Description

1354813. The method of making a light film and a light-sensitive film is a method in which a pigment which is excellent in light properties and heat is used as a so-called "pigment dispersion method" for a colorant. However, the color filter in which the pigment is generally dispersed has a problem of "disturbing the degree of polarization controlled by the liquid crystal" due to light scattering by the pigment. That is, when light must be blocked (〇 FF state), light leakage occurs, and when it is necessary to transmit light (0N state), light transmission attenuation occurs, and there is a brightness ratio of the display device in the "ON state and the 0FF state". (Bright contrast) is a low problem. In order to achieve high contrast of the color liquid crystal display device, that is, a color filter containing high contrast in suppressing light scattering or the like is obtained, and the pigment contained in the filter segment is subjected to miniaturization. Among the methods for refining the pigment, the method widely used today is the solvent salt milling method (10). The solvent salt milling method is to knead the coarse pigment particles by using an inorganic salt such as a gasification sodium or sodium sulfate as a grinding aid, and an ethylene glycol or a dibasic compound: a soluble organic solvent. The machine is: the method of micro-", 敕: micro-refinement. Although the solvent-salting method is an effective method for smashing the pigment granules, in the color filter, :/ is more contrasting' must be used. A finer and finer pigment than the pigment obtained by the previous solvent salt milling method. >'; and 'the amount and size of the abrasive auxiliaries are known for the pigments produced by the solvent salt milling method.

The salt used in the invention is based on the volume of the median diameter = 50) 1 to 50 " m, 95% particle size (〇95 Is a salt of 0.002 to 0.08 wt%, which is a function of a grinding aid when the organic pigment is refined. The volume-based median diameter (D50) of the salt is It is preferable to use 1 to 2 〇 #m, and 95% of the particle size (D95) is in the case of % of the claws. Further, especially in the case of seeking a high-contrast filter, it is preferable that the salt used in the miniaturization treatment of the organic pigment is fine, and it is possible to appropriately use the volume-based median diameter (D5). 〇) 1 to 1 〇 with claws, 95% particle size (D95) is 20/zm or less of salt. The salt having a median diameter (D50) of 1 to 50/m and a 95% particle diameter (D95) of 80 or less may be prepared by pulverizing raw salt such as commercially available salt. If the salt median diameter (D50) is more than 50 #m, it is impossible to obtain a fine organic pigment which is desired to be finely and uniformly sized. On the other hand, if the median particle size of the salt is less than 1 // m ', it is necessary to use a special pulverizer and consume a large amount of energy, and it is difficult to obtain such a salt itself. Further, if the food has a 95% particle diameter (D95) of more than 80 // m, the coarse salt particles increase, which is a main cause of a decrease in the pulverization efficiency, and it is difficult to obtain a desired fine pigment. % • Further, the lower limit of the 95% particle size (D95) of the salt is the median diameter (D50). • The volume-based median diameter (D50) and 95% particle size of the salt are calculated using the laser-refractive Microtrac particle size analyzer from the measured particle size distribution. The D50 and D95 particle sizes mean the following Particles of particle size: based on volume, accounting for 50% and 95% of the total particles. The factor affecting the refinement of the organic pigment, in addition to the particle size of the salt, is the shape of the salt. From the viewpoint of producing fine organic pigments which are finely divided into uniform particle diameters, the salt having an angular shape is better than the round salt. The volume-based median diameter (D50) is 1 to 50 # m, and the 95% particle diameter (D95) is 80; the salt below zm can be obtained by pulverizing the raw material salt having a large particle size, but pulverizing The shape of the salt varies depending on the amount of Mg in the raw salt. When the content of Mg in the raw salt is more than 0.08% by weight, the shape is rounded and the shape is rounded to form a salt particle having a smooth surface. On the other hand, when the raw material salt having a Mg content of 0.08% by weight or less is pulverized, the salt particles having a sharp horn and a rough surface are obtained. Further, the salt having a Mg content of less than 0.002% by weight is a salt of a sample grade, and the cost becomes high, which is industrially difficult to use. Therefore, the salt used in the present invention has a Mg content of 0.002 to 0.08 by weight. /. Among them, a salt having a Mg content in the range of 0.005 to 0.05% by weight is preferred. Further, as for the quality of the salt, it is preferred that the water content is low. Industry 13 318785 丄354813 曰C 'Lian (containing more than 9 5 gasification) usually contains 1% by weight. The water on the sputum 'If the moisture content is 1.0% or more, the salt is dried. It is pulverized as it is, and the smashed salt has strong adhesion. If it is placed, it will cure quickly. The solidified salt will cause the efficiency of the micronization to be reduced. The micro-grinding becomes meaningless. In order to maintain the granules during pulverization, the pulverized salt is preferably dried to a moisture content of 5% by weight or less, and more preferably dried to a moisture content of 3% by weight or less. Among them, it is particularly preferable to sinter the food at a high temperature to a moisture content of 〇 2% by weight or less. The lower limit of the moisture content is not particularly limited, and is preferably 〇% by weight. In the present invention t, it is preferred to dry the salt before the pulverization, and the salt may be dried after the pulverization. The temperature at the time of drying is preferably from 1 Torr to 4 Torr, and the drying time can be appropriately set depending on the type of pulverizer used in the pulverization. In the pulverizer for crushing salt, a high-speed rotary grinder such as a honing machine (hmmermiH) or a pin mill is generally used. However, the type of the masher is not limited. The slewing speed, time, and the like at the time of pulverization can be appropriately set depending on the desired salt. Although the amount of salt used varies depending on the type of organic pigment, it is based on 1 part by weight of the organic pigment. It is preferably from 3 parts by weight, more preferably from 5 to 15 parts by weight. The ratio of salt to organic pigment is larger, and the effect of trial refinement is larger. However, the amount of primary treatment is less, which is the main reason for the ancient product. In the present invention, the use amount of the salt is not increased by using a specific particle size and a salt content, but the high-quality fine organic pigment is efficiently produced. The water-soluble organic solvent used in the present invention is dissolved! It is preferred to use a mixture of the organic material 318785 14 1354813 and the salt as a dough of appropriate hardness to use a solvent which is soluble in water and does not substantially dissolve the salt. The water-soluble % organic solvent is preferably a water-soluble organic solvent having high viscosity such as ethylene glycol, diethylene glycol or polyethylene glycol. The amount of the water-soluble organic solvent to be used varies depending on the kind of the organic pigment and the amount of the salt, but is usually 0.1 to 5 parts by weight, and preferably 1 to 2 parts by weight, based on 1 part by weight of the organic pigment. . The temperature at which the organic pigment is refined is preferably 120 ° C or less, and particularly preferably 20 to 701 : from the viewpoint of finely impregnating the organic pigment. Further, the treatment time varies depending on the type of the organic pigment and the particle size of the salt, and is usually about 2 to 20 hours. A device which kneads a mixture containing an organic pigment, a salt, and a water-soluble organic solvent may be used as long as it can mechanically grind the organic pigment. A typical apparatus may be a kneader. In addition, a batch type mixer such as a super mixer (manufactured by Kawata Co., Ltd.), a three-armed planetary mixer (Tri-mix) (manufactured by Inoue Seisakusho Co., Ltd.), or a KCK grinding machine can be used. Continuous kneading machine such as machine (made by Asada Iron Works Co., Ltd.). Also, devices other than these can be used. Before kneading or kneading a mixture containing an organic pigment, a salt, and a water-soluble organic solvent, a resin, a surfactant, or the like may be added as needed.

