Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process for producing a pigment composition having very excellent dispersibility in a vehicle, wherein particles for color development have fine particle sizes and uniform particle diameters. And relates to a coloring composition using a color filter using the above pigment composition and a tinge color using the above coloring composition. In particular, the present invention relates to a method for preparing a pigment composition, which is used for color development. When the powder particles are dispersed in an ink such as a gravure ink or an offset ink or a vehicle of a coating, the pigment composition provides a coating having good light, degree = high color strength. The present invention also relates to a coloring composition for a color filter for preparing a color filter for use in a color liquid crystal display and a color image pickup tube element, and to a color filter formed using the above colored composition . [Prior Art] Some organic pigments, such as azo pigments, are synthesized by selecting appropriate reaction conditions to fine and uniform particles. For other organic pigments such as copper cerium pigment 5, the extremely fine and agglomerated particles produced in the synthesis can be increased and self-automated. For other money, a process called coloring, which is produced in the synthesis, and the size of the uneven particles are finely divided and homogenized at the time of post-processing. Right: ΐ2t green pigment has beautiful color and high color strength and It has a variety of properties such as resistance to purity and heat resistance and is used in the industrial field of coloring materials. Nicknames are generally large, and copper phthalocyanine pigments are doubled under ten pressures or supercharged, and there is or lacks 312XP/ SUMMARY OF THE INVENTION (Supplement) /95-08/95114255 ^ 200706604 In the case of a reagent such as ammonium molybdate or titanium tetrachloride, a reaction between phthalic anhydride or a derivative thereof, a source of urea and copper, or a phthalonitrile • Preparation of a reaction between (Phthalodinitrile) or a derivative thereof and an organic solvent such as an alkylbenzene, tri-chlorobenzene or a copper source in nitrobenzene. However, the synthesized indigo molecule is grown by continuous particles in its synthetic solvent. Therefore, only coarse particles and acicular particles having a major axis diameter of about 1 〇 to 2 〇〇//m are obtained. Therefore, as a coloring pigment for inks, paints, plastics, etc., the value is very low. And this indigo is called blister copper. Therefore, it is necessary to finely pulverize the crude copper indigo to obtain particles having high effectiveness in coloring, that is, particles having a particle diameter of about 0·01 to 〇5//m. As an industry for finely crushed crude copper indigo Methods, various methods are known. For example, a so-called solvent salt grinding method is known (see Jp-A-7-53889 and JP-A-5-43704) in which a small amount of a solvent such as diethylene glycol is added. To a mixture of blister copper indigo and sodium chloride, and vigorously kneading it by a ball mill, an attritor or a batch kneader to wet-grind the thus mixed mixture. In this method, it is washed with water. Sodium chloride and diethylene glycol are removed from the kneaded mixture, and then dried to obtain a copper indigo pigment having fine primary particles. However, there are some problems with the batch kneader, such as due to them. The batch form limits the scale of production, the quality changes between batches, the incorporation of impurities due to their open structure, the contamination of the work due to the generation of dust, and the need for large amounts of energy for finely divided organic pigments. and There is also a limit on the level of fine crushing. In addition, when the obtained copper eucalyptus pigment is dispersed in a printing ink such as gravure ink or offset ink or paint, 312XP/invention specification (supplement)/95-08/95114255 200706604 In the agent and using the obtained copper indigo pigment, it is always necessary to improve the gloss and coloring strength of the coated article. In the liquid crystal display, the liquid crystal layer sandwiched between the two polarizing plates controls the first one. The polarizing angle of the polarizing plate controls the amount of light transmitted through the second polarizing plate, thereby performing display. The main liquid crystal display device is a display using twisted nematic (TN) type liquid crystal. By providing color filter between the two polarizing plates The LCD enables the LCD display to display colors. In recent years, liquid helium has been shown to be used in televisions and monitors for personal computers. For this reason, there is a growing need for filters with high brightness and high contrast.

