Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to photographic couplers that are capable of releasing photographically useful groups with controllable timing, and more particularly to photographic couplers that are highly reactive with oxidized forms of color developing agents and that are highly reactive with oxidized forms of color developing agents; The present invention relates to a halogenated color photographic light-sensitive material containing a photographic coupler which allows a reaction product produced by a coupling reaction to be easily washed out with alkali.

Various methods are known for releasing a group for photographic Kv using a compound used for photographic purposes, such as U.S. Pat.
11.062 and 1arr5j US Current Review No. 3.2
No. 27,554 discloses the release of an inhibitory agent or dye from the coupling site of a photographic coupler by reaction of a photographic coupler with an oxidized color developing agent.

U.S. Pat. No. 113.705,801 to Halts also discloses photographic couplers that release a bleach inhibitor from the coupling site after reaction of the coupler and oxidized color i1 with a dye.

The methods disclosed in the prior art and the compounds used all belong to the system in which photographically useful groups are directly released from these compounds.

However, such 72 direct release methods do not allow for the speeding up, slowing down, or control of the release of the photographically useful groups described above in relation to the various reactions occurring within the photographic element with other materials. or when an adjustment is required to move a photographically useful group a predetermined distance in order to achieve the desired effect at a predetermined constituent layer or location within a photographic element. , that adjustment is extraordinary KFIim.

Therefore, in order to improve this using conventional techniques, it is necessary to select components that release photographically useful groups, and also to consider means for bonding photographically useful groups to such components. It is important to consider this from a wide range of viewpoints, such as not only the selection of the photographically useful group itself but also the selection of the photographically useful group itself. This is inconsistent with the purpose and effect expected of a group that is useful for the purpose of use, and as a result, it results in a loss of freedom in selecting a compound for a given purpose.

On the other hand, more recently methods have been disclosed for indirectly releasing groups for photographic vcTi. These methods are described, for example, in U.S. Pat. , reacts with the oxidized form of the color developing agent,
In the IIIR step, the timing group with the photographically useful group is released, and then, as the Z-th step, the timing group undergoes an intramolecular aphrodisiac substitution reaction to release the final target, the photographically useful group. For example, Jikai ll54-1149
As described in No. 46, the timing group performs an electron transfer reaction along the conjugated chain as a step, releasing the final target photographically useful group, thereby producing a photographically useful material. In order to control many parameters such as temporal adjustment of effects by useful groups or distance SS* adjustment, adjustment can be made over a wide range H.

In this way, compounds in which a photographically useful group is substituted with the coupling position KW of a photographic coupler via a timing group are photographically useful because the appearance of the photographic action and effect due to the photographic K11i' group can be controlled. These compounds are extremely advantageous in terms of sensitive material design than compounds in which a group is directly substituted at the coupling position of a photographic coupler. Because the dye, which is an insoluble product, is uniformly formed and remains in the photographic element, it is used, for example, in a coupler-containing layer of different hues in a photographic light-sensitive material that utilizes a uniform non-diffusive dye. It has the serious disadvantage of causing color turbidity, which is unfavorable in terms of color reproduction.It is also applicable to photographic systems that diffusely transfer the dye image produced by the reaction with the oxidized product of the color developing agent. It also has the disadvantage that it is impossible.

Compounds are disclosed as components of photographic couplers which, upon reaction with oxidized forms of color developing agents, such as carbonyl carbonyl compounds, yield colorless reaction products. However, although these compounds are advantageous because they do not have the problem of color turbidity in photosensitive materials as mentioned above, they have low reactivity with the oxidized form of the color developing agent, and furthermore, the storage stability of the compounds is poor. It had the following drawbacks and was impractical.

Therefore, it is an object of the present invention to provide a halogenated compound containing a photographic coupler that has high coupling reactivity with the oxidized form of a color developing agent and is capable of releasing a photographically useful group at a time when it can be articulated. The purpose of the present invention is to provide a silver color photographic material.

The object of lI2 of the present invention is to provide a silver halide color photographic light-sensitive material in which a reaction product formed by a cutting reaction with an oxidized color developing agent has good flowability.

It is an object of the present invention to provide a silver halide color photographic light-sensitive material that does not cause color turbidity after being treated with IIs even when used in combination with copying and backing layer couplers having different hues.

A further object of the present invention is to provide a silver halide color photographic light-sensitive material having good storage stability over time.

Other objects of the invention will become self-evident from the description below.

The present inventors have conducted extensive research on the above, and have developed a silver halide color photographic light-sensitive material having at least one light-sensitive silver halide emulsion layer on a focusing support. Alternatively, the above object can be achieved by a silver halide color photographic light-sensitive material containing a non-photosensitive hydrophilic colloid llK compound represented by the following general formula.

Mu-TIM! -2 Here, mu is released from the compound represented by the above general formula after reaction with the oxidized color developing agent and transferred to the reaction 1J.

Furthermore, in the case of cyan couplers, phenolic compounds, naphfluor compounds, etc. can be used.In the present invention, any coupler residue can be used. Since the reactive product formed when reacting with the oxidized product of the color forming @II main agent must be soluble in alkali, such properties [K to impart to the above-mentioned reactive product] At least one molecule of the coupler residue or the oxidized color-imaging agent must have an alkali-soluble group.

Alternatively, an alkali-soluble group may be introduced into the oxidized product of the color member image, or an alkali-soluble group may be introduced into both. In the present invention, it is preferable to introduce an alkali-soluble group into the coupler residue.

5) and (16). In addition, samples (17) and (18) were obtained by injecting the comparative compounds 1 and 2) into the oil component of the third layer of sample (14).

Incidentally, the degree of addition of the image suppressant-releasing compound was adjusted so that ro (gamma of the edge-sensitive layer) was approximately 1.

Example 1 Samples (14) to (18) obtained in this manner were exposed uniformly to red light with a given amount of dust light so that the red density was 2.0. The development process was carried out in the same manner as above, and the results of the interimage effect on the #sensitive layer are shown in Table WI4 below.

The interimage effect on the red-sensitive layer was calculated as follows. That is, the red-sensitive layer is originally uniformly exposed so that D=2.0, but due to the interimage effect, the development of the red-sensitive layer is suppressed depending on the density developed with increased green sensitivity, resulting in a red ft, 8 The degree is expressed as a decreasing rate. Acupuncture Light I! The red light density when degree II is maximum is Dl
Then, inter2, () can be done. That is, it means that the larger this value is, the stronger the interimage effect is and the color reproducibility is improved.

(Table 4) In the upper layer - 4 clothes, 1.1. This means the Eμ interimage effect.

From the above IC table, samples (15) and (16) containing the compound related to the present invention are different from the samples (15) and (16) containing the comparative compound (sample (18) containing Bl, as well as the sample containing Comparison Zengonbutsu). It can be seen that the inter-image effect is clearly stronger than that of 17), and that Shikotanba's character is more favorable.lC0 agent Sakae Tsune ＾美 Continuing from page 1 0 Author: Hiroshi Sugita 1 Sakuracho, Hino City Konishiroku Photo Industry Co., Ltd.
