Problems solved by technology

The inventors of the present application conducted in-depth research based on the foregoing, and as a result, it was confirmed that the processes of developing silver formation, dye formation and conversion into optical density cannot be effectively realized when processed rapidly by the aforementioned disclosed technology, and the common problem arising is that these processes The process greatly affects the stability of photographic materials, specifically, the process variation of photographic materials with different storage conditions before exposure
[0008] In addition, in the above-mentioned processed silver halide color photographic material, valuable resources such as silver are discarded or a part thereof is recovered after processing, so that the recycling rate thereof is still low.

Embodiment 3

[0350] The photographic samples made in Examples 1 and 2 were individually converted and packaged in cassettes according to the 135 size film standard. Using these film samples and a single-lens reflex camera equipped with a 35mm focal length and F: 2 lens (F4, product of Nikon Corp.), 5 scenes including people, flowers, green plants, distant mountains and blue sky A photograph was taken with the ISO speed set to 800. The exposed film samples were then color developed according to the methods described in Examples 1 and 2 without further bleaching, fixing and stabilization processes to obtain developed samples with developed silver and silver halide remaining therein.

[0351] From the film thus developed, a 2048×2048 pixel monochrome CCD camera (KX4, obtained from Eastman Kodak Co.) was used to obtain R, G and B separated negative images, wherein the red separation filter (gelatin filter W26, obtained From Eastman Kodak Co.), a green separation filter (W99) or a blue separat...

Abstract

A color image forming method is disclosed, comprising exposing a silver halide color photographic material and developing the exposed photographic material at 43 to 180 DEG C to form a color image, wherein when the photographic material is exposed so that the light-sensitive layer has a transmission density of a minimum density plus 0.1, the light-sensitive layer comprises dye-clouds having an average diameter of 3.0 to 20.0 mum. There is also disclosed a digital image forming process, wherein image recording information of the photographic material which was formed by use of the color image forming method is converted to digital image information through an image sensor.

Description

field of invention [0001] The invention relates to a color imaging method of a silver halide color photographic material and a digital imaging method using it. Background of the invention [0002] A silver halide photographic photosensitive material (hereinafter, also simply referred to as a photographic material) is used as a recording material, which is simple and low-cost and can provide high-quality images. These materials have greatly contributed to the progress of industry and culture, and thus have become indispensable materials. [0003] Silver halide color photographic elements, such as color negative films, are exposed and then color developed to form yellow (Y), magenta (M) and cyan (C) dye images together with a silver image, followed by bleaching to bleach the silver image to silver halide . The silver halide so formed becomes a soluble silver complex and is removed from the photographic element. The photographic element is further stab...
