Samples synthesis and

There are at present several modifications of polymeric light-sensitive media on the base of phenanthrenequinone (FQ), which implement the diffusion enhancement piindple. The authors devised the technology to obtain a material, whose samples have certain holographic and physical-mechanical parameters, conditioned by modes of sample synthesis and hologram construction. The name Difphen (from words DIFfusion and PHENanthrenequinone) allows singling given material out of variety of other modifications of PQ-based polymeric medium with diffusion enhancement.
