An optical information recording disc is composed antransparent substrate, an information recording layer, anmetallic light-reflecting layer, a light-shielding layer,nand an ink-printable layer, in order. The light-shieldingnlayer is prepared essentially from a binder polymernand zinc sulfide particles, so that an ink, particularlynan aqueous ink solution, applied onto the ink-printablenlayer gives a clear ink image with almost no blur. |
