摘要： A sheet for producing a multilayer optical recording medium comprises optical recording layers and adhesive layers laminated on one another, wherein the adhesive layer comprises an adhesive comprising a polymer as a main component, the polymer includes fluorine-containing monomer and/or silicon-containing monomer as a constituent monomer component, the adhesive layer has no domain structure or has a domain structure of 110 nm or less, a total content of the fluorine-containing monomer and the silicon-containing monomer is 10 to 100 mass % when a monomer total amount as the constituent monomer component in the polymer is 100 mass %. According to the sheet for producing a multilayer optical recording medium, a multilayer optical recording medium can be produced which can detect reflected light having sufficient intensity from the interface between the optical recording layer and the adhesive layer and which generates less scattered light in the adhesive layer and causes less noise.
