ABSTRACT:
An optical information memory medium comprising a substrate, an improved underlying layer formed on the substrate surface, and a recording layer formed on the underlying layer and mainly consisting of an organic pigment is disclosed. In this optical information memory medium, the underlying layer is formed by causing a compound containing a hydroxyl or carboxyl group selected from the group consisting of a radical polymerizable monomer containing a hydroxyl or carboxyl group, a copolymer obtained from a monomer containing a hydroxyl or carboxyl group, and a polymer compound containing a hydroxyl or carboxyl group to react with a hydrolyzed condensate which is derived from an alkoxide or an aryloxide of a metal selected from the group consisting of Al, Ti, Zr, In, Zn, Mg, Ni, and Cu or from a chelate compound mainly consisting of the metal. An underlying layer formed of a hydrolyzed condensate which is derived from the alkoxide or the aryloxide of a metal selected from the group consisting of Al, Ti, Zr, In, Zn, Mg, Ni, and Cu is also disclosed.
