[0002]

2. Description of the Related Art In recent years, demands on performance of silver halide color photographic light-sensitive materials have become increasingly severe, and high sensitivity,
There is a higher demand for photographic performance such as graininess and processing stability.

The relative reaction rates of the two magenta couplers having different reaction rates used in the present invention are described in J. Am. Text
er's method (J. Texter, J. Photogr.
Sci. , 36, 14 (1988)), that is, a relative reaction can be determined by a method utilizing a competitive reaction using citrazic acid, which is a water-soluble external coupler.

Specifically, each magenta coupler of interest is dissolved in ethyl acetate and OIL-1 (described later), and the resulting dispersion is emulsified and dispersed in an aqueous solution containing gelatin. A coating solution is prepared by adding a general photographic additive such as a coating agent, coated on a triacetyl cellulose film support by a conventional method, and dried to prepare a single emulsion layer sample for each magenta coupler.

Each of the single emulsion samples was exposed to a fixed wedge, and then subjected to a development process described below and a development process using a color developer obtained by adding 2.0 g / l of citrazic acid to the color developer. Then, for each of the characteristic curves of the two obtained color images, a density difference ΔD between the density of Dmin + 0.2 and the density obtained when an exposure amount that is 10 times the exposure amount that provides the density is obtained. For each coupler, t = ΔD
/ ΔD (citrazinic acid addition treatment) can be determined to relatively determine the coupling speed. (The larger t is,
Slow reactivity. In the present invention, the expression that the 2-equivalent pyrazolone-type magenta coupler is solely contained refers to a dye image-forming coupler that contains only one type of coupler that does not have functions such as development suppression, color correction, and development processing adjustment. That is, the same layer may contain a coupler having functions such as development suppression, color correction, and development processing adjustment.

It has been found that the use of magenta couplers having the same coupling speed in the medium- and high-speed layers is preferable in terms of stability of gradation, particularly stability against fluctuations in storage over time and fluctuations in development processing. .

You can ask. If the amount of magnetization per unit area of the transparent magnetic layer is smaller than 3 × 10 ⁻² emu, input / output of magnetic recording is hindered.

It is also preferable to form a binder by aqueous coating using an aqueous emulsion resin without using an organic solvent. Further, it is necessary to adjust physical properties of the binder by curing with a curing agent, heat curing, electron beam curing, or the like. In particular, curing by adding a polyisocyanate-type curing agent is preferable.

It is necessary to add an abrasive to the magnetic recording layer in order to prevent clogging of the magnetic head, and it is preferable to add nonmagnetic metal oxide particles, particularly alumina fine particles.

Is generally preferred because of its high conductivity, and the latter is particularly preferred because it does not give fog to the silver halide emulsion.

As the binder for the conductive layer and the undercoat layer, the same binder as that for the magnetic recording layer can be used.

It is preferable to coat a higher fatty acid ester, a higher fatty acid amide, a polyorganosiloxane, a liquid paraffin, a wax, etc. on the magnetic recording layer as a sliding layer.

<< Evaluation of Photographic Properties of Sensitive Material Samples >> These samples 101 to 110 were exposed to light according to the following performance evaluations, subjected to development processing according to the processing steps described below, and Was evaluated.

<< Sensitivity >> A wedge exposure using white light is applied, the following development processing is performed, and the reciprocal of the exposure amount that gives the minimum density of +0.2 from the characteristic curve of the magenta color image is determined as the sensitivity. Table 2 shows the relative sensitivities when the sensitivity was set to 100.

<< Granularity >> The granularity is defined as the relative value (RMS value) of the standard deviation (RMS value) of the fluctuation of the density value generated when the density portion of Dmin + 0.5 is scanned by a microdensitometer having an opening scanning area of 250 μm ^2. The relative value when the magenta color image of the sample 101 was taken as 100) was obtained and is shown in Table 2 as relative granularity. The smaller this value is, the more excellent the graininess is.

<< Processing Stability >> After preparing three copies of each of Samples 101 to 110 and exposing them to wedges with white light, the color developing times were changed to 2 minutes and 45 seconds, 3 minutes and 15 seconds, and 3 minutes and 45 seconds, respectively. Processing was performed.

For the samples 101 to 110, the change in sensitivity due to the change in the color development time was determined from the characteristic curve of the magenta color image by the relative sensitivity (from the characteristic curve of each color development time of each sample, the exposure amount giving an optical density of fog +0.3 was obtained. Of each sample was evaluated as a relative value when the value obtained by treating each sample for 3 minutes and 15 seconds was 100). Both 2 minutes 45 seconds and 3 minutes 45 seconds indicate that the closer the value is to 100, the better the processing stability.
