Description

Laminated body and color filter for color filters {LAMINATED BODY FOR COLOR FILTER AND COLOR FILTER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminate for color filters useful for the formation of color filters for use in liquid crystal display devices (LCDs), solid state imaging devices (CCD, CMOS, etc.), and color filters obtained using the same.

Background Art In recent years, various displays such as televisions, PCs, mobile phones, and the like have been required to have high image quality and high saturation, and particularly for televisions, large screens have also been required. At present, the mainstream of these displays is a liquid crystal display system, and in order to achieve the high image quality, high saturation, and large screen, the technology of the color filter used there is very important. Specifically, it is a technique regarding the process of producing a color filter, the photocurable coloring composition suitable for it, and the laminated body for color filter manufacture formed by apply | coating the layer which consists of a photocurable coloring composition on a support body.

Regarding the high-definition of the color filter, in order to refine the line width of the pattern formation of the color filter, it is necessary to form the pattern with high precision for pattern exposure and subsequent phenomena. In addition, in high saturation, color adjustment, high concentration, etc. of a coloring agent are essential. However, in the curable composition to which a conventional pigment dispersion system is applied, there is a problem that color deviation occurs because the pigment is a relatively coarse particle, and it is difficult to further improve the resolution, and a fine pattern is required like a solid-state imaging device. It was not suitable for the intended use. Then, the technique of using the dye of soluble organic solvent instead of a pigment as a coloring agent is proposed (for example, refer Unexamined-Japanese-Patent No. 2-127602).

Even when using a dye as a coloring agent and using a pigment, it is essential to make content rate of the coloring agent in the colored curable composition for color filter manufacture high. On the other hand, when the content rate of a coloring agent is made high, content of the photoinitiator and photopolymerizable monomer which are components which are necessary in order to harden the said colored curable composition will be restrict | limited, or the exposure wavelength light for an effect will interfere with the glass support interface, etc. Problems tend to occur and high sensitivity of the curable coloring composition and high adhesion to the support are required.

Moreover, in recent years, manufacture of a large area color filter is indispensable with the expansion of the substrate size. However, if the conventional productivity is to be maintained without changing the energy cost in the process, reduction of coating time, exposure time, etc. becomes essential. For this reason, the improvement of the wettability with respect to the glass support of the photocurable coloring agent composition for achieving the quick application | coating speed, and the high sensitivity which can cope with short exposure time (a small exposure amount) are needed.

In addition, in the case of large screen, since the microdefect after manufacturing a color filter largely influences a yield, stabilization at the level higher than the prior art also requires heat resistance, light resistance, etc. of the curable composition which forms a coloring pattern as a result.

Conventionally, as a curable composition for color filter manufacture, the radiation sensitive composition which combined the polyfunctional acrylate, such as a binder polymer containing a carboxyl group, pentaerythritol hexaacrylate, and a photoinitiator, is used, for example, such a radiation As a highly sensitive photoinitiator in a composition, 2,2'-bis (2-chlorophenyl) -4,4 ', 5,5'- tetraphenylbiimidazole and 2,2'-bis (2,3 -Dichlorophenyl) -4,4 ', 5,5'-tetraphenylbiimidazole and the like have been proposed (for example, JP-A-6-75372 and JP-A-6-75373). Reference.).

Moreover, as a photoinitiator which can be applied to a curable composition, it is a photoinitiator which can be applied to the radiation sensitive composition used for a printing plate and a photoresist, A 2,2'-bis (2-chlorophenyl) -4,4 ', 5 , 5'-tetraphenylbiimidazole, 2,2'-bis (2-chlorophenyl) -4,4 ', 5,5'-tetra (alkoxyphenyl) biimidazole, 2,2'-bis (2 -Chlorophenyl) -4,4 ', 5,5'-tetra (dialkoxyphenyl) biimidazole, 2,2'-bis (2-chlorophenyl) -4,4', 5,5'-tetra ( Trialkoxyphenyl) biimidazole and the like have been proposed (see, for example, Japanese Patent Laid-Open No. 48-38403 and Japanese Patent Laid-Open No. 62-174204).

However, with respect to any of the above curable compositions, the sensitivity is not yet at a satisfactory level, and it is necessary to irradiate high energy radiation in curing. In the case where the colored pattern of the color filter is formed using such a curable composition, if the irradiation amount is insufficient, problems such as missing or missing patterns, residual film ratio, or decrease in pixel intensity may occur, and further, the colored pattern of the obtained color filter A problem arises in that the resolution and the adhesiveness of the support deteriorate.

As mentioned above, even if it contains a coloring agent in high concentration, it is hardened with high sensitivity and is excellent in the adhesiveness of the color filter laminated body provided with the colored curable composition layer which has favorable pattern formation property, and the resolution and support obtained using it. Although the color filter provided with the coloring pattern is calculated | required, it is the present situation which is not provided yet.

