Description

1363930 IX. INSTRUCTIONS: » Technical Field of the Invention The present invention relates to a coloring composition for use in a color filter, and a color filter and a color filter using the coloring composition. In the method, the color filter is used in a color liquid crystal display device, a color camera element, or the like. [Prior Art] A color filter constituting a liquid crystal display device (LCD) or a color image pickup device (CCD) is formed by applying a coating liquid (a coloring composition for a color filter) to a transparent substrate and drying it. It is manufactured by a coating film having a thickness of about several micrometers. The coating method can suitably employ a spin coating method, a die coating method, or the like according to the characteristics thereof. * The spin coating method is widely used in a method of forming a film on a relatively small-sized substrate by rotating the transparent substrate at a constant number of rotations while dropping the coating liquid at the center of the transparent substrate. The coating liquid is thinly extended by centrifugal force, and a coating film _1 coating method requiring a film thickness is formed on the surface of the transparent substrate by controlling the number of rotations or the rotation time of the transparent substrate suitable for the coating liquid. However, the principle that the coating film is thinly extended by the centrifugal force of the rotation is disadvantageous in that the thickness of the coating film in the center portion and the peripheral portion of the transparent substrate is too thick when compared with the intermediate portion. Japanese Laid-Open Patent Publication No. Hei 6-3521 discloses a spin coating method. The composition used is a composition containing a solvent having a boiling point of 5% by weight or more or a vapor pressure within a specific range. Excellent surface smoothness. When the size of the substrate is large, the die coating method is employed because of the large load on the device due to the method of rotating the substrate by the spin coating method. 1363930

Various solutions are proposed in Japanese Laid-Open Patent Publication No. 2003-55566, JP-A-2004-346218, and JP-A No. 10-104825. Japanese Laid-Open Patent Publication No. 2003-55566 and JP-A No. 2004-346218 disclose a method of preventing a coating liquid from being exposed to external air by drying with a solvent having a high boiling point, and curing, so that aggregates are not generated. The method described in Japanese Laid-Open Patent Publication No. Hei 10-104825 is a method in which the evaporation rate of the solvent composition is within a specific range, and the invention is directed to an increase in adhesiveness due to a solvent having a high boiling point, even after a coating film drying process. The adhesion (adhesiveness) of the post-coating film cannot eliminate the disadvantages. [Explanation] [Problems to be Solved by the Invention] The following disadvantages can be observed due to the coating method of the spin coating method or the die coating method and the properties of the coating liquid to be used. Uneven film thickness means that the uniformity of the film thickness is insufficient, and can be classified into the following two categories, including "film thickness uniformity (end portion), that is, the film thickness uniformity of the end face is insufficient, and "the film thickness is uniform (except for the end), that is, the film thickness uniformity from the center of the substrate to the end of the substrate is not enough. 1363930 shape. Uneven stripes: can be classified into the following two categories, including "horizontal stripe unevenness", that is, coating on the die In the manner of the stripe unevenness caused by the direction perpendicular to the direction in which the slit is formed, and the "longitudinal stripe unevenness", that is, the slit coating direction is caused by the slit of the agglomerate of the slit opening portion. Stripe unevenness. It

Adhesive: It means that the adhesion of the film cannot be eliminated even after drying by natural drying, heat drying or drying under vacuum. The time-lapse of the coating liquid is unstable: the viscosity at the time changes with respect to the initial viscosity of the coating liquid, that is, the insufficient "time stability". It is a problem to reduce the above-mentioned disadvantages, and the method described in the above patent document which only has a high boiling point solvent and the method of evaporating the solvent composition within a specific range cannot sufficiently eliminate the above disadvantages. SUMMARY OF THE INVENTION An object of the present invention is to provide a coloring composition for a color filter which can reduce the amount of a coating material produced by a spin coating method or a die coating method.

