AI Technical Summary

Problems solved by technology

Using this film can significantly reduce the failure caused by the failure of the flash or the poor color tone caused by the fluorescent light, but occasionally there is a problem of insufficient cloudy sensitivity
[0010] Of course, for these problems, high sensitivity is required, but from the perspective of versatility, it is not ideal because it will cause side effects such as graininess deterioration at the same time.
[0011] Furthermore, if the granularity is to be improved, it will bring about an increase in the amount of coated silver or an increase in film thickness, which is not ideal in terms of rapid development or low replenishment of the treatment solution.

Embodiment 1

[0512] With reference to the manufacturing method of Em-A to Em-O described in Example 1 of JP 2001-281815 A, the silver halide (silver iodobromide) emulsions Em-A to Em-O described in Table 1 were prepared.

[0513] Emulsion name

[0514] In Table 1, when observed with a high-voltage electron microscope, the transposition line described in JP 3-237450 can be observed in the flat particles.

[0515] (Production of sample 001)

[0516] A multi-layer of each layer of the following composition was coated on a cellulose triacetate support to produce a color negative film (Sample 001).

[0517] (Composition of photosensitive layer)

[0518] ExC: Cyan hair coloring agent UV: Ultraviolet absorber

[0519] ExM: Magenta hair coloring agent HBS: High boiling point organic solvent

[0520] ExY: Yellow hair coloring agent H: Gelatin curing agent

[0521] (The specific compounds are as follows, and the numerical value is attached after the label, and the chemical formula is also list...

Embodiment 2

[0858] Samples 101-108 were loaded into Fuji Color "UTSURUNDESU Simple Eye 800", and the same test as in Example 1 was performed. As a result, as in Example 1, the color negative photosensitive material of the present invention showed good results.

Embodiment 3

[0860] The emulsions used in this example are silver halide (silver iodobromide) emulsions Em-A to Em-O described in Table 1 of Example 1.

[0861] (Production of sample 1001)

[0862] The cellulose triacetate support was coated with multiple layers of the following composition to prepare a color negative film (sample 1001).

[0863] (Composition of photosensitive layer)

[0864] The main raw materials used in each layer are divided into the following categories.

[0865] ExC: Cyan hair coloring agent UV: Ultraviolet absorber

[0866] ExM: Magenta hair coloring agent HBS: High boiling point organic solvent

[0867] ExY: Yellow hair coloring agent H: Gelatin curing agent

[0868] (The specific compounds are as follows, and the numerical value is attached after the label, and the chemical formula is also listed later)

[0869] The number corresponding to each component is expressed in g / m 2 The amount of coating expressed in units is the amount of coating converted to silver for sil...

Abstract

In the silver halide color photosensitive material comprising at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one blue-sensitive silver halide emulsion layer on a support, and having an ISO sensitivity of >=1,000, the ISO sensitivity is >=1.25 times an indicated speed.

Description

Technical field [0001] The invention relates to a color photographic photosensitive material, in particular to a color photographic photosensitive material suitable for shooting in cloudy days or night scenes, in particular to a color negative film for still photography. [0002] In addition, the present invention also relates to a photographic product containing the color photographic photosensitive material, particularly a color negative film for still photography. Background technique [0003] In recent years, with the variability of small cameras, high-magnification varifocal cameras such as 3x and 4x focal lengths are becoming the mainstream in the market. Although these zoom cameras can easily enjoy the fun of taking pictures, it is actually difficult to call them a camera that fully meets the requirements for image quality. For example, it is also expected that the F value of the far side lens exceeds 10, which is likely to cause underexposure. In addition, because the dis...
