OPTICAL INFORMATION RECORDING MEDIUM

摘要

PURPOSE:To enable the film formation by a spin coating method and to facilitate production by forming the dyestuff material constituting a light absorptive layer so as to be insoluble in the solvent of an enhancement layer material constituting a light reflection assisting layer. CONSTITUTION:Such a combination that is entirely insoluble in the solvent of the enhancement layer material constituting the light reflection assisting layer 4 is selected for the dyestuff material constituting the light absorptive layer 3 of the optical information recording medium 1. As a result, the run-off of the light absorptive layer and the dyestuff material thereof does not arise at the time of spin coating of the enhancement layer material on the light absorptive layer and the film formation of both the light absorptive layer and the light reflection assisting layer by the spin coating method is possible. Then, the optical information recording medium with which the production is easy and which is inexpensive is obtd.
