Abstract
A reflectance of an optical recording medium provided with a light transmission substrate on which a recording film containing a dye material is formed is controlled or regulated by providing a recording film which is formed by a method comprising the steps of preparing a solution containing only a non-aggregated portion of a dye material and a solution containing only an aggregated portion of a dye material, mixing both the solutions with a predetermined mixing ratio to prepare a mixture solution and coating the mixture solution on a surface of a light transmission substrate to form a recording film of an optical recording medium having a predetermined reflectance by changing the mixing ratio. The aggregated portion of the dye material is a metal phthalocyanine aggregated material represented.
