It accounts for at least 50% of the projected area. Here, tabular silver halide grains (tabular grains) are a general term for silver halide grains having one twin plane or two or more parallel twin planes. The twin plane is the (1 1 1) plane when ions at all lattice points on both sides of the (1 1 1) plane are in a mirror image relationship. These tabular grains have a triangular, hexagonal or rounded circular shape when the grains are viewed from above, with the triangular being triangular and the hexagonal being hexagonal. A square or circular shape has circular outer surfaces parallel to each other. In the present invention, the average aspect ratio of the tabular grains refers to the tabular grains having a grain thickness of less than 0.5 m and a grain diameter of 0.3 ra or more. It is the average of the values (aspect ratio) divided by. To measure the thickness of the particles, a metal was deposited from an oblique direction of the particles together with a reference lattice, the length of the shadow was measured on an electron micrograph, and the length of the shadow of the reference lattice was measured. This can be easily done by calculating with reference.

ハロゲン化銀粒子の熟成を促進するためには、 ハロゲン化 銀溶剤が有用である。 例えば熟成を促進するのに過剰量のハ ロゲンイオンを反応器中に存在せしめることが知られている。 それ故、 ハロゲン化物水溶液を反応器中に導入するだけで熟 成を促進し得ることは明らかである。 また、 他の熟成剤を用 いることもできる。 これらの熟成剤は銀塩およびハロゲン化 物塩を添加する前に反応器中の分散媒中に全量を配合してお く ことができる し、 また 1もしく は 2以上のハロゲン化物塩、 銀塩または解膠剤を加えると共に反応器中に導入することも できる。 熟成剤をハ口ゲン化物塩および銀塩添加段階で独立 して導入することもできる。 前記ハロゲンイオン以外の熟成剤と しては、 アンモニア、 ァ ミ ン化合物、 チオシァネー ト塩、 例えばアルカ リ金属チォ シァネー ト塩、 特にナ ト リ ゥム及び力 リ ゥムチォシァネー ト 塩、 並びにアンモニゥムチオシァネー ト塩を用いることがで きる。 チオシァネー ト熟成剤を用いることは米国特許第 2, 222, 264号、 同 2, 448, 534号および同 3, 3 20, 069号に教示されている。 また米国特許第 3, 27 1, 1 57号、 同 3, 574, 628号、 および同 3, 73 7, 3 1 3号に記載されるような周知のチォエーテル熟成剤 を用いることもできる。 あるいは特開昭 53— 82408号、 同 53— 1443 1 9号に開示されているようなチオン化合 物を用いることもできる。 A silver halide solvent is useful for accelerating ripening of silver halide grains. For example, it is known to have excess halogen ions present in the reactor to promote ripening. Therefore, it is clear that ripening can be promoted simply by introducing an aqueous halide solution into the reactor. Also, other ripening agents can be used. These ripening agents can be incorporated in their entirety in the dispersion medium in the reactor before adding the silver salt and the halide salt, or one or more halide salts, silver salts or silver salts can be added. A salt or peptizer may be added and introduced into the reactor. The ripening agent can also be introduced independently at the stage of adding the haematogenide salt and the silver salt. As the ripening agent other than the above-mentioned halogen ions, ammonia, amine compounds, thiosinates, for example, alkali metal thiosinates, particularly sodium and potassium sulphate salts, and ammonium thiosinates Agate salts can be used. The use of thiocyanate ripening agents is taught in U.S. Pat. Nos. 2,222,264, 2,448,534 and 3,320,069. Also, well-known thioether ripening agents as described in U.S. Pat. Nos. 3,271,157, 3,574,628 and 3,737,313 can be used. Alternatively, thione compounds as disclosed in JP-A-53-82408 and JP-A-53-144319 can be used.

