Photosensitive information carrier

摘要

The invention relates to photonics and optoelectronics, namely to a photosensitive information carrier.The photosensitive information carrier, according to the invention, includes an optically transparent substrate of polyethylene terephthalate or glass, on which is deposited a photosensitive layer of copolymer 9-carbazolylmethylthiiran-glycidyl butyrate proceeding from the following ratio of monomers, mol %:sensitized with triiodomethane, taken in the quantity of 8...10% of copolymer weight.The result is to increase the photosensitivity of the information carrier and 1.5...2 times the diffraction efficiency as compared with the closest analog.