The resin may be used singly or in combination of two or more. For the agglomerate obtained by the completion of the mixture of the organic pigment, the salt and the water-soluble organic solvent, it is preferred to take out the finely divided organic pigment particles (having an average particle diameter of from about 1 to about 5 (four)). ) and remove salt and water-soluble organic solvent, generally by filtration, washing with water, and the like. First, put the ghosts into the water and heat until the salt is completely dissolved. The heating temperature and the amount of warm water, ^ can completely dissolve the salt, there is no limit. At this time, the high-speed temples are used, and the agglomerates in the water are added to form a liquid. Next, the mash is washed, washed with water, a salt and a water-soluble organic solvent by a filter such as a filter press. When washing, the degree of washing can be adjusted according to the sputum. By washing with water, you can get a press cake. The pressed cake which is taken out by the machine is smashed with a box dryer or with a fine organic pigment and can be formed into a powder micro-dryer. @t, the degree of water is added to the water, and the spray can also be formed by spraying A fine organic pigment in powder form.

Table 1 shows the results of measurement of the specific surface area and particle size of the aphid 4 children and the micronized pigments obtained in the respective examples and comparative examples. Further, using the resists obtained in the examples and the comparative examples, three kinds of coated substrates having different film thicknesses were produced, and the respective film thicknesses and contrasts were measured. A comparison method was used to obtain a comparison of 2//m from the 3 _ point data. The results are shown in Table 2. Further, the coated substrate was produced by applying a resist to the substrate at a number of revolutions, changing the thickness of the dried film to about ^, and drying it in an 80 C hot air oven for 3 minutes. 318785 51 1354813 The coated substrates produced by using the resists obtained in Examples 1 to 4, γ were compared with the coated substrates prepared by the resists obtained in Comparative Examples 1 to 4, and the enthalpy ratio was increased. • 乂 '封 [Table 1] Example I Example 2 Example 3 - Example 4 Comparative Example 1 Comparative Example 2 Comparison ~ Example 3 Pigment Yellow Pigment I - Blue Pigment 1 - ...
