated with a thin layer (0.6–0.8 μm) of thermoplastic were obtained high quality holographic gratings.