The color filter is composed of at least two thin strips of color filters of different colors arranged in parallel or on the surface of a transparent substrate such as a glass substrate, or fine filter and color patches arranged horizontally and vertically in a constant order. The color filter sheets are fine, i.e., from a few micrometers to hundreds of micrometers, and the filter color chips are systematically arranged in a predetermined array for each color. W ’ vacuum evaporation and splashing

However, in general, a color filter in which a pigment is dispersed generally has light scattering. In a color liquid crystal display device, a transparent electrode which is used to drive a liquid crystal is formed to form an orientation of a liquid crystal in a predetermined direction on a color filter. on. For the performance of the electrode and the oriented film, Tonga Yun I a 312XP / Invention Manual (supplement) / 95-08/95114255 7 200706604 Problem 'This is because the pigment disturbs the polarization angle controlled by the liquid crystal. That is, light leaks when light should be intercepted (〇FF state), and transmitted light when light should be transmitted (0N state). The problem at this time is that the brightness ratio of the display between the (four)-states is low (in order to achieve a high contrast (four) color filter, the pigment contained in the color filter sheet is finely processed. As a method of finely pulverizing the pigment, The solvent salt grinding method described above has been widely used in recent years. * The salt grinding method is a water-soluble organic solvent such as ethylene glycol, diethylene glycol or polyethylene in an inorganic salt such as sodium chloride or sodium sulfate and having a high viscosity. In the case where a diol is present, a method of finely pulverizing coarse pigment particles by mechanically grinding the particles with a kneader or the like. The solvent salt grinding method is effective for finely divided and homogenous pigment particles. However, in order to achieve improvement in contrast of the color former It is necessary to use a pigment having finer and more uniform particles than the pigment particles obtained by the conventional salt milling method. SUMMARY OF THE INVENTION An object of the present invention is to provide a method for preparing a pigment composition, which overcomes the conventional Problems with the batch kneading machine, such as the quality change of the production scale within the limit of t times, the mixing of the shellfish due to its open structure, and the generation of powder Dust and pollute the working environment.

For example, it is preferred to use a continuous kneader consisting of "Miracle KCK" as shown in Fig. 1. The continuous kneading machine 1G has a clad portion 2, a discharge portion 3, and a metering feeder portion 4 = a widened portion 1 It includes the basic structure of the horizontal knives 4±. 11 Concentric and slidable contact can be strong and shouted 11 and the screw feeder part 4 with the outer casing (4) receives the raw material inlet (1) doorway / Yu 攸e Shili The top surface of the casing 11. The drive shaft 121 (Fig. 7) externally fixed to the driving motor on the upstream side of the starting end of the auger 12 is concentric, the driving of the driving motor is transmitted via the transmission shaft 121, and the hunting wheel 12 is wound. The shaft of the shaft 121 rotates the medium: 1 ' so that the spiral-arc fins 122 are mounted on the pivot of the spiral-shaped spiral fins 122 in the two directions of the spiral shaft, and are supported by the bucket: Provided to the kneading portion 2. The raw material supplied from the / ° σ 5 ? 4 is supplied with the raw material of the metering feeder portion 4 (in the present invention, 嫱e is contained, P is continuously kneaded to process the soluble organic liquid and the resin or organic Material 1, water-soluble inorganic salt, water well derived The sol or gel present compound 4), which is supplied to the feed portion, is sometimes referred to as "kneading". The metering feeder portion 4 includes the 312XP/invention specification (supplement) /9M)8/95114255 200706604 == bucket 41, the screw feeder 42 from the bottom of the raw material funnel 41, and the connecting cylinder 43 from the outlet end of the outer casing η. 