Such a compound may be initially present in the reaction vessel, or may be added together with one or more salts according to a conventional method. U.S. Pat. Nos. 2,448,060, 2,628,167, 3,737,313, 3,772,031, and Research Disclosure (hereinafter abbreviated as RD) ), Volume 134, June 1975, 13452, copper, iridium, lead, bismuth, cadmium, zinc, (potential lucogen compounds such as sulfur, selenium and tellurium), The properties of silver halide grains can be controlled by the presence of compounds such as gold and compounds of Group VH1 noble metals during the formation of silver halide precipitates. It is preferred that the silver halide emulsion of the present invention is subjected to reduction sensitization during grain formation, after grain formation and before chemical sensitization other than reduction sensitization, during chemical sensitization, or after chemical sensitization.
ここで還元増感とはハロゲン化銀乳剤に還元増感剤を添加 する方法、 銀熟成と呼ばれる pA g 1〜 7の低 pA g の雰囲気で ハロゲン化銀粒子を成長させるあるいは熟成させる方法、 高 pH熟成と呼ばれる pE 8〜 1 1の高 pBの雰囲気で成長させるあ るいは熟成させる方法のいずれかを選ぶことができる。 また これらのうち 2つ以上の方法を併用することもできる。  Here, reduction sensitization refers to a method in which a reduction sensitizer is added to a silver halide emulsion, a method in which silver halide grains are grown or ripened in an atmosphere having a low pAg of pAg 1 to 7, which is called silver ripening. Either growth or ripening in a high pB atmosphere with a pE of 8 to 11 called pH ripening can be selected. Also, two or more of these methods can be used in combination.
上記の還元增感剤を添加する方法は還元増感のレベルを微 妙に調節できる点で夫々好ま しい方法である。  The above method of adding a reducing sensitizer is a preferable method because the level of reduction sensitization can be finely adjusted.

For the reduction sensation used in the present invention, these known reduction sensitizers can be selected and used, and two or more compounds can be used in combination. Preferred compounds as reduction sensitizers used in the present invention are stannous chloride, thiourea dioxide, dimethylamborane, ascorbic acid and derivatives thereof. The addition amount of the reduction sensitizer in the present invention it is necessary to be selected depending on the emulsion manufacturing conditions, a preferable range of 1 0 _7 ~ 1 0 one 3 moles per mole of silver halide equivalent Ri.

It is good to add to the reaction vessel in advance The method of adding at an appropriate time during the growth of the silver halide grains is preferred. Alternatively, a reducing sensitizer may be added in advance to an aqueous solution of a water-soluble silver salt or a water-soluble alkali halide, and these aqueous solutions may be used to precipitate silver halide particles. It is also preferable to add the solution of the reducing sensitizer in several portions as the silver halide grains grow, or to continuously add the solution for a long time.
本発明に用いられるハロゲン化銀乳剤には例えば、 欧州特 許第 96, 727 B 1号、 同 64, 4 1 2 B 1号に開示され ているような粒子に丸みをもたらす処理、 あるいは西独特許 第 2, 306, 447 C 2号、 特開昭 60 - 22 1 320号 に開示されているような表面の改質を行ってもよい。  The silver halide emulsion used in the present invention may be, for example, a treatment for imparting roundness to grains as disclosed in European Patent Nos. 96,727 B1 and 64,412 B1 or a West German patent. The surface may be modified as disclosed in Japanese Patent No. 2,306,447 C2 and JP-A-60-221320.
本発明におけるハロゲン化銀乳剤では、 その粒子表面は平 坦な構造であることが一般的であるが、 意図して凹凸を形成 することは場合によって好ま しい。 特開昭 58— 1 0653 2号、 特開昭 60— 22 1 320号に記載されている結晶の 一部分、 例えば頂点あるいは面の中央に穴があけられた粒子、 あるいは米国特許第 4, 643, 966号に記載されている ラッフル粒子がその例である。  In the silver halide emulsion of the present invention, the grain surface generally has a flat structure, but intentionally forming irregularities is sometimes preferable. A portion of the crystal described in JP-A-58-1 06532 and JP-A-60-221320, for example, a particle having a hole at the vertex or the center of the surface, or US Pat. No. 4,643, Raffle particles described in 966 are an example.

Such dislocations can include dislocations introduced linearly in a particular direction of the crystallographic orientation of the grain, distorted dislocations, dislocations introduced throughout the grain, or introduced only in a particular part of the grain, For example, it can be selected from dislocations introduced only in the fringe portion of the particle. It is well known that a dislocation is a displacement (displacement) of a series of atomic arrangements in the crystal lattice, and its general definition is, for example, Shuji Suzuki, Introduction to Dislocation Theory, Agnesha, 1968, p. Specified on 24-31.

