A holographic recording medium composition contains an isocyanate group-containing compound (component (a-1)), an isocyanate-reactive functional group-containing compound (component (b-1)), a polymerizable monomer (component (c-1)), a photopolymerization initiator (component (d-1)), and a stable nitroxyl radical group-containing compound (component (e-1)). A ratio of the total weight of a propylene glycol unit and a tetramethylene glycol unit that are contained in the component (b-1) to the total weight of the component (a-1) and the component (b-1) is 30% or less.

Composition for holographic recording medium, cured product for holographic recording medium, and holographic recording medium

A composition for an organic electroluminescent device is a composition for forming an organic light emitting layer of an organic electroluminescent device by wet coating process. The composition contains a phosphorescent material, a charge transport material, and a solvent, in which the phosphorescent material and the charge transport material are each an unpolymerized organic compound, and the first oxidation potential of the phosphorescent material E, the first reduction potential of the phosphorescent material E, the first oxidation potential of the charge transporting material E, and the first reduction potential of the charge transporting material Esatisfy the following condition: E+0.1&#x2266;E&#x3c;E&#x2266;E&#x2212;0.1 or E+0.1&#x2266;E&#x3c;E&#x2266;E&#x2212;0.1.
