Description

  The present invention resides in a colored resin composition, a color filter, a liquid crystal display device, and an organic EL display device.

Flat panel displays such as liquid crystal display devices and organic EL display devices are widely used, and color filters are used for these displays.
With the trend of energy saving, color filters are required to have higher brightness and higher contrast.
Currently, pigments are mainly used as coloring materials in colored resin compositions for color filters, but in order to obtain high luminance and high contrast in the obtained pixels, for example, in Non-Patent Document 1, pigment particles are used. A method is disclosed in which the particle size is finely dispersed to 1/2 or less of the coloration wavelength. However, in order to achieve the required high brightness and high contrast, it is necessary to perform further atomization, and this causes problems of cost increase and stability after dispersion.

  On the other hand, as a coloring material, development related to a dye has been performed. For example, Patent Document 1 discloses the use of a colored resin composition containing a zinc phthalocyanine pigment and a yellow dye when forming a green pixel. Yes.

Kiyoshi Hashizume, “Color Material Association”, December 1967, p608

However, it has been found that the colored resin composition described in Patent Document 1 may be insufficient for the formation of pixels in spray development.
That is, the colored resin composition described in Patent Document 1 can form an image in immersion development under mild development conditions, but is insufficient for image formation in spray development, which is practically the mainstream. There is a case.

That is, an object of the present invention is to provide a colored resin composition excellent in pixel formation in spray development and having good developability while maintaining or improving the luminance of the obtained pixel.
Another object of the present invention is to provide a color filter using the colored resin composition, a high-quality liquid crystal display device, and an organic EL display device.

As a result of intensive studies by the present inventors, it was speculated that one reason for insufficient pixel formation was that the photopolymerization initiator contained in the composition was not functioning sufficiently.
In a colored resin composition containing a pigment, the absorption wavelength of the pigment overlaps with the absorption wavelength of the photopolymerization initiator, so that the photopolymerization initiator cannot sufficiently obtain light energy, and the amount of radical generation decreases. End up.

Here, in the case of using a dye, particularly a yellow dye, not only the above-mentioned influence but also a radical is generated by contact with the yellow dye even when the photopolymerization initiator is in an excited state upon receiving light energy during development. It has been found that the energy is transferred to the yellow dye before carrying out, and that some photopolymerization initiators do not perform the function of generating radicals.
When the yellow dye is used, the above phenomenon occurs because the yellow dye that exists in a state close to a single molecule is a photopolymerization initiator and a pigment that is associated with the coloring material in the colored tree seed composition. The contact probability is large, and the energy transfer from the photopolymerization initiator is large. Therefore, when a yellow dye is included, it is presumed that the radical generation function of the photopolymerization initiator is not sufficient and the formation of pixels is insufficient as compared with the case of using a pigment.

Furthermore, as a result of intensive studies by the present inventors, in the colored resin composition containing a specific green pigment and a yellow dye, the above problem is solved by the fact that (D) the photopolymerization initiation component contains a specific compound. The present invention was reached upon finding out.
That is, the present invention comprises (A) a metal halide phthalocyanine pigment, (B) a yellow dye, (C) a binder resin, (D) a photopolymerization initiating component and (E) a solvent, The present invention resides in a colored resin composition, a color filter, a liquid crystal display device, and an organic EL display device, wherein the component contains a compound represented by the following formula (1) (hereinafter referred to as “compound (1)”). .

By setting it as the above, the colored resin composition which has favorable dispersion stability and ensured sufficient heat resistance and light resistance can be obtained.

In addition, the average primary particle diameter of a pigment can be calculated | required with the following method. That is, the pigment is ultrasonically dispersed in chloroform, dropped onto a collodion film-attached mesh, dried, and a primary particle image of the pigment is obtained by observation with a transmission electron microscope (TEM). The primary particle diameter is measured from this image, the number average value is calculated according to the following formula, and the average particle diameter is obtained.
In the case of an organic pigment, the particle diameter of each pigment particle was determined for each of a plurality of pigment particles, usually about 200 to 300, with the diameter corresponding to the area circle converted to the diameter of a circle having the same area. Thereafter, the number average value is calculated according to the following formula, and the average particle diameter is obtained.

