PURPOSE:To easily produce the recording medium by a coating method by constituting an antireflection layer of the cured matter of a monomer or oligomer having polymerizable double bonds and specifying the properties thereof. CONSTITUTION:The antireflection layer is constituted of the monomer and/or oligomer having the polymerizable double bonds and has the refractive index in the range satisfying equation I and the layer thickness in the range satisfying equation II. In the equation I, ns denotes the refractive index of a substrate; n denotes the refractive index of the antireflection layer. In the formula II, lambdadenotes the wavelength of a laser used for reproduction; n denotes the refractive index of the antireflection layer; d denotes the layer thickness of the antireflection layer. Thus, the resin of the antireflection layer is easily formed by applying the resin on the substrate surface and drying the coating. |