疋加科益42 44A/ The TV2 is moved such that its spiral fin is concentric with the intermediate cylinder opening and the bottom end of the upper inch 41 of the connecting cylinder 43 (the right side of FIG. 1): the value of the screw: the loader 42 is " Connected to the drive shaft of the feed motor shown in Figure 1. Therefore, by means of the pivoting of the screw feeder 42 due to the power feeding, the material in the bucket 41 is caused to pass through the intermediate circle with a predetermined amount of conveyance by the movement of the screw: the body η: the cylinder 43 is conveyed to the outer casing η. The W cylinder 44 and the connection kneading portion 2 include a plurality of fixed discs 21, a ring-shaped kneading cylinder 22, and a rotating disc 23, and the cylinders 22 are alternately disposed between the cylinders 22, the rotating discs 21 and the badly kneaded ancient hw, Then the surface and the back surface (in Fig. 1 = surface and left surface) are in a circular direction with the fixed disk 21? . Figure! The rod that is omitted in the middle is inserted through the above; two 21 and the kneading cylinder 22. The solid rod of the tie rod is mounted on the casing 11. Thus, the outer joint of the feeding portion 1 is fixed. The fixing disk 21 and the kneading cylinder 22 and the feeding portion i are respectively mounted on the swash plate shaft (the front end surface of the rotating rod 12 同 is concentrically extended), and the snail is screwed on every two adjacent rotating disks. Between 23 . ^ ^螺# 24 Ampoules 24 staggered mounted on the pinch shaft. The outer diameter of the outer turn = turntable 23 and the screw 疋褥 4 23 is slightly smaller than the kneading circle 312^mmmmm/95^08/95114255 12 200706604 The inner diameter of the cylinder 22 The outer diameter of the intermediate screw 24 is slightly smaller than the inner diameter of the fixed disk 21. For this reason, in the case where the rotary disk 23 and the intermediate screw 24 are alternately mounted on the pin groove shaft, the outer circumferential surfaces of the respective rotary disks 23 and the respective inter-spindle screws "24" respectively pass through the gap through which the raw material can pass and the kneading cylinder 22 is opposed to the inner circumferential surface of the fixed disk 21. Due to the above configuration of the kneading machine ίο, the raw material of the raw material funnel 41A is taken out from the bottom of the raw material funnel 41 by the driving of the screw feeder 42, and then introduced into the feeding portion through the intermediate cylinder 44 and the connecting cylinder 43. 1 in the outer casing n. The raw material introduced into the outer casing u is continuously conveyed to the kneading portion 2 on the downstream side by the rotation of the spiral fin 122 due to the driving rotation of the auger 12. Then, the raw material conveyed to the kneading portion 2 is first passed through the outer circumferential surface of the intermediate screw 24 which is rotated about the right side in the most upstream side (10) 1 and the gap between the outer circumferential surface of the upstream disk and the fixed disk 21_circumferential surface ! The left side surface of the fixed disk 21 on the most upstream side is the gap between the right side surfaces of the rotary disk 23 which is rotated about the axis on the most upstream side. When the original passes through these gaps, the material is kneaded. According to the number of solid two rounds = 2, the rotating disk 23 and the intermediate screw 24 are installed in the above-mentioned operation of the raw material. For this reason, organic pigments, water-soluble inorganic salts, and water-soluble organic substances in various inventions of raw materials are obtained by kneading the adjacent eight-dimensional kneading process. From the gap, that is, the outer circumferential surface and the inner circumferential surface 312XP of the kneading cylinder 22 on the downstream side of the rotary disk 23 on the most downstream side, between the invention specification (supplement)/95_〇8/95114255 13 200706604. Fig. 2 shows a front view (viewed from the right side of Fig. 1) or a rear view (viewed from the left side of the figure) of the fixed disk and the rotary table for the continuous kneading of the specific example shown in Fig. 2. In Fig. 2, (a) is a cavity sector-shaped fixed disk 21a, (b) is a cavity sector-shaped rotating disk 23b, (c) is a cavity rose-shaped fixed disk 2ic, (d) a cavity-shaped rose-shaped rotating disk 23d (e) is a cavity-shaped fixed disk 21 e, and (f) is a cavity-shaped rotating disk 23f. As shown in Fig. 2, each of the fixed disks 21 has a movable fitting hole 211 concentric with the intermediate screw 24, in which the intermediate screw 24 is to be loosely fitted. In the radial direction of the / tongue