An optical information recording medium for recording and reproducing information by way of applying high density energy beams to a reflective recording layer on a support, wherein said reflective recording layer comprises a hydrophilic colloid;
- a compound capable of producing a water-insoluble copper complex;
- and reflective fine particles consisting essentially of copper.
A process for manufacturing an optical information recording medium for writing and reading information by way of applying high density energy beams to a reflective recording layer on a support, which comprises the steps of:
- providing a physical developing nuclei containing layer on a support;
- physically developing a copper compound in the presence of said physical developing nuclei to obtain said reflective recording layer;
- and adding a compound capable of producing a water-insoluble copper complex.