<Glass formed by float method or down draw method>

First, the glass formed by the float method or the down-draw method used as a support body of the laminated body for color filters is demonstrated.

Glass is generally classified into A) soda-lime glass (soda glass), B) borosilicate glass, C) lead glass, and D) other oxide glass by the material composition to comprise.

A) Soda-lime glass is easy to mold, has excellent chemical durability, and is easy and inexpensive to obtain raw materials. It is used for flat glass and bottle glass. B) Borosilicate glass is a glass incorporating borax B ₂ O ₃ into a material, and is used as a low-expansion glass that is a glass for touch panels, pyrex (registered trademark) for chemical experiments, heat resistant glass for mercury lamps or glass tubes. C) Lead glass contains lead oxide and is used as crystal glass, high refractive glass for optical lenses, and radiation shielding glass for CRT. D) As other oxide glass, there are aluminosilicate glass which is excellent in water resistance, borate glass used as a solder for glass bonding, phosphate glass used for artificial bones, etc.

Especially, the aluminosilicate glass which is A) soda-lime glass and D) other oxide glass is manufactured preferably by the float method and the down-draw method.

In particular, aluminosilicate glass has excellent damage resistance to ordinary soda lime glass.

Although the glass base material used for this invention can be used as long as it is the glass manufactured by the float method and the downdraw method, As mentioned above, from the viewpoint of improving the damage resistance, dimensional precision, and smoothness of tempered glass, It is an aluminosilicate glass, and what was manufactured by the float method and the downdraw method is preferable.

EMBODIMENT OF THE INVENTION Hereinafter, the preferable composition of the glass which is preferably used for this invention and is manufactured preferably by the float method and the downdraw method is demonstrated.

An example of such glass, for example, by weight% is preferably used for aircraft is described in International Publication No. WO / 94/08910 (PCT / FR93 / 01035) _{Brochure, SiO 2: 65.0 ~ 76.0%} , Al 2 O 3 : 1.5 to 50.0%, MgO: 4.0 to 8.0%, CaO: 0.0 to 4.5%, Na ₂ O: 10.0 to 18.0%, K ₂ O: 1.0 to 7.5%, B ₂ O ₃ : 0.0 to 4.0% of glass, Japanese Patent Publication No. a single glass sheet which is preferably used in the laminated glass described in 11-11988 No.,% by weight of the composition is _{SiO 2: 58 ~ 66%,} Al 2 O 3: 13 ~ 19%, Li ₂ O: 3 to 4.5%, Na ₂ O: 6 to 13%, K ₂ O: 0 to 5%, R ₂ O 10 to 18% (where R ₂ O = Li ₂ O + Na ₂ O + K ₂ O), MgO: 0-3.5%, CaO: 1-7%, SrO: 0-2%, BaO: 0-2%, RO: 2-10% (RO = MgO + CaO + SrO + BaO ), TiO ₂ : 0 ~ 2%, CeO ₂ : 0 ~ 2%, Fe ₂ O ₃ : 0 ~ 2%, MnO: 0 ~ 1%, (TiO ₂ + CeO ₂ + Fe ₂ O ₃ + MnO = 0.01-3%) of the aluminosilicate glass composition,

Natanaeseo in weight percent of the glass _{composition, SiO 2: 60 ~ 66%} , Al 2 O 3: 15 ~ 18%, Li 2 O: 3 ~ 4.5%, Na 2 O: 7.5 ~ 12.5%, K 2 O: 0 ~ 2% (Li ₂ O + Na ₂ O + K ₂ O = 11-17%), MgO: 0.5-3%, CaO: 2.5-6%, SrO: 0-2%, BaO: 0-2% (MgO + CaO + SrO + BaO = 3 to 9%), TiO ₂ : 0 to 2%, CeO ₂ : 0 to 2%, Fe ₂ O ₃ : 0 to 2%, MnO: 0 to 1% ( However, TiO ₂ + CeO the like _{2 + Fe 2 O 3 + MnO} = 0.01 aluminosilicate glass composition of 2-3%) is preferred.

Although mix | blending of a glass composition can be suitably selected according to the purpose of use of the tempered glass of this invention, the support of the selection of each component in that case is demonstrated below.

First, as for the main component of the glass may be mentioned SiO _2, it is an essential ingredient. Generally, the ratio is 58%-66% of range, favorable water resistance is obtained, the viscosity of a glass melt is appropriately maintained, and melting and shaping | molding can be performed with good workability. As a result, 58 ~ 66% is preferable as the range of SiO _2, more preferably 60 ~ 66%.