  The metal halide phthalocyanine pigment thus obtained is dry-ground in a pulverizer such as an attritor, ball mill, vibration mill, vibration ball mill or the like as necessary, and then pigmented by a solvent salt milling method or a solvent boiling method. Thus, a brominated zinc phthalocyanine green pigment that develops a green color with high transmittance and contrast can be obtained. There is no particular limitation on the pigmentation method, but it is preferable to employ the solvent salt milling method in that pigment growth can be easily suppressed and pigment particles having a large specific surface area can be obtained.

[(E) Solvent]
The colored resin composition of the present invention comprises (E) a solvent as an essential component. The solvent has a function of dissolving or dispersing each component contained in the colored resin composition and adjusting the viscosity.
The solvent (E) may be any solvent as long as it can dissolve or disperse each component constituting the colored resin composition, and a solvent having a boiling point in the range of 100 to 200 ° C. is preferably selected. More preferably, it has a boiling point of 120-170 ° C.

Examples of such solvents include the following.

In the solvent, glycol monoalkyl ethers are preferable from the viewpoint of the solubility of the (B) yellow dye. Among these, propylene glycol monomethyl ether is particularly preferable from the viewpoint of the solubility of various components in the composition.
In addition, from the point that the colored resin composition of the present invention contains (A) a halogenated metal phthalocyanine pigment, the balance of applicability, surface tension, etc. is good, and the solubility of the components in the composition is relatively high. It is more preferable to use a mixture of glycol alkyl ether acetates as a solvent. In a composition containing a pigment, glycol monoalkyl ethers have a high polarity, tend to aggregate the pigment, and may reduce storage stability such as increasing the viscosity of the colored resin composition. For this reason, it is preferable that the amount of glycol monoalkyl ethers used is not excessively large. (E) The proportion of glycol monoalkyl ethers in the solvent is preferably 5 to 50% by weight, more preferably 5 to 30% by weight. .

In this case, the content of the high boiling point solvent is preferably 3 to 50% by weight, more preferably 5 to 40% by weight, and particularly preferably 5 to 30% by weight based on the total amount of the solvent (E). If the amount of the high boiling point solvent is too small, for example, a dye component may precipitate and solidify at the tip of the slit nozzle to cause foreign matter defects, and if it is too large, the drying speed of the composition will be slowed down. There is a concern that the filter manufacturing process may cause problems such as tact defects in the vacuum drying process and pin marks of prebaking.
The solvent having a boiling point of 150 ° C. or higher may be glycol alkyl ether acetates or glycol alkyl ethers. In this case, a solvent having a boiling point of 150 ° C. or higher may not be included separately. .

  The colored resin composition of the present invention may be used for color filter production by the ink jet method, but in color filter production by the ink jet method, the ink emitted from the nozzle is very small, from several to several tens pL, There is a tendency for the solvent to evaporate and the ink to concentrate and dry before landing on the periphery of the nozzle opening or in the pixel bank. In order to avoid this, it is preferable that the solvent has a high boiling point. Specifically, it is preferable that the solvent (E) contains a solvent having a boiling point of 180 ° C. or higher. In particular, it is preferable to contain a solvent having a boiling point of 200 ° C. or higher, particularly 220 ° C. or higher. Moreover, it is preferable that the high boiling point solvent whose boiling point is 180 degreeC or more is 50 weight% or more in (E) solvent. When the ratio of such a high boiling point solvent is less than 50% by weight, the effect of preventing evaporation of the solvent from the ink droplets may not be sufficiently exhibited.

  In the colored resin composition of the present invention, the content of the solvent (E) is not particularly limited, but the upper limit is usually 99% by weight. When the content of the solvent (E) in the composition exceeds 99% by weight, the concentration of each component except for the solvent (E) may be too small to be suitable for forming a coating film. . On the other hand, the lower limit of the content of the solvent (E) is usually 75% by weight, preferably 80% by weight, and more preferably 82% by weight in consideration of viscosity suitable for coating.

A preferable acid value of the polyfunctional monomer having an acid group is 0.1 to 40 mg-KOH / g, and particularly preferably 5 to 30 mg-KOH / g.

When it is within the above range, the development and dissolution characteristics are hardly deteriorated, and the production and handling are easy. Furthermore, it is preferable because the photopolymerization performance is hardly lowered and the curability such as the surface smoothness of the pixel is good.
