  • Patent number: 4341857
    Abstract: An improvement to instant photograph film wherein spotted uneven concentration is effectively prevented, particularly under high temperature conditions, from being produced in the image zone edge portion during the formation of images after pressure and treatment. A zone of grooves is formed, in the width direction along the cross edge portion, in at least one face of the mutually opposite faces between a first sheet and a second sheet adjacent a treating liquid container. Thus, the thickness of the spread treating liquid is made uniform and increases near the grooves to reduce the floating of the second sheet. The second sheet's floating or rising is suppressed due to the increase in contact area with the viscous treating liquid. Trapped air is caught to prevent it from reaching the image zone portion. Since a partial air layer is prevented from being formed between the first sheet and the second sheet, the spotted uneven concentration does not appear.