Al ₂ O ₃ is also one of the important constituents of glass. By containing Al ₂ O ₃ improves the water resistance, but when added in large quantities, since the viscosity is enhanced, from the viewpoint not to obtain a sufficient effect, lowering the work efficiency 13-19%, far preferably from 15 to 19%, more preferably Do.

Li ₂ O is a component that improves solubility, but when excessively added, water resistance deteriorates, the liquidus temperature rises, and molding tends to be difficult. As a result, 3 to 4.5% is preferable as the range of the Li ₂ O.

Na ₂ O is a component that increases solubility, and from the viewpoint of curing, the content is preferably 6 to 13%, more preferably 7.5 to 12.5%.

K ₂ O is also a component that enhances solubility. As the range of the K ₂ O is not more than 5% or less is preferable, and 2% is more preferred.

Further, the three components are all components to increase the solubility, such a point of view, it is the sum of _{Li 2 O + Na 2 O +} K 2 O R 2 O is more preferably from 9 to 18% preferably 10 to 17%.

Although MgO is a component which improves solubility, when added excessively, liquidus temperature will become high and it will become difficult to shape | mold. For this reason, 3.5% or less is preferable and, as for content of MgO, 0.5-3% is more preferable.

CaO also has the same function as MgO, and the addition amount is preferably 1 to 7%, more preferably 2.5 to 6%.

SrO and BaO are the components that increase the solubility and are effective for lowering the liquidus temperature. However, while the density of the glass increases, it becomes a factor of the rise of the raw material zone. For this reason, 2% or less is preferable respectively, and 1% or less of SrO and BaO is more preferable.

Moreover, when the sum total of MgO + CaO + SrO + BaO is RO, it is 2-10% as a range of RO from a viewpoint of maintaining the viscosity of a glass melt and the range of liquidus temperature suitably, and achieving favorable melting and moldability. Is preferable and 3 to 9% is more preferable.

In Fe ₂ O ₃ , Fe ²⁺ and Fe ³⁺ are in an equilibrium state in the glass melt, and these ions greatly influence the transmittance of light in the melt, particularly the transmittance in the infrared region. When the total iron is converted into Fe ₂ O ₃ , the absorption of the infrared region becomes too large at 2% or more, which makes it impossible to control the temperature distribution of the glass at the time of melting or forming, resulting in deterioration of quality. Therefore, total iron is preferably less than 2% as Fe ₂ O _3.

TiO ₂ , CeO ₂ and MnO are effective components for changing the equilibrium state of Fe ²⁺ and Fe ³⁺ and interacting to change the light transmittance. However, excessively containing the glass deteriorates quality and leads to an increase in the raw material cost. Therefore, the range of 3% or less As the TiO ₂ is preferred, and more preferably less than 2%. Further, as the range of CeO ₂ is less than 2% is preferred. As the range of MnO, 1% or less is preferable.

In addition to the above components, in the glass composition, other components, for example, colorants such as NiO, Cr ₂ O ₃ , CoO, SO ₃ , As ₂ O ₃ , Sb ₂ O _3, etc., in a range that does not impair the desired properties. And clarifiers.

SO ₃ originates from the sulfate used as a clarifier, and when sulphate is used for the clarifier, the effect of clarification is obtained by setting the residual amount in glass to 0.05% or more, but the effect of clarification even if the residual amount exceeds 0.5% it is equivalent, and also they add to the sO _x contained in the exhaust gas at the time of melting glass, Environmental Award undesirable. Therefore, it is SO ₃ is preferably 0.05% ~ 0.5% remained in the glass.

In general, As ₂ O ₃ and Sb ₃ O ₃ used as clarifiers are preferably 1% or less from the toxicity, and are preferably at most 0.1% or less mixed with impurities.

In addition, the highly volatile B ₂ O ₃ , ZnO, P ₂ O ₅ , PbO and the like erode the edges of the glass melting furnace, and the volatile components are agglomerated to the ceiling of the furnace and fall on the glass together with the edges. In order to make it worse, it is preferable to make it into the amount incorporating from an impurity less than 0.1%.

Since the glass plate formed by the float method is excellent in smoothness, post-processing, such as grinding | polishing, is unnecessary, and a large platelet can also be obtained in size at low cost. Moreover, in the float method, since the glass base melted at the time of shaping | molding of a glass is conveyed on a molten tin bus, it develops and shape | molds, the stress in a glass is released | released well. From this point of view, there is a feature that cracks are less likely to enter the glass due to impact or the like compared to other manufacturing methods.

In addition, the downdraw method is a method of forming a glass plate by using air as a coolant, and since it is a non-contact molding, there is no fear of mixing of impurities due to the frame, and it has excellent smoothness, high purity and thin glass sheet. Since it can be used, it is used preferably for displays, such as a liquid crystal display device. The shaping | molding method of the glass by the down-draw method is described in detail in Unexamined-Japanese-Patent No. 5-163032, Unexamined-Japanese-Patent No. 2002-167226, etc., for example, The glass obtained by the method as described also also in this invention. It can be used preferably.

