ABSTRACT:
An optical information recording medium includes a substrate, and a light absorption layer formed thereon which includes a phthalocyanine compound (I), a phthalocyanine compound (II) and a phthalocyanine compound (III) as specified in the specification. This optical information recording medium can be produced by providing the light absorption layer, directly or via an intermediate layer, on a substrate with information pits and/or guide grooves being formed on the surface thereof by film formation coating, providing a light reflection layer, directly or via an intermediate layer, on the light absorption layer by vacuum film formation, and then providing a protective layer on the light reflection layer.