A defect that can be observed on a coating film, and a color filter are provided, and a filter sheet formed of the coloring composition for the color filter is used. According to a first aspect of the present invention, a coloring composition for a color filter is characterized in that a transparent resin, a coloring material, and an organic solvent are contained, and the organic solvent contains a boiling point of 760 mm Hg. 16 (organic solvent A having a conductivity of less than 260 ° C and a conductivity of 0.001 nS/cm or more and less than 0.8 nS/cm at 25 ° C, and a boiling point of 760 mm Hg of 100 ° C or more and less than 160 ° C and An organic solvent having a conductivity of 0.8 nS/cm or more and less than 50 nS/cm at 25 ° C, based on the total amount of the organic solvent, containing 33.9 wt% or more and less than 60 wt%, having 1363930 machine solvent A, based on an organic solvent The total amount is 40% by weight or more and less than 95% by weight of the organic solvent B. Further, according to a second aspect of the present invention, there is provided a color filter comprising the color of the first aspect of the present invention. A filter segment formed by a coloring composition for a filter. According to a third aspect of the invention, there is provided a method for producing a color filter, which is characterized by a spin coating method or a die coating method on a substrate. Coating as in the present invention The color filter of the first aspect is a coloring composition to form a filter. [Effect of the Invention] The coloring composition of the present invention contains a boiling point and a specific conductivity within a specific range in a specific ratio. The organic solvent A and the organic solvent B are excellent in stability over time. Further, the coating film coated with the colored group can reduce the film thickness unevenness, uneven streaks, and adhesive residue, and the film thickness is uniform. Further, the color filter of the present invention has excellent quality because it has a ruthenium sheet formed of the φ coloring composition of the color filter described above. 1 Coloring of the color filter of the present invention When the composition is used to manufacture a color filter by a spin coating method or a die coating method, the formed filter sheet has a very good quality. [Embodiment] First, the color of the present invention will be more specifically described. The coloring composition for a color filter of the present invention contains a transparent resin, a coloring material, and an organic solvent. The organic solvent contains specific An organic solvent A having a boiling point and a specific conductivity of 1363930, and an organic solvent B having a specific boiling point and a specific electrical conductivity. Further, in the total organic solvent, the organic solvent a and the organic solvent B each occupy a specific ratio. The conductivity of the invention was measured using a conductivity meter Model 645 and 627 manufactured by SCIENTIFICA. <Organic solvent> The organic solvent used in the present invention, the organic solvent A and the organic solvent B constituting the organic solvent The respective boiling points, electrical conductivity, and the weight ratio of the two in the total organic solvent are each within a specific range" by combining organic solvents having such specific ranges of boiling points and electrical conductivity in a specific range ratio. The organic solvent A and the organic solvent B can constitute a coloring composition for a color filter which can reduce the disadvantages of the aforementioned coating material. The boiling point of the organic solvent is related to the drying property of the colored filter (hereinafter referred to as "coating liquid"), and when the low boiling point solvent is too much, it is in the slit of the die coater. In the opening portion, the coating liquid is easily dried, and a cured product is likely to be generated. On the other hand, when the solvent having a high boiling point is too large, the adhesion of the coating film (adhesiveness of the surface of the coating film) after the overcoat film drying process cannot be eliminated. As a result, in addition to the adhesion of the surface of the coating film, there is a case where the reticle is contaminated in the proximity exposure machine. Further, when a large amount of the organic solvent remains in the coating film, the coating film may be peeled off from the glass substrate, particularly the glass substrate having the SiO 2 film on the surface, during development. Further, the material constituting the coating liquid is related to the conductivity of the coating liquid in addition to the special case of adding a strong ionic material, for example, the conductivity of the solvent contained in the coating liquid. When the conductivity of the coating liquid is too high, the affinity with moisture in the external air increases, and the stability over time is 1363930 due to absorption of moisture, and conversely, when the conductivity in the coating liquid is too low, the liquid When the charging property is increased, the coating liquid is unstable from the slit discharge property, and coating unevenness (lateral stripe unevenness) is likely to occur. Further, since the coating liquid is charged, the liquid tends to concentrate on the outer peripheral portion of the coating film, and the outer peripheral portion of the coating film is raised. In order to optimize the above characteristics, the boiling point and electrical conductivity of the organic solvent A and the organic solvent B in the organic solvent used for the coloring composition for a color filter of the present invention and the ratio of the two in the total organic solvent are important. Namely, the organic solvent A is an organic solvent having a boiling point of 760 mmHg of 160 °C or more and less than 250 °C, and a conductivity of 251 of 0.001 nS/cm or more and less than 0.8 nS/cm. Further, the solubility parameter (SP) 値 (5 SA) of the organic solvent A is preferably 8.5 (cal/cm 3 ) 丨 / 2 or more and 13.5 (cal / cm 3 ) W 2 or less. Here, the SP値 of the organic solvent refers to the enthalpy obtained from the physical quantity (evaporation heat, surface tension, etc.) of the organic solvent, and is described in various documents. Further, the organic solvent A preferably has a high solubility in a transparent resin used for a coloring composition for a color filter. That is, the difference between the solubility I degree parameter of the transparent resin and the solubility parameter &lt;5 SA of the organic solvent A is preferably less than or equal to 0.25 (cal/cm3) 1/2. When the solubility parameter of the organic solvent is close to the solubility parameter of the transparent resin, the solubility of the resin increases, and the curing of the coating liquid can be prevented. On the contrary, there will be a tendency to lack stability over time. • However, by using an organic solvent A having a characteristic of low conductivity, it is possible to supplement the stability over time. Examples of such an organic solvent A include cyclohexanol acetate, diethylene glycol diethyl ether, ethyl 3-ethoxypropionate, propylene glycol diacetate, carbitol acetate, and butyl acetate. Carbitol ester and the like. Since the boiling point is not too high and the conductivity -10- 1363930 is low and the solubility parameter is appropriate, it is preferred to use cyclohexanol acetate. That is, in the present invention, the organic solvent A is composed of cyclohexanol acetate alone or by cyclohexanol acetate and another organic solvent A (other than cyclohexanol acetate). The organic solvent A is preferably referred to as a mixture of "organic solvent A' j ) '. When the organic solvent A is composed of a mixture of cyclohexanol acetate and an organic solvent A', cyclohexanol B in the mixture The ratio of the acid ester is preferably 1% by weight or more (less than 100%). Further, the solubility parameter of the mixture of the plurality of organic solvents is obtained by multiplying the solubility parameter of each organic solvent in the organic solvent. The total amount of each organic solvent is obtained by adding the weight fraction of each organic solvent (the ratio of the organic solvents in the total amount of the organic solvent to 1). The organic solvent B has a boiling point of 760 mm Hg. 〇t: an organic solvent having a conductivity of less than 160 ° C and a conductivity of 〇8 nS/cm or more and less than 50 nS/cm at 25 ° C. The organic solvent B may be exemplified by cyclohexanone or propylene glycol-methyl ether B. Acid ester, propylene glycol monomethyl ether, etc. Organic solvent A accounts for 5 of the total amount of organic solvent % Or more less than the amount of

