摘要 |
In a recording material which comprises a substrate, a first stabilizing layer on said substrate, a low toxicity metallic recording layer on a surface of said first stabilizing layer opposite said substrate and a second stabilizing layer on a surface of said metallic recording layer opposite said first stabilizing layer, the improvement wherein the first stabilizing layer between the substrate and the low toxicity metallic recording layer is composed of an auxiliary metal oxide layer as an upper layer and an inorganic compound layer as a lower layer for converting said auxiliary metal oxide layer to a surface-flat glassy material. Such an improved recording material can form, upon exposure to, e.g., a laser beam, excellent holes free of irregularities in shape or profile of hole.