t-aligning hole 211, a plurality of recesses (cavities (shrinking spaces) 212) are formed in a hollow shape on the front and rear surfaces (front side and rear side) of each of the fixed disks 21, These notches are provided at regular intervals in the circumferential direction. On the other hand, each of the rotary disks 23 has a fitting hole 231 concentric with the bolt groove shaft, in which the bolt groove shaft omitted in Fig. 1 is assembled in a chopped contact manner. A cavity (shredding space) 232 corresponding to the cavity 212 of the fixed disk 21 is formed hollow on the front and rear surfaces of the respective rotary disks 23. The edges of the respective cavities 2 3 2 of the rotary disk 23 are open. Due to the driving of the auger 12, the material introduced into the gap between the fixed disk 21 and the rotary disk 23 is continuously advanced into the respective cavities 212 and 232. In this state, at the interface of the cavities 212 and 232, the pivoting turntable 23 produces shearing forces on the raw materials in the cavities 212 and 232. That is to say, 'the ridge portion of the cavities 212 and 232 partially cuts the cavity 212 of the fixed disk 21 opposed to each other and the material 2' in the cavity 2 3 of the rotating disk 2 3 to thereby generate shear force and replace the material on the raw material. Thus, the kneading and 312XP/invention specification (supplement)/95-〇g/95114255 14 200706604 disperse the raw material. During the above replacement process, the sheared material exits the cavities 212 and 232 and the new material enters the same cavity 212 and 232. Depending on the shape of the cavities 212 and 232, the fixed disk 21 and the rotary disk 23 are divided into a plurality of different kinds of fixed disks and rotating disks. That is, they respectively enter the cavity sector-shaped fixed disk 21a and the cavity sector-shaped rotating disk 23b shown in (a) and (b) of Fig. 2, and the cavities shown in (b) and (c) of Fig. 2, respectively. a rose-shaped fixed disk 21c and a cavity rose-shaped rotating disk 23d, and in FIG. 2 (the phantom and the cavity-shaped fixed disk 21 e and the cavity-shaped rotating disk 23f. These different kinds of fixed disks And the rotating disk is used to increase the shearing force acting on the raw material according to the kneading and dispersion treatment = progress. That is, from the highest to the lowest, the void ratio of the cavity 212 or 232 is sequentially ordered (the cavity 212 of the fixed disk 21 or the rotation) The area of the cavity 232 of the disk 23 is based on the percentage (%) of the surface area of the fixed disk 21 or the rotary disk 23) is a sector-shaped cavity 212 or 232, a rose-shaped cavity 212 or 232, and a dome-shaped cavity 212 and 232. The shearing force of the raw material increases as the void ratio decreases. - In this specific example, the fixed disk 21 having the sector-shaped cavity 212 and the rotating disk 23 having the sector-shaped cavity 232 are sequentially disposed from the upstream side to the downstream side and have a fixed disk 21 of the rose-shaped cavity 212 and having a rose-shaped void 2 2 = rotating disk 23; The fixed disk of the shaped cavity 212 and the rotating disk 23 having the dome-shaped cavity 232 increase the progress of the shearing force acting on the raw material to knead and disperse the raw material. Thus, the large t shear force is not suddenly applied. In the raw material, but with the progress of the kneading and dispersion treatment, the shearing action on the raw material is continuously increased 312XP / invention specification (supplement) / 95-08/95114255 Η 200706604 force. Therefore, without any additional strain In this case, the kneading and dispersion treatment are smoothly applied to the raw material. Thus, the organic pigment, the water-soluble inorganic salt, the water-soluble organic liquid and the resin or the organic dye derivative, the enema derivative or the three which are all raw material components can be obtained. The derivative is successfully kneaded and dispersed with each other. According to the continuous kneader 1 having such a structure, when the organic pigment as a raw material component is composed of coarse particles, by introducing the organic pigment to the fixed disk 21 and the rotary disk 23 The gap between the gaps (especially, the cavities 212 and 232) is applied to the coarse particles by the rotation of the rotary disk 23, and the coarse particles of the organic pigment can be pulverized into fine particles. On the other hand, when the organic pigment is composed