ABSTRACT:
An optical recording medium comprising a substrate (1), a colorant recording layer (2) on and from which information is capable of being recorded and reproduced, provided on said substrate (1), an intermediate layer (3) provided on said colorant recording layer (2), said intermediate layer (3) comprising a material that is transparent to recording-reproducing light, has a lower refractive index than that of a colorant contained in said colorant recording layer (2) and is soluble to an aliphatic or alicyclic hydrocarbon solvent, and a metal reflective layer (4) provided on said intermediate layer (3). A useful process for producing such a optical recording medium is also disclosed.