(Electron Microscopy of Thin Crystals, P 169-18.8, Butterworts, London, 1965).

Eng., 11, 57 (1967), Shiozawa (Nissha, 16 (171), 3_ 5_, 2 1 3 (1 972)).
ハロゲン化銀粒子の電子顕微鏡観察用試料の作成および観 察は塩沢の文献 (日写誌, 34, 16 ( 1 97 1 ) に記載さ れている方法により実施する。 ·  Preparation and observation of silver halide grains for electron microscopic observation are performed by the method described in Shiozawa's literature (Nissha Journal, 34, 16 (1971)).
電子顕微鏡でハロゲン化銀粒子を観察すると、 転位線以外 に、 等傾角干渉縞、 積層欠陥、 電子顕微鏡観察時の電子線照 射によつて生ずるプリ ン トアウ ト銀、 モアレ像などが見られ るが、 これらの像はいずれも一般的に知られているものであ これらの像のコン トラス ト生成の原因ならびに同定法につ いては、 一般的には H i r s c hら (前出) により、 また、 ハロゲン化銀粒子については H o m i 1 t o n (前出) によ り報告されており、 転位線像とは、 識別することが可能であ 転位線密度測定法及び転位線密度の粒子間分布測定法 転位線密度とは、 1粒子中に存在する転位線の本数である とする。 その測定は次のように行う。 入射電子に対して傾斜 角度を変えた一連の粒子写真を 1個 1個の粒子について撮影 し、 転位線の存在を確認する。 この時、 転位線の本数を数え られるものについてはその本数を数える。 転位線が密集して 存在し 1粒子当りの転位線の本数を数えることが出来ない場 合は多数の転位線が存在すると数える。 転位線密度の粒子間 分布は、 2 0 0個以上の粒子、 より好ま しく は 3 0 0個以上 の粒子について転位線密度を測定し、 その度数分布を作成す ることにより求める。 When observing silver halide grains with an electron microscope, in addition to dislocation lines, equitilt interference fringes, stacking faults, printout silver, moiré images, etc. generated by electron beam irradiation during electron microscopic observation can be seen. However, all of these images are generally known. The cause of the contrast generation of these images and the identification method are generally described by Hirsch et al. For silver halide grains, see Homi 1 ton (supra). Dislocation line images can be distinguished Dislocation line density measurement method and method for measuring dislocation line density distribution between particles Dislocation line density is the number of dislocation lines present in one particle It is assumed that The measurement is performed as follows. A series of particle photographs with different tilt angles with respect to the incident electrons are taken for each particle to confirm the existence of dislocation lines. At this time, if the number of dislocation lines can be counted, the number is also counted. When dislocation lines exist in a dense manner and the number of dislocation lines per particle cannot be counted, it is counted that there are many dislocation lines. The distribution of dislocation line densities between particles is determined by measuring dislocation line densities of 200 or more particles, more preferably 300 or more particles, and creating a frequency distribution.

