PURPOSE:To reduce a ghost due to unnecessary reflection by providing a light reflection preventive film to a dry plate for hologram recording. CONSTITUTION:The light reflection preventive layer 17c is formed on the opposite surface of the base 17b of the hologram recording dry plate 17 from its photosensitive material surface 17a. Thus, the reflection preventive film 17c is provided to eliminate reflected light due to reflection on the reverse surface of the dry plate, so this reflected light and other light do not interfere with each other, so an unnecessary image is prevented from being recorded. Consequently, the resulting ghost is reduced. Further, even when the light reflection preventive layer 17c is provided not only on the opposite surface from the photosensitive material surface 17a, but also between the photosensitive material and substrate or on the surface of the photosensitive material, ghost due to reflection on the surface is reduced. |
