Description

200949311 VI. Description of the Invention: [Technical Field] The present invention relates to a method of producing a color filter and an ink for color filter used therein. [Prior Art] The color filter used in the liquid crystal display has a transparent substrate and three colors of red, green, and blue formed on the surface thereof, or, for example, four colors in which yellow is added or five colors in which cyan is further added. Colored layer. From the viewpoint of the image quality of the liquid crystal display, it is desirable that the surface of the colored layer is flat (the difference in film thickness between the outer edge portion and the central portion of the colored layer is small), and the thickness between the color layers is uneven (colored layer). The height difference of the surface is small. Further, in recent years, as a method of producing a color filter, a method of printing an ink pattern formed of a colored ink on a transparent substrate and then curing the ink pattern to form a colored layer has been proposed. (4) In order to flatten the surface of the colored layer, it is proposed to pressurize the ink pattern on the transparent substrate with a roller (Patent Document 1). However, the viscosity of the colored layer forming ink differs depending on the coloring agent to be blended, and the thixotropy is different, which causes a difference in printing characteristics. Therefore, there is a possibility that the line width unevenness of the ink pattern occurs due to the difference in the ink for forming the colored layer. In addition, the unevenness of the line width of the ink pattern causes unevenness in the gap with the adjacent ink pattern, and further, the abutment portion of the ink pattern ^200949311 and the adjacent ink pattern is disordered, 2 _ mouth portion In the case of the problem of the inconsistency of the ink color mixing, the bonding method contained in the different inks of the ink for forming the color layer of the ink pattern can be set, for example, by adjusting the oil method. However, in the method of the partial reduction of the tenth "tree θ" and the dilution degree of the ink, the ink pattern accompanying the solidification is remarkably collected, and the thickness between the colored layers is too much to be inferior to the flatness of the i color layer. Bad conditions such as damage. The lines between the layers provide the color that can suppress the color from each other. (4): and the appropriate::====Transparent: Substrate increase each of the above-mentioned Baogu system Further, the ink pattern is cured to form a coloring layer, and the tri-upper ink contains a weight average molecular weight, a binder of ～3〇_, a coloring agent, a property-imparting agent, and a handle' and a shearing speed The viscosity at Is-1 is 1〇~2〇Pa s, the viscosity η12 (Pa.s) when the shear rate is Is-1, and the viscosity η12 (Pa.s) when the shear rate is 12 wide. The ratio of thixotropy index τ 1.1-1.7 represented by ηι/ηΐ2 〇 According to the manufacturing method, it is possible to obtain a balance of printing characteristics or curing characteristics between inks having mutually different colors, and to form a line width or thickness of the pattern 200949311 A color-developing layer having a flat surface which is unevenly suppressed. In the above invention, an offset is preferably used. The ink is printed by a brushing method or a reverse printing method. By printing by an offset printing method or a reverse printing method, the printing accuracy of the ink pattern is improved, and a coloring layer having a very small line width can be formed with high precision, so that an image can be produced. In the above invention, it is preferable that the difference in weight average molecular weight of the binder resin between each of the inks is 17500 or less. The difference in weight average molecular weight of the kneading_lipid is set. In the upper circumference 1 to adjust the balance of the curing characteristics between the inks having different colors from each other', it is possible to suppress the unevenness of the line width or the thickness of the colored layer. In the above invention, 'the above between the respective inks is preferable. The difference in thixotropy index TI is below 〇·4〇. By setting the thixotropy index TI to the above range, you can

