To provide a photosensitive composition for hologram recording that enables further improvement in diffraction characteristic. A photosensitive composition for hologram recording that includes at least two kinds of photopolymerizable monomers, a photopolymerization initiator, a binder resin, and a polymerization inhibitor. The at least two kinds of photopolymerizable monomers are a monofunctional monomer and a polyfunctional monomer.

Photosensitive composition for hologram recording, hologram recording medium, and hologram

A hologram recording composition includes at least: a photopolymerizable compound containing at least a first photopolymerizable monomer; binder resin that is inactive to photopolymerization; and a photopolymerization initiator. A change in polarity of the first photopolymerizable monomer by photopolymerization reduces compatibility with the binder resin of the photopolymerizable compound than that before polymerization, the compatibility of the photopolymerizable compound before the polymerization being high.

Hologram recording composition, hologram recording medium, and method of producing hologram recording medium

There are provided a 6,12-dioxaanthanthrene derivative which is an organic semiconductor material capable of improving resistance to mechanical deformation, an organic semiconductor element, and a method for manufacturing the organic semiconductor element. The 6,12-dioxaanthanthrene derivative is represented by structural formula (1). Rand Rare photopolymerizable unsaturated groups. Rand Rare non-photopolymerizable substituents.
