An organic recording medium is prevented from deterioration, and durability is improved, and a highly reliable optical recording medium and its manufacturing method are provided.n n n The recording layer 3 mainly composed of organic pigments on the substrate 2, and the reflective layer 4 made of a metal selected from Cu, Ag and Au, or an alloy containing at least one of these metals in this order. Form. After laminating an ultraviolet curable material having an organic acid content of 200 ppm by weight or less on the reflective layer 4, it is cured to form a protective layer 5 to obtain an optical disc 1. As the dye, a cyanine dye is preferable, and an alloy containing Cu, Ag, or at least one of these metals is preferable as the reflective layer.n n n n Optical recording media |
