PURPOSE:To form a reflection layer by a wet method by forming the reflection layer laminated on a substrate from a compsn. prepared by adding fine particles of at least one kind of a metal or a metal compd. to an org. polymer in a dispersed state and imparting particle size distribution to said fine particles. CONSTITUTION:An optical information recording medium is obtained by successively laminating an information recording layer 2 and a reflection layer 3 on a substrate. In this case, the reflection layer 3 is formed from a compsn. prepared by adding fine particles of a metal or a metal compd. to an org. polymer in a dispersed state and particle size distribution is imparted to said fine particles. Further, the reflection layer 3 is formed using an inclination material. The particle size distribution is set to the range of 0.01-1mum and the fine particles of the metal or the metal compd. are added to the org. polymer in a dispersed state. Further, the reflection layer 3 is formed from at least one kind of an org. polymer film using water containing the metal or the metal compd. as a dispersing medium. |
