Photochemical formation of image with nonlinear optical and photorefractive properties in polymer layers is displayed. The layers were obtained using composition of polyhydroxyaminoether containing aromatic amino groups in polymer chains and tetrabromomethane. Donor-acceptor complexes form in the layers and irradiation of the layers by light in the range 330-450 nm stimulates electron transfer from the donor to the acceptor leading to the synthesis of colored polycation product which possesses the nonlinear optical and charge carrier photo-generating properties. Besides, these layers are electron-transporting ones. All of it allowed to obtain light-sensitive layers for recording nonlinear optical and photorefractive images and patterns.
