期待され、商品化段階を迎えている。[Prior Art] Magneto-optical recording media utilize perpendicular magnetic recording and magneto-optical effects, and as with conventional optical recording media, information is recorded and reproduced using laser light, so they have a large recording capacity. Can be rewritten. Furthermore, recording and reproduction can be performed without contact between the head and the medium, and it is not affected by dust, so it has excellent stability. This magneto-optical recording medium is currently being actively researched.
It is expected to be used for video still image files, computer memory, etc., or as a replacement for floppy disks and hard disks, and is now at the commercialization stage.

ディスクの逆反りが生じ問題である。[Problems to be Solved by the Invention] However, the conventional optical recording medium described above has a protective layer made of a cured product of the ultraviolet curable acrylate resin composition, thereby providing protection against external scratches and stains. Although this objective was achieved, the optical recording medium was subjected to an environmental durability test (70
C., 90% RH, 2000 hours), there is a problem in that the pitting corrosion deterioration of the magneto-optical recording layer may increase or the protective layer may peel off from the disk substrate. Further, when a protective layer made of a cured product of an epoxy resin composition is provided, pitting corrosion deterioration of the magneto-optical recording layer is less likely to occur, but reverse warping of the disk occurs, which is a problem.
