Abstract

The possibility of rainbow hologram registration on a base of photothermoplastic recording media is shown. The single- layer photothermoplastic compositions consisted of polymer photoconductor-poly-N-epoxypropylcarbozole and co-polymers of epoxypropylcarbozole with alkylglytsidyl ethers sensitized to the visible by novel electron acceptors of fluorene series were investigated and used for the rainbow hologram recording. For rainbow hologram recording of diffuse object we used such photothermoplastic materials that ensure a possibility of (3-4)-fold intensification of geometrical surface relief with diffractional efficiency h greater than or equal to 4-5% without metallization at suitable signal-noise ratio. The metallization of such holograms permits us to increase h up to 20 - 30%. Both composition of photothermoplastic materials and registration regime (charging, heat development) with using multifold geometrical surface relief intensification were optimized.
