PURPOSE:To provide the film base high in dimensional stability against change of temperature and humidity, especially, humidity and superior in light transmission in the near ultraviolet region of 350nm. CONSTITUTION:The photographic sensitive material is obtained by forming a thin film made of silicon oxide and alkaline earth metal fluoride or these and magnesium oxide on one or both sides of a plastic film and forming a photosensitive layer on one or both sides of this film base and, when needed, a conductive layer on one side. |