Si:; A balance of printing characteristics is obtained between the inks, whereby unevenness in line width or thickness of the color layer can be suppressed. Further, the ink for color filter of the present invention is characterized in that the binder ==== 7-side adhesive _, colorant, = degree is 1 s-1, _degree ^= and shear i = = (-pa. s) ratio is "~ indicates the above thixotropic change = in: the color of the lake color layer is different from each other on the three inks, by using the ink on the material view 4, can be different in the color 200949311 ink A balance between printing characteristics and curing characteristics is obtained. Further, it is possible to form a coloring layer having a flat surface, a line width, or a thickness unevenness. [Effect of the Invention] The color filter manufacturing method and filter according to the present invention In the ink for color chips, since the line width or thickness unevenness between the color layers different in color can be suppressed, a color filter having high image quality can be obtained. / The above and other objects of the present invention are made. The preferred embodiment is more clearly understood, and the preferred embodiments are described below in detail with reference to the accompanying drawings. [Embodiment] In the method for manufacturing a color filter of the present invention, first, the colors are different from each other. Three or more inks are sequentially printed on a transparent substrate, The ink contains a binder resin having a weight average molecular weight of 4 7 Å to fine enthalpy, a colorant, a thixotropic imparting agent, and a solvent. The weight average molecular weight of the binder resin contained in the ink is ❹7_~3_G. The average molecular weight of the towel is determined by the gel permeation chromatography (GPC) method and is obtained by standard polyethylene exchange (the lower molecular weight is 5 Π.), when the weight average molecular weight of the binder resin is within the above range, As described later, the progress of the printing characteristics or the curing characteristics of the inks of the respective colors can be obtained by reducing the viscosity of the inks of the respective colors to γ or by thixotropy. On the other hand, when the weight average molecular weight of the bonded petrolatum is outside the above range 200949311, it is difficult to set the viscosity or thixotropy of the ink within a predetermined range. Further, when the weight average molecular weight of the binder resin is outside the above range, for example, ' When the ink pattern is formed by the offset printing method, the transfer is not easily performed when the ink is transferred from the printing plate to the blanket, and the ink is transferred from the blanket to the transparent substrate. Further, when the ink pattern is formed by the reverse printing method, when the ink on the blanket is removed by the embossing plate, the removal failure is likely to occur or the transfer of the ink from the blanket to the transparent substrate is liable to cause transfer failure. The weight average molecular weight is in the above range, preferably 7000 to 23000, more preferably 75 Å to 2 Torr. Further, when the weight average molecular weight of the binder resin differs greatly between inks having different colors, the ink is different from the ink. The amount of reduction in the pattern volume accompanying the curing and the calcination is greatly different depending on the ink, and thus the unevenness of the line width or thickness of the colored layer may become remarkable. Therefore, in the method for producing the color filter described above The difference in weight average molecular weight of the binder resin between the inks having different colors is set as small as possible. Specifically, the difference in weight average molecular weight of the binder resin between inks having different colors is preferably 17500 or less, more preferably 15,000 or less, and particularly preferably 12500 or less.

As the coloring agent contained in the ink, various coloring agents made of the layer can be used, and the color can be selected according to the color required for the ink 200949311 (color tone of the colored layer) using red, blue, and green. In general, the coloring layer of the color filter is suitable for preparing red enamel = so-called fine three-views, so that it is appropriately selected, in addition to the red, blue, and white ink-based coloring agents.

The blending amount of the colorant is appropriately set in consideration of the color required for the ink, the light transmittance of the colored layer, the viscosity of the ink, or the thixotropy.

In addition, the thixotropy-imparting agent is appropriately selected depending on the composition of the ink to be shaken and steep, in particular, depending on the type of the resin or the pigment of the ink. Θ When a polyester-melamine resin or a polyester tree is used as the binder resin of the ink, it is not limited as a thixotropy-imparting agent, and can be listed as a product such as BYK_CHEMIE Co., Ltd. "BYK-R605", "BYK_R6〇6" of the same company; for example, the pyrolysis dioxide dream of Japan AEROSIL Co., Ltd., the trade name "AEROSIL (R) 200", the same company's "AER 〇 SIL (8) R2 〇 2,; for example; Rohm and Haas Company's trade name "1^_825", etc. The amount of the thixotropy-imparting agent is appropriately set in accordance with the printing characteristics of the ink, particularly the viscosity and thixotropy of the ink, and is appropriately set according to the blending amount of the pigment. The amount of the agent is preferably 5% by weight of the pigment, more preferably 0.2 to 4.0% by weight, particularly preferably 〇3 to 3.0% by weight.