of aggregates of fine particles, by introducing these aggregates into the gap between the fixed disk 21 and the rotary disk 23 (particularly, the cavities 212 and 232) and rotating the rotary disk 23 It is possible to stably crack and homogenize these aggregates. The pigment kneaded and dispersed by the above-described continuous kneader will be described in detail below by kneading an organic pigment, a water-soluble inorganic salt, a water-soluble organic liquid, and the like by a continuous kneader 10 A mixture of resins for obtaining the pigment composition of the present invention i, the continuous kneading machine 10 comprising a drive shaft 121, an annular fixed disk 21, a rotary disk 23 concentric with the fixed disk 21 and rotating around the axis of the drive shaft 121, and a fixed disk The pulverizing space formed in the gap between 21 and the rotary disk 23. The organic pigment used in the present invention refers to an organic pigment which is selected to have appropriate reaction conditions during synthesis to make the particle size fine and uniform, such as an azo pigment; in the post-treatment, the synthesis of agglomerated extremely fine particles After ^ 312 χ ρ / invention manual (supplement) / 95-08/95114255 16 200706604 organic pigments that make the particle size uniform, such as multi-colored phlegm pigment; and in the post-treatment, through the fine particles can make it in it An organic pigment having a uniform size of coarse particles and uneven particles produced in the synthesis, such as a copper-brown cyanine pigment. In addition, the organic pigment of 5H is not particularly limited in structure, as long as it is a pigment which requires finely divided and uniform in size. Just fine. The organic pigment can be selected from conventional organic pigments. Examples of the organic pigment include an azo pigment, an indigo pigment, and a quinone pigment, and also include an iso, porphyrin, iso-t-porphyrin, perylene, anthrone, diketopyrrolopyrrole, thioindigo, Two tillage, quinolone, anthraquinone and brewing.

Methyl Ether, Diethylene Glycol Monoethyl Ether The water-soluble organic liquid used in the present invention is added so that the organic pigment and the water-soluble inorganic salt form a uniform slurry. The water-soluble organic liquid is not particularly limited as long as it can be freely mixed with water, or even if it cannot be freed with water: δ kernel /, the solubility which is removed by the I industry water washing, and allows the growth of the pigment particles, that is, can. The liquid tends to evaporate easily due to an increase in temperature during kneading. For this reason, it is preferable to use a high boiling point agent in consideration of safety. For example, 2-(methoxy)ethanol, 2-butoxyethanol, 2-(oxy)ethanol, 2-(hexyloxy)ethanol, diethylene glycol, diethylene glycol, ethylene glycol monobutyl _, triethylene glycol, triethylene glycol monomethyl ether, liquid polyethylene glycol, methoxy-2-propanol, ethoxylated 2-propanol, dipropylene glycol, dipropylene glycol 312XP /Invention Manual (Supplement)/95-08/95114255 17 200706604 Mercaptoether, monopropylene glycol monoethyl ether, low molecular weight polypropylamine, bite, tetrahydrofuran, dioxane, methanol, ethanol, iso Propyl alcohol, n-propanol, isobutanol, n-butanol, ethylene glycol, propylene glycol, propylene glycol monomethyl ether acetate vinegar, acetic acid, isopropyl acetate, acetone, methyl ethyl ketone, dimercapto S & amine, Diterpenoids and N-methylpyrrolidone. A mixture of at least two organic liquids can be used as needed. The resin used in the present description is preferably a tree which is hardly soluble in water, is a liquid at room temperature, and is partially soluble in the water-soluble organic liquid used in the present invention.

In particular, rosin resins are preferred in view of the added effect and price. The amount of the water-soluble inorganic salt in the kneaded composition of the present invention is not particularly limited to #曰1. The amount of the water-soluble inorganic (tetra) is preferably from 〇 5 to an additional amount of the organic pigment. When it is less than 0.5 weight times, fine crushing is difficult. When 1 is more than ^ times the weight, it is possible to obtain a finely divided pigment, but the amount of the pigment to be treated becomes less so that the productivity is disadvantageously lowered industrially. 312XP/Invention Manual (Supplement), 95·〇8/95114255 The kneaded composition of the present invention (IV) The amount of the water-soluble organic liquid is not limited.

