  • Publication number: 20030044735
    Abstract: The invention relates to a method and device for processing an exposed colour reversal photographic film. This method enables the water consumption of the washing baths to be limited, the water levels being maintained by a counter-current coming from the bath placed downstream, an equivalent volume of water being discharged through an overflow. The wash waters are recovered and treated by a nanofiltration unit capable of giving a permeate which can be recycled to the washing baths. This method makes it possible to overcome the problem of the presence of tin (II) in the first washing bath supplied with water by a counter-current coming from the reversal bath. This process also makes it possible to overcome the problems of discharges of chemical substances to the drains while maintaining a good sensitometry of the developed films.

    Abstract: A multicolor negative photographic element comprises a support bearing a blue light-sensitive silver halide emulsion first layer and a green light-sensitized silver halide emulsion second layer wherein said second layer contains a dye sensitized to green light and wherein said first layer has associated therewith a hue correction coupler which upon coupling with oxidized developer produces a dye having a maximum absorbance in the range of 460 to 510 nm. so that the element has a D480/D440 density ratio which is greater than that exhibited by the element without the hue correction coupler. The invention also encompasses a blue sensitive silver halide emulsion layer associated with the hue correction coupler and a method of forming an image in the photographic element of the invention.
