Problems solved by technology

In practice, however, such processing necessarily produces negative effects (other deterioration in image quality) such as deterioration of grain size, unnatural retouching, and the quality of photographs obtained with such improved photosensitive materials is not as good as with high-sharp photosensitive materials containing colored couplers The quality of the photo taken

Embodiment 1

[0166] The color photosensitive material is prepared according to the following steps.

[0167] Comparative Sample 001, which is a multilayer color photosensitive material, was prepared by coating an undercoated cellulose triacetate film support with a plurality of layers having the composition described below.

[0168] (Composition of photosensitive layer)

[0169] The main materials used in the layers are divided into the following categories:

[0170] ExC: cyan coupler; ExS: spectral sensitizing dye; UV: ultraviolet absorber; ExM: magenta coupler; HBS: high boiling point organic solvent; ExY: yellow coupler; H: gelatin hardener (in the description below, Specific compounds are represented by symbols followed by numbers. The general chemical formulas of these compounds will be represented as follows.)

[0171] The number corresponding to each component indicates the coating weight (g / m 2 ). The coating amount of silver halide is calculated by silver content. The coating...

Abstract

A silver halide color negative photographic lightsensitive material comprises, on a support, at least one blue-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one red-sensitive silver halide emulsion layer. The total coating amount of colored couplers in the lightsensitive material is less than 0.05 mMol / m2. The lightsensitive material contains at least one spectrally sensitized silver halide emulsion and a compound capable of absorbing light within the spectrally sensitizing region of the spectrally sensitized silver halide emulsion, and capable of reducing the sensitivity of the spectrally sensitized silver halide emulsion by at least 0.05 LogE.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from prior Japanese Patent Application No. 2001-119951 filed on April 18, 2001, the entire contents of which are incorporated herein by reference. field of invention [0003] This invention relates to a color negative-working photosensitive material substantially free of color-masking couplers. It is an object of the present invention to provide a photosensitive material suitable for digital scanning because it is substantially free of color-masking couplers. The present invention provides, inter alia, a photosensitive material with improved sharpness, which is a disadvantage of photosensitive materials containing no color coupler. Background of the invention [0004] With the recent advancement and popularization of digital technology characterized by personal computers, the advantages and necessity of converting images into digital files have become increasingly promi...
