An optical recording medium comprising a substrate having thereon a recording layer containing at least two kinds of dye A and dye B, wherein dye A and dye B satisfy the following conditions (1) and (2): n(1) the starting temperature of decomposition is from 150 to 250°C, n(2) refractive index n (A) and extinction coefficient k (A) of dye A at the wavelength of recording laser ray, and refractive index n (B) and extinction coefficient k (B) of dye B at the same wavelength satisfy the following expressions: n B / n A > 0.7 k B / k A > 10. |