Other silver salts, for example, silver rhodan, silver sulfide, silver selenide, silver carbonate, silver phosphate, and organic acid silver may be contained as separate grains or as a part of silver halide grains. When rapid development / desilvering (bleaching, fixing and bleach-fixing) processes are desired, silver halide grains containing a large amount of silver chloride are preferred. In order to appropriately suppress the development, it is preferable to contain silver iodide. The preferred silver iodide content depends on the intended light-sensitive material. For example, 0.1 to 15 mol% is preferred for X-ray sensitive materials, and 0.1 to 5 mol% is preferred for graphic arts and microsensitive materials. Silver iodide content. In the case of a photographic light-sensitive material represented by a color negative, a silver halide containing 1 to 30 mol% of silver iodide is preferably used, more preferably 5 to 20 mol%, particularly preferably. For silver halide, silver halide containing 8 to 15 mol% of silver iodide can be used. It is. It is preferable that silver iodobromide grains further contain silver chloride because lattice strain is reduced. The silver halide emulsion according to the present invention preferably has a distribution or structure with respect to the halogen composition in the grains. Typical examples thereof include, for example, Japanese Patent Publication No. 3-13162, Japanese Patent Application Laid-Open No. 61-215540, Japanese Patent Application Laid-Open No. 60-222845, Japanese Patent Application No. 60-143331, and Japanese Patent Application No. 61-75337 is a core-shell type or double-structure type particle having a different halogen composition between the inside of the particle and the surface layer. Further, instead of a mere double structure type particle, a triple structure type particle as disclosed in Japanese Patent Application Laid-Open No. 60-222484, or a multilayer structure type particle having more than that, a core-surprising double The grains may have a structure in which silver halides having different compositions are thinly applied to the surfaces of the grains having the structure.
本発明に係るハロゲン化銀粒子として内部に構造を有する 粒子には、 上述のような包み込む構造だけでなく、 いわゆる 接合構造を有する粒子も挙げられる。 これらの例は例えば、 特開昭 59 - 1 33540号、 特開昭 58 - 1 08526号、 欧州特許第 1 99, 290 A 2号、 特開昭 58 - 24772 号、 特開昭 59— 1 6254号に開示されている。 接合させ る結晶はホス トとなる結晶と異なる組成をもってホス ト結晶 のエッジやコーナー部、 あるいは面部に接合して生成させる ことができる。 このような接合構造を有する結晶には、 ホス ト結晶がハロゲン組成に関して均—であるものあるいはコア 一シェル型の構造を有するもののいずれをもが使用され得る。 上記接合構造の場合にはハロゲン化銀同士の組み合せは当 然可能であるが、 岩塩構造でない銀塩化合物、 例えば、 ロダ ン銀、 炭酸銀をハロゲン化銀と組み合せた接合構造をとるこ ともできる。 また酸化鉛のような非銀塩化合物も接合構造が 可能であれば用いてもよい。 The grains having a structure inside as the silver halide grains according to the present invention include not only the above-described wrapping structure but also grains having a so-called junction structure. Examples of these are disclosed, for example, in JP-A-59-133540, JP-A-58-108526, European Patent No. 199,290 A2, JP-A-58-24772, and JP-A-59-16254. Issue. The host crystal has a composition different from that of the host crystal. It can be generated by bonding to the edges, corners, or faces of the surface. As the crystal having such a junction structure, either a crystal having a uniform host crystal with respect to the halogen composition or a crystal having a core-shell structure can be used. In the case of the above joint structure, the combination of silver halides is naturally possible, but a joint structure in which a silver salt compound having no rock salt structure, for example, rhodium silver or silver carbonate is combined with silver halide can also be used. . Further, a non-silver salt compound such as lead oxide may be used as long as the bonding structure is possible.