In order to melt | dissolve high quality glass, the viscosity of glass is preferable that melting temperature, ie, the temperature which has the viscosity of 10 ² poise, is 1550 degrees C or less, and 1540 degrees C or less is more preferable. In addition, in order to form a glass composition by the float method for the purpose of shaping | molding to a sheet shape of high flatness, it is preferable that the temperature which has the viscosity of a working temperature, ie, 10 ⁴ poise, is 1100 degrees C or less, and the liquidus temperature is below the working temperature, It is more preferable that the working temperature is 1055 ° C or less, and the liquidus temperature is below the working temperature.

By using aluminosilicate glass and soda-lime glass produced by the float method and the down-draw method especially, favorable interaction with each component in the photocurable colored layer composition which forms the photocurable colored layer mentioned later is formed.

That is, since the float method and the down-draw method provide glass with high surface smoothness, uniform application | coating of the coating liquid for photocurable colored layer formation in the photocurable colored layer formation process at the time of forming the laminated body of this invention is uniform. In addition, the laminated body of a large area can be manufactured efficiently, and the glass obtained by this manufacturing method has a density of silanol groups on the surface in terms of the component ratio and crystal structure of aluminosilicate glass and soda lime glass. Due to the high activity and the formation of desirable interactions with the constituents of the photocurable colored layer, the use of such a glass substrate increases the adhesion efficiency with the colored layer after the photocuring reaction, thereby improving high adhesion, light resistance and heat resistance. It is thought to contribute.

Although the thickness of the glass plate as a base material is suitably selected according to the use purpose of a color filter, it is generally the range of 0.3-2.0 mm, and it is preferable that it is 0.5-8.0 mm from a viewpoint of transparency and intensity | strength.

As said mass ratio, the range of 100: 30-100: 120 is especially preferable.

As a blue pigment, a phthalocyanine type pigment can be used individually, or the mixture of this and a dioxazine type purple pigment can be used. For example, a mixture of C.I.

It is preferable to perform exposure by irradiation of radiation, and especially ultraviolet rays, such as g line | wire and i line | wire, are preferably used as radiation which can be used at the time of exposure, and a high pressure mercury lamp is used more preferably. 5mJ / cm <2> -1500mJ / cm <2> is preferable, 10mJ / cm <2> -1000mJ / cm <2> is more preferable, and 10mJ / cm <2> -800mJ / cm <2> is the most preferable.

Development Process

Following an exposure process, alkali image development process is performed and the tailing irradiation part in an exposure process is eluted to an alkali aqueous solution. This leaves only the photocured portion.

As a developing solution, the organic alkali developing solution which does not cause damage to a circuit of an underlayer etc. is preferable. As image development temperature, it is 20 degreeC-30 degreeC normally, and developing time is 20 to 90 second.

As an alkali used for a developing solution, for example, ammonia water, ethylamine, diethylamine, dimethylethanolamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, choline, pyrrole, piperidine, 1,8-dia An alkaline aqueous solution obtained by diluting an organic alkaline compound such as xabicyclo- [5,4,0] -7-undecene with a pure water so as to have a concentration of 0.001 to 10% by mass, preferably 0.01 to 1% by mass is used. In addition, when the developing solution which consists of such alkaline aqueous solution is used, generally it wash | cleans (rinses) with pure water after image development.

Moreover, in the manufacturing method of this invention, even after performing the curable composition layer formation process, exposure process, and image development process mentioned above, the hardening process which hardens the formed coloring pattern by heating and / or exposure as needed is included. good.

Thereafter, a photocurable colored layer having a different color is formed, and the exposure step and the developing step (and curing step, if necessary) are repeated by a desired number of colors, whereby a color filter having a desired color is produced.

Since the color filter of this invention is produced using the laminated body of a specific glass support body and the layer which consists of the composition for colored layers which concerns on this invention, it is excellent in pattern formation property, and the formed coloring pattern shows high adhesiveness with a support substrate. Since the hardened | cured composition is excellent in light resistance and developability, it is excellent in exposure sensitivity, the adhesiveness with the board | substrate of an exposure part is favorable, and the high resolution pattern which gives a desired cross-sectional shape can be formed. Therefore, it can be used suitably for solid-state image sensors, such as a liquid crystal display element and CCD, and is especially preferable for a CCD element, CMOS, etc. of high resolution exceeding 1 million pixels. The color filter of this invention can be used as a color filter arrange | positioned, for example between the light receiving part of each pixel which comprises CCD, and the microlens for condensing.
