Title:
SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL
Document Type and Number:
Japanese Patent JP3871355
Kind Code:
B2
Abstract:
PURPOSE: To exchange mounting tools of an automatic exposure device without causing edge fog of a rolled photosensitive material even in a bright room by controlling the reflection density of the emulsion layer side through a supporting body and the reflection density of the back coating layer measured through the supporting body to specified values or higher.
CONSTITUTION: The reflection density of the emulsion layer side through the supporting body is controlled to ≥0.8 and the reflection density of the back coating layer through the supporting body is controlled to ≥0.5. It is necessary to control the reflection density of the emulsion layer side through the supporting body of a planographic printing plate to ≥0.8 because to obtain also a halation preventing effect during exposure. Especially, by controlling the reflection density of the back coating layer through the supporting body to ≥0.5, the effect is obtd. If the reflection density of the emulsion layer side through the supporting body is ≤0.8 and the reflection density of the back coating layer through the supporting body is ≤0.5, the image quality after plate making is largely decreased and fog on the edge of a rolled photosensitive material is easily caused during mounting tools of an automatic exposure device are exchanged in a bright room.
