PURPOSE:To stably improve an antistatic function without spoiling functions even if a photographic film having high sensitivity and high grade is contained in a magazine by treating a light shielding member with an antistatic agent. CONSTITUTION:The antistatic agent to be used for treating the light shielding member having piles with the antistatic agent includes all the agents generally known as the antistatic agent and is exemplified by an anionic surface active agent, cationic surface active agent, amphoteric surface active agent, nonionic surface active agent and further high-polymer surface active agent. The anionic surface active agent is exemplified by the surface active agent contg. an acidic group such as carboxylic group like, for example, alkyl carboxylate. The cationic surface active agent is exemplified by alkylamine salts, aliphatic or heterocyclic quaternary ammonium salts, etc. One kind of the antistatic agent may be used alone. The use thereof in conjunction with >=2 kinds such as, for example, the combination use thereof with the anionic surface active agent and the nonionic surface active agent and the combination use with the cationic surface active agent and the nonionic surface active agent are also possible. |