These agents may be used singly or in combination of two or more. As a preferable example of the solvent, from the viewpoint of improving the drying property of the ink, the printing suitability = (▲ ink transfer property, etc.), and the balance of flatness, examples thereof include alcohol behenyl alcohol and pentadecyl alcohol. Higher alcohol. In addition, when using these south alcohols, in order to adjust the dryness and flow of the ink, it is also possible to use butyl carbitol, butyl cellosolve, ethyl carbitol, butyl cellosolve acetic acid which is faster than the higher alcohol. Ester, butyl carbitol acetate (BCA), terpineol, and the like. 13 200949311 , 夕 ' ' From the viewpoint of printing suitability of ink, etc., it is possible to use a solvent such as BCA, butyl carbitol, butyl cellosolve, ethyl carbitol, or ketone acetate vinegar. Or mixing them with each other so that the compounding amount of the agent is a knife considering the adhesion of the fat, the fresh colored component, the printing property of the ink (especially the viscosity and thixotropy of the ink), and the volatilization and weight loss between the inks. The balance is equal to the #定的. Therefore, it is not particularly limited, but is usually 15 to 35 parts by weight with respect to the weight of the adhesive i (10), and preferably 2 () to _ is particularly preferably 25 to 1 part by weight. The T is used as the binder resin, and the weight average molecular weight is set in the above-mentioned formula: the amount of the compound in the above-mentioned range is 1 (8) by weight of the adhesive surface. It is preferably 15 to 100 parts by weight, more preferably 20 to 50 parts by weight, particularly preferably 25 to 40 parts by weight. Further, the content ratio of the solvent is preferably from 1 to 45% by weight based on the total amount of the ink, and is from about 12 to 25% by weight in the amount of about -22% by weight. In addition, when the ratio of the solvent between the inks having different colors differs greatly, the amount of pattern volume reduction accompanying the curing and simmering of the ink greatly differs depending on the ink, and thus it is possible to cause coloration. The unevenness of the line width or thickness of the layer becomes remarkable. Therefore, in the method for producing a color filter, the content ratio of the solvent (the ratio of the solvent to the total amount of the ink in 200949311 (%)) between the inks having different colors is set to be as small as possible. Specifically, the difference in the content ratio of the solvent between the inks having different colors from each other is preferably 5% or less, more preferably 10% or less. Since the above inks obtain a balance of printing characteristics between inks having mutually different colors, the viscosity at a shear rate of ls-i is set to 10 to 20 Pa*s' and the shear rate is ls-i. Viscosity ηι (Pa.s) ❹ ❹ The ratio of the viscosity t|i2 (Pa.s) at a shear rate of 12 s, that is, the thixotropic index r expressed by rji/rjn is set to 1.1 to 1.7.

Among them, the viscosity claw (Pa.s) when the shear rate is Is-1 and the viscosity η12 (Pa.s) when the shear rate is 12s 1 are both cone plate type rotary viscometer (cone plate type, BR〇) Measured by 23 K: The measured value at 23t: (the same applies hereinafter). In addition, the thixotropy index 油墨 of the ink is = the ratio of the viscosity ηι (Pa.s) when the cutting speed is Is-1 to the shear rate of the shearing ratio, that is, 12 indicates (10), indicating that the shearing speed of the ink ink is γ. The viscosity of the time m or the balance of the above thixotropic property. In terms of the printing characteristics of the inks of different colors, or the other aspect, the shearing speed of the ink is ls~丨15 200949311. The viscosity at the time when the cutting speed is 1S-1 is "11" in the above range. For the viscosity point of the ink when the shear rate is 12 s-1, the viscosity point 2 2 is set from the contact index TI to a suitable range of ί" 20 to 300 Pa.s, further preferably 5. ~: the gradual change index of the observation When TI, j, and U, the ink flowability becomes too high during printing or ink printing, so the fine pattern = P: the accuracy is lowered. Conversely, when the thixotropy index TI is greater than L7, In the flattening treatment of the λ* pattern, the effect of planarization is lowered. The thixotropy index TI is preferably 1.2 to 1.6 in the above range. The viscosity of the stainless steel non-destructive ink is _, which can be used, for example, in the above-mentioned oil workers. The dispersant, the bulk f pigment, the antifoaming agent, and the thixotropy-imparting agent are specific components. As the dispersing agent, for example, it is mainly used to increase the age of the coloring agent in the ink. Specifically, as the lion dispersing agent , can be listed, for example, high by AJINOMOTO FINE-TEChn〇 Co., Ltd. Molecular pigment dispersant, trade name "AJISpER, series 彳 company's shop (4), trade name "pure P (four), (4) Dispersant made by the company, trade name "FL0WLEN, series, etc.". In the method for producing a color filter of the present invention, after three or more kinds of inks having different colors from each other are sequentially applied to a transparent substrate, the ink pattern formed on the surface of the transparent substrate is planarized and cured. Thus, a color filter having a transparent substrate and a colored layer formed on the surface thereof was produced. When the ink is printed on a transparent substrate, an offset printing method or a reverse printing method of 200949311 is used. Examples of the offset printing method include various prepress methods corresponding to printing plate counts, such as gravure offset printing and flat offset printing. This printing method of the printed lion is not particularly limited, but it is preferably a gravure pad from the viewpoint of forming a fine pattern of a color layer in the south accurately. A gravure, a blanket, an offset printing apparatus, or the like used for gravure offset printing can be suitably selected by using a method of manufacturing a method.