これらの構造を有する沃臭化銀等の粒子の場合、 コア部が シェル部より も沃化銀含有量を高く させることは好ま しい態 様である。 逆にコア部の沃化銀含有量が低く、 シェル部の沃 化銀含有量が高い粒子が好ま しい場合もある。 同様に前記接 合構造を有する粒子についてもホス ト結晶の沃化銀含有率が 高く、 接合結晶の沃化銀含有率が相対的に低い粒子であって も、 またはその逆の関係を有する粒子であってもよい。 また、 これらの構造を有する粒子のハロゲン組成の異なる境界部分 は、 明確な境界であっても、 不明確な境界であってもよい。 また粒子に積極的に連続的なハロゲン組成の変化をつけたも のも好ま しい態様である。  In the case of grains such as silver iodobromide having such a structure, it is preferable that the core portion has a higher silver iodide content than the shell portion. Conversely, in some cases, grains having a low silver iodide content in the core portion and a high silver iodide content in the shell portion are preferred. Similarly, the grain having the above-mentioned bonding structure may be a grain having a high silver iodide content of the host crystal and a relatively low silver iodide content of the bonding crystal, or a grain having the opposite relation. It may be. In addition, the boundary portions of the grains having these structures having different halogen compositions may be clear boundaries or unclear boundaries. Also, a preferred embodiment is one in which a continuous change in the halogen composition is positively applied to the grains.
2つ以上のハロゲン化銀が混晶として、 あるいは構造をも つて存在するハロゲン化銀粒子の場合には、 粒子間のハロゲ ン組成分布を制御することが重要である。 粒子間のハロゲン 組成分布の測定法に関しては特開昭 6 0 - 2 5 4 0 3 2号に 記載されている。 粒子間のハロゲン分布が均一であることは 望ま しい特性である。 特に変動係数 2 0 %以下の均一性の高 い乳剤は好ま しい。 別の好ま しい形態は粒子サイズとハロゲ ン組成に相関がある乳剤である。 例と して大サイズ粒子ほど ョー ド含量が高く、 一方、 小サイズ粒子ほどョー ド含量が低 いような相関がある場合である。 目的により逆の相関、 他の ハロゲン組成での相関を選ぶことができる。 この目的のため に、 組成の異なる 2つ以上の乳剤を混合させることが好ま し い。 In the case of silver halide grains in which two or more silver halides exist as mixed crystals or have a structure, it is important to control the halogen composition distribution between grains. The method for measuring the halogen composition distribution between grains is described in JP-A-60-254302. Halogen distribution between grains is uniform This is a desirable characteristic. In particular, highly uniform emulsions having a coefficient of variation of 20% or less are preferred. Another preferred form is an emulsion which correlates grain size with halogen composition. For example, there is a correlation in which large particles have a higher eode content, while small particles have a lower eode content. Depending on the purpose, you can select the opposite correlation, or the correlation for other halogen compositions. For this purpose, it is preferable to mix two or more emulsions having different compositions.
本発明に係るハ口ゲン化銀粒子の表面近傍のハロゲン組成 を制御することは重要である。 粒子表面近傍の沃化銀含量を 高くすること、 あるいは塩化銀含量を高くすることは、 色素 の吸着性や現像速度を変化させるので目的に応じて選択され て行われる。 粒子表面近傍のハ口ゲン組成を変化させる場合 に、 粒子全体を包み込む構造でも、 粒子の一部分にのみ付着 させる構造のどちらも選ぶことができる。 例えば平板粒子の 主平面と側面の一方のハ口ゲン組成を変化させた状態が選ば れ 。  It is important to control the halogen composition near the surface of the silver halide grains according to the present invention. Increasing the silver iodide content in the vicinity of the grain surface or increasing the silver chloride content is selected according to the purpose because it changes the adsorptivity of the dye and the developing speed. When changing the composition of the hagogen near the particle surface, either a structure that wraps the entire particle or a structure that adheres only to a part of the particle can be selected. For example, a state where the composition of one of the main plane and the side of the tabular grain is changed is selected.

