Disclosed is a sheet for producing a multilayer optical recording medium having a repeating structure wherein a plurality of optical recording layers are laminated. The sheet for a multilayer optical recording medium has a structure having a unit wherein an optical recording layer and an adhesive layer are laminated, or a structure having a unit wherein an optical recording layer, a barrier layer and an adhesive layer are laminated in this order. The maximum height roughness (Rz) of the optical recording layer or the barrier layer is not more than 500 nm. A multilayer optical recording medium is produced by using the sheet for a multilayer optical recording medium. Also disclosed is a sheet for producing, with high precision, a high-quality multilayer optical recording medium having a repeating unit wherein a plurality of optical recording layers containing a multiphoton absorbing material are laminated. A multilayer optical recording medium is also produced by using this sheet.
A sheet for a multilayer optical recording medium having a repeating structure comprising a plurality of laminated optical recording layers, wherein the sheet has a structure comprising a unit in which an optical recording layer and an adhesive layer are laminated or a structure comprising a unit in which an optical recording layer, a barrier layer and an adhesive layer are laminated in this order, and a maximum height roughness (Rz) of the optical recording layer or the barrier layer is 500 nm or smaller.