This is not limited. For example, as a blanket, from the viewpoint of forming an ink pattern corresponding to the finely colored layer with high printing accuracy, it is preferable to use a ketone blanket in which the ink carrying surface is formed of a rubber. In addition, examples of the substrate which supports the ink carrying surface include a film made of polyethylene terephthalate (PET). As the shape of the brewing material (4) _ _ lang, in addition, for example, 岐 can be set on the glass substrate, and the material of the metal film is formed on the surface of the concave portion by the electric g (so-called "electrical concave printing" When the gravure offset printing method is used, the surface of the ink substrate on the transparent substrate for flattening the ink pattern on the transparent substrate, and the member of the ink pattern == 17 200949311, for example, may be exemplified as light. Properties: flat: denier: for example, a sheet member formed by winding an oil such as a rubber sheet or the like on a mold material (for example, an axis of a bottomed cylindrical container: a material which is in the form of an upper roll; for example, a core liquid ketone rubber which extends along the bottom of the core material and which extends through the bottom portion of the core material, so as to release a two-soil release material (for example, a roll-shaped substance, etc.) The above-mentioned ink release material is made into a material with a small column of material = rubber, tension. Free Moon b (Critical Surface Case == Tan:: a pattern of scented ink, divided into 5 liters of oil /cm2' is further preferably 2 to) preferably 1 to 2, and the rotation speed is preferably 5 to 1 G. ()mm/min gCm, light ❹ on the ink pattern, such as brush (4) blanket 'gravure or letterpress (embossed version), ink film corresponding to the non-line portion in the reverse formed ink film = two leather cloth , = version, reverse printing device, etc. can be appropriately selected and used in the manufacturing method of the color filter caused by reverse printing. It should be said that the date is not limited as a rubber forest, for example, the rubber used in gravure offset printing. In addition, the material for forming the embossed plate is not particularly limited, and the rubber sheet is not particularly limited. For example, it is preferable that the rubber used in the f-type offset printing is the same stone. In the case of glass, metal, etc., it is exemplified that the substrate is provided on a substrate such as glass, and the material is formed on the surface of the concave portion and the convex portion by an electric clock method. In the reverse printing method, since the cross-sectional shape of the ink pattern on the transparent substrate is a rectangular shape, the flattening process of the ink pattern is not required. Printing on the surface of the transparent substrate, as needed The ruthenium ink pattern which has been subjected to the planarization treatment is further heated at 200 to 25 (TC, more preferably 220 to 240 C, and usually 1 Torr to 4 Torr, more preferably 2 Torr to 3 Torr, Thus, a color filter having a colored layer on the surface of the transparent substrate is obtained. The method for producing a color filter according to the present invention, for example, is formed to have a width of about 30 to 160 μm and a thickness of 1. 〇 before the curing treatment of the ink. In the case of a finely striped ink pattern of about 10 μm, the maximum value of the difference (unevenness) of the printing line width (before ink curing) in the same stripe pattern can be preferably set to 0.3 μm or less. In addition, in the method for producing a color filter according to the present invention, for example, after the curing treatment of the ink, three or more inks having different colors are formed to have a width of about 80 to 120 μm and a thickness. In the case of a finely striped ink pattern of about 1.9 to 2·2 μm, the difference between the printing line width (before the ink is cured) between the ink patterns having different colors can be obtained ( Average) the maximum value is preferably set Ο.ίμιη less, more preferably set 〇.〇5μιη less. Further, in this case, the maximum value of the difference (unevenness) between the pattern thicknesses between the ink patterns (before ink curing) in which the colors are different from each other is preferably 19 200949311 and is set to 0.15 or less.

The drying property of the ink, etc., starts from the ink which is not easy to dry, and when it is used as the colored layer, the ink pattern of the color is formed together with the above-mentioned three-color ink pattern. In the above printing step, a printing step of performing ink transfer from the ς color ink pattern (4) gravure to the (four) plate may be added.
