Self-processing photographic film unit with nonwoven cloth in trap |
摘要 |
A self-processing photographic film unit has a trap member using a nonwoven cloth in order to catch surplus processing solution. This nonwoven cloth is provided with a polymer having carboxyl groups, and a hardening agent for hardening the polymer in order to prevent leakage and change of color to a frame portion of an image forming plane. A nonwoven cloth according to another embodiment includes a fiber of duplex structure which comprises an external layer of a hydrophilic cross linkage polymer and an internal layer of an acrylonitrile type polymer. A further embodiment includes a nonwoven cloth having dimensions of individual gaps or density which are changed stepwise or continuously. This nonwoven cloth is stored in the trap section so that a portion having a small density or large individual gaps is disposed on the inlet side.
