A hologram recording composition having high sensitivity and capable of high multiplex recording, a hologram type optical recording medium capable of achieving high multiplex recording of interference images formed by information light and reference light, and To provide an optical recording method and an optical recording apparatus using the optical recording medium. An optical recording composition of the present invention is formed by mixing a polymerizable monomer having a functional group capable of forming a hydrogen bond and an ethylenic double bond, a prepolymer having an isocyanate group at its terminal, and a polyol. A matrix polymer. [Selection] Figure 1 |
