Abrégé
A novel optical-isomer separating agent for chromatography is provided which has, as a chiral selector, a macrocyclic amide compound having the ability to function as a chiral shift agent. The optical-isomer separating agent for chromatography is formed by bonding, with a carrier by chemical bonding, a specific ring structure containing an asymmetry recognition site, an amide group as a hydrogen-bond donor site, and a hydrogen-bond acceptor site.

Provided is a transmission type volume hologram recording medium used in a two-beam hologram recording system, having a high diffraction efficiency and capable of remarkably reducing the intensity of higher order diffracted light, which is a cause of a noise, than first-order diffracted light. A transmission type volume hologram recording medium has a volume hologram recording medium layer of a volume hologram recording photosensitive composition, which is held between opposed substrates having different materials. Each of the substrates which hold therebetween the volume hologram recording medium has a transparency in a visible light area, and preferably has a thickness in the range of 2 to 2000 μm. Also, a difference in refractive index between the two substrates which hold therebetween the volume hologram recording medium is preferably 0.001 to 0.5. Moreover, preferably, a difference in thickness between the two substrates which hold therebetween the volume hologram recording medium is in the range of 1 to 1500 μm.
