Problems solved by technology

According to this technology, the particle size is still small, and the sensitivity can be improved, but on the other hand, fog is easy to occur, and the softening of the inert part, and further, the increase in image blur caused by pressure in particular becomes significantly larger

Embodiment 1

[0215] (Preparation of Emulsion BLA)

[0216] In a 3% aqueous solution of lime-treated gelatin, 3.5 g of sodium chloride was added, followed by 1.0 ml of N,N'-dimethylimidazolidinyl-2-thiocarbon (1% aqueous solution). An aqueous solution (Ag-1) containing 0.8 mol of silver nitrate and an aqueous solution (X-1) containing 0.8 mol of sodium chloride were added and mixed at 57° C. with vigorous stirring. Next, the aqueous solution (Ag-2) containing 0.20 mol of silver nitrate and the aqueous solution (X-2) containing 0.20 mol of sodium chloride were added and mixed at 57 degreeC, stirring vigorously. At this point, add 1×10 to X-2 -5 mol yellow blood salt. Next, the precipitate was washed with water at 40° C. to perform desalination. 80.0 g of limed gelatin was added to adjust the pH and pAg of the emulsion to 6.2 and 7.0, respectively. Add 1.6×10 cyan photosensitivity spectrosensitizing pigments A and B each -4 mol, and then, 0.4 g parts were added to reach the amount of sil...

Embodiment 2

[0498] The contents of the investigation were exactly the same as in Example 1, but the layer configuration of the coating sample was changed as follows, and the coating sample was made thinner, and the same experiment was repeated.

[0499] As a representative example, sample (210) is shown, and the content of each sample is shown in Table 6.

Embodiment 3

[0620] Using the samples (210) to (230), image formation was performed by laser scanning exposure.

[0621]As a laser light source, LiNbO with an inverted magnetic domain structure is used 3 The SHG crystal converts the wavelength of the YAG solid-state laser (946nm) with the semiconductor laser GaAlAs (808.5nm) as the excitation light source to the 473nm wavelength extracted by LiNbO with an inverted magnetic domain structure. 3 The SHG crystal uses the semiconductor laser GaAlAs (emission wavelength 808.7nm) as the excitation light source of YVO 4 A solid-state laser (an oscillation wavelength of 1064 nm) obtained by converting a wavelength of 532 nm and an AlGaInP (an oscillation wavelength of about 680 nm: model No. LN9R20 manufactured by Panasonic Corporation). Each laser beam of 3 colors moves along the direction perpendicular to the scanning direction through the polygonal mirror, so that the scanning exposure can be performed sequentially on the sample. The temperatu...

Abstract

A photosensitive silver halide material for colour photography and its imaging method are disclosed. It is composed of a substrate, 3 silver halide emulsion layers respectively containing yellow colouring agnet, pink colouring agent and green colouring agent; a colour-mixture preventing layer, a protecting layer, at least one silver halide emulsion layer containing at least one of pink colouring agents whose formula is (M-1); and at least one silver halide emulsion layer containing silver chloride and silver iodobromochloride particles. Its advantages include high developing speed and photosensitivity and low pressure fog. Its imaging method is suitable for high-light-intensity quick exposure.

Description

technical field [0001] The present invention relates to a color photographic photosensitive material, in particular to a color photographic photosensitive material with high sensitivity, rapid processing, and less pressure-induced fog. It also relates to image forming methods for color photographic photosensitive materials, especially image forming using high-illuminance short-time exposure. Background technique [0002] In recent years, in the photoprocessing service industry, photosensitive materials that can be developed quickly and have high image quality are desired as part of improving service to users and as a means of improving productivity. Currently, a photosensitive material containing a high silver chloride emulsion is processed at a color development time of 45 seconds, and the total processing time is usually about 4 minutes. (For example, color processing CP-45X manufactured by Fujifilm Co., Ltd., etc.). However, compared with the processing speed of other c...
