Embodiment

[0211] The invention can be better understood by reference to the following specific embodiments. The suffix (C) designates a control or comparative color negative, while the suffix (E) designates an example color negative.

[0212] All coverages are in g / m 2 Units are reported in parentheses unless otherwise stated. Silver halide coverage is expressed in terms of silver. The symbol "M%" means mole percent. ECD and t represent average particle size. The halides in the mixed halide grains and emulsions are listed in order of increasing concentration. The gamma (γ) for each color record is the maximum slope of the characteristic curve between a point on the characteristic curve at a density of 0.15 above the minimum density (Dmin) and a point on the characteristic curve at a higher exposure level of 0.9 logE, where E is the exposure in lux-seconds.

Abstract

A color negative photographic element especially suited for preloading in a one-time-use camera is disclosed. The element is capable of producing images that, when developed, converted to electronic form, and then converted to a viewable form, exhibit excellent color, reduced granularity, and improved sharpness. The photographic elements contain blue, green, and red recording layer units capable of forming spectrally differentiated dye images. The layer units are substantially free of colored masking coupler, and each exhibits a dye image gamma of less than 1.5. The element exhibits an exposure latitude of at least 2.7 log E. The gamma ratios of the blue, green, and red recording layer units are between 0.80 and 1.2. Chemical processing of the element is also disclosed.

Description

technical field [0001] This invention relates to color negative film and its chemical processing. The film is particularly suitable for loading into a single-use camera and it is desired to form an image for scanning, electronic processing, and conversion into a visible form. Background technique [0002] The term "one-time use camera" or "OTUC" is used to denote a camera supplied to the user with a lens and shutter preloaded with a light-sensitive silver halide photographic element. The terms "single-use camera," "film unit with lens," "disposable camera," etc. are also used in the art as a camera that is intended to be used only once, after which it is recycled and the film is then removed for development. [0003] The term "E" is used to denote exposure in lux-seconds. [0004] The term "gamma" is used to denote the increase in image density (ΔD) produced by a corresponding log increase in exposure (Δlog E) and to indicate the maximum gamma measured over the entire rang...
