Description

 Details ^ Silver halide photographic material

 The present invention relates to a silver halide color photographic light-sensitive material. More specifically, the present invention relates to a silver halide color photographic material having excellent bleaching properties, reduced sting, improved white background, and both of these performances and an expanded color reproduction range. The present invention relates to a color photographic material. Background art

 In recent years, in the photo processing service industry, the development of high-quality silver halide photographic materials with rapid processing suitability has been desired as part of improving services to users and as a means of improving productivity. . In response to this demand, a silver halide photosensitive material containing a silver halide emulsion with a high silver chloride content (hereinafter also referred to as a high silver chloride print material) has been developed with a color development time of 45 seconds. Rapid processing is usually performed, in which the total processing time from the start of the development process to the completion of the drying process is about 4 minutes or less. However, when compared with the speed of other color image forming methods such as electrostatic transfer method, thermal transfer method, and ink jet method, the rapid development processing system for high silver chloride print materials still does not. It is hard to say that it is satisfactory swiftness, and ultra-rapid processing in which the total processing time from the start of development to the end of drying of the high silver chloride color print material is less than 1 minute is desired.

For this reason, various technical means for imparting ultra-rapid suitability to silver halide photographic materials have been studied in the art. For example, to improve suitability for ultra-rapid processing As means, the amount of organic material to be applied can be reduced by using a coupler with a high molecular extinction coefficient of a high-activity coupler or a color-forming dye to be formed, a coating amount of a hydrophilic binder can be reduced, and a silver halide emulsion with a high development speed The adoption of is being considered.

 However, rapid processing is often accompanied by a reduction in image quality, which is a major constraint, especially when achieving ultra-rapid processing. One of the declines in image quality associated with ultra-high speed is the decrease in whiteness of highlights. Factors of the decrease in whiteness include poor desilvering due to shortening of processing time, coloring of a white background portion of an image due to a residue in a silver halide photosensitive material. Furthermore, whiteness largely depends on the viewing light source dependence.

 However, in order to satisfy the strict requirements of the white background of a color print, it is necessary to devise a method of improving the white background other than suppressing the coloring and coloring of the white background. As one method for this, a method of applying a fluorescent whitening agent to a color print has been proposed. For example, a method has been proposed in which a fluorescent brightener is contained in a water-resistant resin layer constituting a reflective support (for example, see Patent Document 1). In this method, the reflective support contains a fluorescent whitening agent to absorb part of the ultraviolet energy and emit fluorescence in a short wavelength range, thereby improving the white background. If the energy is high, the reflectance near the center of gravity wavelength exceeds 100% and a high-brightness white background can be obtained, but when viewed under a light source with low UV energy, for example, under a white light, Has a problem that the fluorescent light is difficult to emit, and the apparent white background is significantly degraded.

The solutions to the defects associated with these ultra-rapid development processes have been vigorously studied in the industry, but are not yet sufficient. Accordingly, an object of the present invention is to provide a silver halide light-sensitive material having excellent bleaching properties, reduced sting, and improved white background, and having improved performance and expanded color reproduction range. To provide. (Patent Document 1)