本発明のテルル增感に用いられるテルル増感剤は、 ハロゲ ン化銀乳剤粒子表面又は粒子内部に、 増感核となると推定さ れるテルル化銀を生成せしめる化合物である。  The tellurium sensitizer used in the tellurium sensitization of the present invention is a compound that forms silver telluride which is presumed to be a sensitizing nucleus on the surface of silver halide emulsion grains or inside the grains.
ハロゲン化銀乳剤中のテルル化銀生成速度については以下 の試験ができる。  The following test can be performed for the formation rate of silver telluride in a silver halide emulsion.
多量添加 (例えば、 1 X 1 0一3モル Zモル A g ) すると、 生成したテルル化銀が可視域に吸収をもつ。 従って、 ィォ ゥ増感剤について、 E.

The amount of silver sulfide formed in a silver halide emulsion was determined from the infinite reflectivity of the emulsion in the visible region (520 nm) using the Kubea-Munk equation. twenty five
を甩いて求めたのと同様の方法で、 相対的なテルル化銀生成 速度を簡便に求めることができる。 また、 この反応は、 見か け上一次反応に近いので、 擬一次反応速度定数も求めること ができる。 The relative silver telluride formation rate can be easily obtained in the same manner as that obtained by using the above method. In addition, since this reaction is apparently close to a first-order reaction, a pseudo-first-order reaction rate constant can also be obtained.
擬一次反応速度定数の求め方を以下に述べる。  The method for obtaining the pseudo first-order reaction rate constant will be described below.
平均粒子径 0. 5 mの臭化銀八面体乳剤 ( 1 乳剤中に A g B r 0. 75モル、 ゼラチン 80 gを含有) を  An octahedral silver bromide emulsion with an average particle size of 0.5 m (0.75 mol of AgBr and 80 g of gelatin per emulsion)
p H = 6. 3, p A g = 8. 3に保ちつつ 50 °Cに保温し、 有機溶剤 (例えばメ タノール) に溶解したテルル化合物を 1 X 10 Jモル/モル A g添加する。 積分球をもつ分光光度 計で 1 en厚みのセルに乳剤を入れ、 ブラ ンクの乳剤を参照に して、 520 nraでの反射率 (R) を時間を追って測定してい く。 反射率を Kubel -Munkの式 ( 1一 R) 2 Z2 Rに代入し その値が 0. 0 1 になるまでの時間から擬一次反応速度定数 k (min-1) を求める。 テルル化銀を生成しなければ、 常に、 R = 1のため Kubelka-Miinkの値はテルル化合物のない時と同 じで 0のままである。 このテス ト法と全く 同一条件での見か けの一次反応速度定数 kが 1 X 1 CT。〜: L x l O^ min_1の 化合物が好ま しい。 Keep the temperature at 50 ° C while maintaining pH = 6.3 and pAg = 8.3, and add 1 x 10 Jmol / mol Ag of tellurium compound dissolved in an organic solvent (eg, methanol). Using a spectrophotometer with an integrating sphere, place the emulsion in a cell with a thickness of 1 en and measure the reflectance (R) at 520 nra over time with reference to the blank emulsion. Its value by substituting reflectivity equation (1 one R) 2 Z2 R of Kubel -Munk seek time pseudo-first order reaction rate constant from k until the 0. 0 1 (min -1). If silver telluride is not formed, the value of Kubelka-Miink always remains 0 because R = 1 as in the absence of tellurium compounds. The first-order reaction rate constant k found under exactly the same conditions as this test method is 1 X 1 CT. ~: L xl O ^ min _1 compounds are preferred.
本テス ト法による本発明のテルル增感剤の擬一次反応定数 を例示すると以下の通りであった。  The pseudo-first-order reaction constants of the tellurium sensitizer of the present invention according to the test method are as follows.

また、 可視域の吸収が検出しにく いより少量の添加量域で は、 生成したテルル化銀を未反応テルル増感剤から分離し定 量できる。 例えば、 ハロゲン塩水溶液や、 水溶性メルカプト 化合物の水溶液などへの浸漬で分離したあと、 原子吸光法な どにより、 微量の T eを定量分析する。 この反応速度は、 化 合物の種類は勿論のこと被検乳剤のハロゲン化銀組成、 試験 する温度、 p A gや p Hなどで数ケタの範囲で大きく変動す る。 本発明で好ましく用いられるテルル増感剤は、 用いよう とするハロゲン組成、 晶癖を有する具体的なハロゲン化銀乳 剤に対してテルル化銀を生成しうる化合物である。 総括的に 言えば、 ハロゲン化銀乳剤に対して、 温度 40〜95で、 p H3〜 10、 または p A g 6〜l lのいずれかの範囲で、 テルル化銀を生成しうる化合物が本発明に対して好ま しく用 いられ、 この範囲で、 上記テス ト法による擬一次反応速度定 数 kが、 1 X 10 _7〜: L X 10 _丄 min-1の範囲に入る化合物 がテルル增感剤としてより好ま しい。 In addition, in the addition amount range where the absorption in the visible region is difficult to detect, the generated silver telluride can be separated and quantified from the unreacted tellurium sensitizer. For example, after separation by immersion in an aqueous solution of a halogen salt or an aqueous solution of a water-soluble mercapto compound, a trace amount of Te is quantitatively analyzed by an atomic absorption method or the like. This reaction rate varies greatly within several digits depending on the silver halide composition of the emulsion to be tested, the temperature to be tested, pAg and pH, as well as the type of compound.