When the weight is greater than 1 · 0 L, the day's do not achieve the effect corresponding to the amount of resin added. Further, it is preferable to control the amount of the resin depending on the properties of the resin used in the obtained pigment composition and the vehicle resin. That is, when the difference is large, the resin is used in a minimum amount to reduce the influence on the physical properties of the vehicle resin. On the other hand, when the difference is small, the amount of the resin is preferably increased to sufficiently exhibit the effects of the present invention. 1 as an ingredient of the kneading composition of the present invention, an organic pigment, a water-soluble benefit, a salt, a water-soluble organic liquid and a resin may be simultaneously added to a continuous kneader separately.

The kneading composition of the spindle rotation number at 5 rpm and the kneading temperature of 9 (TC kneading temperature, 21 kg / 扦) is operated by the continuous kneading machine 1 〇 The electric power consumption for kneading is 8ω per lkg of pigment 。. The kneaded composition obtained by this 312XP/invention specification (supplement)/95_〇8/951 ία% 57 200706604 is taken out and poured into 70°. 5,000 parts of water in C. The mixture was stirred for 1 hour while maintaining the temperature, followed by filtration, washing with water and drying. 10 parts of the above pigment composition and 90 parts of varnish for gravure ink (nitrocellulose resin 12%, ethyl acetate 33%, toluene 30%, isopropanol 15% and methanol 1%) Mix with 1 part of 3-mm glass beads. Disperse with a paint adjuster for 60 minutes to prepare a gravure ink. Apply a gravure ink to the transparent film with a bar coater #4. Place the white and black paper. On the back side of the thus obtained coated article, the colorimetric was separately performed with a colorimeter. The difference in luminance L* (^L*) was 5.2. Δί* is generally used as a standard for transparency. When ΔL* is large The transparency was better. The following Comparative Examples 1 and 2 were carried out in which a kneading was carried out using a conventional two-arm kneader having a capacity of i〇〇〇. The comparative example contained no resin as a component of a conventional kneading material. The consumption of the medium electric power is less than the consumption of the electric power in the first example, but the gravure ink coating of the embodiment i is superior in transparency to the gravure ink coating of the comparative example. Comparative Example 2 and The composition used in Example 1 was the same, and also included the resin. The gravure ink of Comparative Example 2 was coated with π. π is superior in transparency to the gravure ink coating of Comparative Example 1. Thus, the effect of adding a resin was found. However, the transparency in the Example 要 was superior to that of Comparative Example 2. As a kneading device, the continuous kneading machine was excellent. The two-arm kneader is described below. Comparative Examples 3 and 4 are described below, in which the kneaded material contains no resin and the continuous kneader used in Example 1 is used.

Therefore, it can be appreciated that the resin is added to the examples. Comparative Example 4 reduced the amount of the water-soluble organic liquid used in Comparative Example 3 and increased the kneading energy by doubling the electric power consumption. The transparency of the gravure ink-coated article in Comparative Example 4 was substantially the same as that of Comparative Example 3. When the kneaded material contains no resin, it is limited in improving the transparency of the gravure ink coated article. Based on the above results, since a continuous kneader is used and a resin is mixed in the kneaded material, a pigment composition having a good actual quality represented by transparency can be obtained with a small amount of energy.