60 weight ° / 〇. When the ratio of the organic solvent A is out of this range, even if it is mixed with the organic agent B, the disadvantage of the prior coating material cannot be sufficiently improved. The organic solvent A is preferably 10% by weight or more and 50% by weight or less based on the total solvent. When the total amount of the organic solvent is used as a standard, the organic solvent B is contained in an amount of 40% by weight or more and less than 5% by weight. When the ratio of the organic solvent B is out of this range, even if it is mixed with the organic solvent A, the disadvantage of the prior coating material cannot be sufficiently improved. The organic solvent B is more preferably 40% by weight or more and 80% by weight or less based on the total solvent. • 11 to 1363930 In the present invention, an organic solvent other than the organic solvents A and B (organic solvent C) can be used. The organic solvent C may, for example, be isoamyl acetate or tripropylene glycol methyl ether. These can be used singly or in combination. When the total amount of the organic solvent is used as a standard, the organic solvent C can be used in a range of not more than 40% by weight.

In Examples 1 to 10, good results were obtained for all of the evaluation items by selecting the preferred organic solvent A' organic solvent B and the type and weight ratio of the organic solvent C. Example 11 Since the organic solvent A did not contain cyclohexanol acetate, slight longitudinal streaks were observed. In Comparative Example 1, since the organic solvent A was not contained, the coating liquid showed a high conductivity of -35 - 1363930 and an I 4 ratio, and as a result, the viscosity was increased with time. Further, the slit portion to which the die was applied was dried and solidified, and longitudinal streaks occurred. In Comparative Examples 2 and 3, since the weight ratio of the organic solvent A was too high, the conductivity rate became low, and a plurality of lateral stripes occurred, and the adhesiveness could not be eliminated. - [Simple diagram] • Sister 〇
