An optical information recording disc is composed a transparent substrate, an information recording layer, a metallic light-reflecting layer, a light-shielding layer, and an ink-printable layer, in order. The light-shielding layer is prepared essentially from a binder polymer and zinc sulfide particles, so that an ink, particularly an aqueous ink solution, applied onto the ink-printable layer gives a clear ink image with almost no blur.