A method of measuring the contrast of the etchant-coated film, and a preparation example of the acrylic resin solution used in the examples. The original particle diameter of the pigment was measured by an ordinary method in which the size of the original particles was directly measured by an electron microscope. Specifically, the major axis diameter and the minor axis diameter of the pigment primary particles were measured, and the average values of the major axis diameter and the minor axis diameter were used as the particle diameter of the above pigment particles. For ruthenium or a plurality of pigment particles, the volume (weight) of each particle is individually obtained by taking an approximation of the hexahedron of the particle diameter obtained as above. The volume average particle diameter is taken as the average primary particle diameter. In the measurement by transmission electron microscopy (TEM) and scanning electron microscope (sem), almost the same results were obtained. The width ratio of the pigment was obtained by separately measuring the major axis diameter and the minor axis diameter of the pigment primary particles with an electron microscope and calculating according to the following equation. The aspect ratio, the aspect ratio of the approximate square crystal form of the preferred particles is approximately (length ratio) = (long axis diameter) / (short axis diameter) The specific surface area of the pigment particles is obtained by the BET method based on nitrogen adsorption. The measurement was carried out using an automatic vapor adsorption amount measuring instrument ("BELS0RP丨8", supplied by BEL Japan Inc.). Next, a method of measuring the contrast of a coating film prepared using a resist will be described with reference to FIG. Light emitted from the backlight element (7) for the liquid crystal display passes through the polarized polarizing plate (6), and the polarized light passes through the dried coating film (4) of the colored composition coated on the glass substrate (5) and reaches Polarizer (3). When the plane of polarization of the polarizing plate (6) is parallel to the plane of polarization of the polarizing plate (3), the polarizing plate (3) 312XP/invention specification (supplement)/95-08/95114255 69 200706604 transmits light. When the plane of polarization is vertical, the polarizing plate blocks light. However, when the light polarized by the polarizing plate (6) passes through the dried coating film (4) of the coloring composition, scattering occurs due to the pigment particles and an offset occurs on the partially polarized surface. In this case, when the polarizing plates are parallel, the amount of light transmitted through the polarizing plate (3) is lowered. When the polarizing plate is vertical, the polarizing plate (3) transmits a part of the light. The transmitted light is measured as the brightness on the polarizing plate. The ratio (contrast) of the brightness when the polarizing plates are parallel and the brightness when the polarizing plates are vertical is calculated. (Contrast) = (parallel brightness) / (vertical brightness) Therefore, when scattering occurs due to the coloring composition drying the pigment in the coating film (4), the parallel brightness is lowered and the vertical brightness is increased. Therefore, the contrast is reduced. Shaped 7C meter ("BM-5A", supplied by Topcon) used as luminance meter (1), polarizer ("NPF-G1220DUN", by Niu〇 Denk〇

Provided by Corporation) as a polarizing plate. In the measurement, a black mask (2) having i><icm square holes was placed on the measuring portion to block unnecessary light.

The hydrazine acrylic resin solution was cooled to room temperature, and then a part of the resin solution was sampled. The sample resin solution was dried at 180 ° C for 2 minutes and the content of nonvolatiles was measured. The cyclohexanone was added to the resin solution to change the content of the nonvolatile matter to 20%, thereby preparing an acrylic resin solution.

The mixture was kneaded at 100 ° C for 5 hours while the mixture was maintained in a dense slurry state. After the milling, the resulting mixture was taken out and poured into a 70 ° solution of 1,300 parts of 1% sulfuric acid. The mixture was allowed to wrestle for 1 hour, then filtered, washed with water, dried and pulverized, thereby obtaining a fine crude copper indigo pigment from 312XP/Invention Manual (Supplement)/95-08/95114255 80 200706604. The fine crude copper indigo pigment has a specific surface area of 99 m 2 /g. When observed by TEM (electron microscopy), all the pigment particles were finely pulverized and no coarse particles were found. However, the average primary particle diameter is -66·3 nm, and the aspect ratio is 丨·69. An alkali-developing blue resist was prepared in the same manner as in Example 15 using the fine crude copper ugly pigment obtained above. Table 3 shows the measurement results of the specific surface area, the average primary particle diameter, and the aspect ratio of the fine pigments obtained in Examples 15 to 20 and Comparative Examples 15 to 20. Three coated substrates having different film thicknesses were prepared for each of the antifungal agents obtained in Examples 15 to 20 and Comparative Examples 15 to 20. Each film thickness and each contrast was measured. The contrast at a film thickness of 2//m was obtained from the data of the above three coated substrates by the original correlation method. The anti-surname agent is applied to the substrate by changing the number of revolutions of the spin coater used so that each of the prepared coated substrates has a dry film thickness of about 1//m, and then 8 在 in a hot air tank. Dry it at °C for 30 minutes. The contrast ratio of the coating substrate prepared by using the resists obtained in Examples 15 to 20 was higher than that of the coating substrates prepared using the resists obtained in Comparative Examples 15 to 20. table 3
