Description
本発明は、光学フィルムに使用されるレターデーション上昇剤、及びそれを含有するセルロース系樹脂組成物、該セルロース系樹脂組成物から得られるフィルムに関する。 The present invention relates to a retardation increasing agent used for an optical film, a cellulose resin composition containing the same, and a film obtained from the cellulose resin composition.
近年、映像や文字を鮮明に表示できる液晶表示装置を備えたノートパソコンやテレビ等の情報機器が次々と市場に供給されている。これらの情報機器に対する消費者の要望として、高機能性付与の他に、住環境の多様化に応じられるような省スペース化等があり、これらのニーズに応える上で、情報機器の薄型化や軽量化、大画面化に伴う高視野角や高コントラストなどが求められている。 In recent years, information devices such as notebook computers and televisions equipped with a liquid crystal display device capable of clearly displaying images and characters have been supplied to the market one after another. Consumer demand for these information devices includes, in addition to imparting high functionality, space saving to meet diversification of the living environment. To meet these needs, information devices can be made thinner and thinner. High viewing angles, high contrast, and the like associated with lighter weight and larger screens are required.
情報機器の薄型化は、情報機器に備えられている液晶表示装置の奥行きを薄くする事に依存する。液晶表示装置は、概略として２枚のガラス基板の間に電極からなる層と液晶物質からなる層とを有する積層構造体から構成される。前記ガラス基板は液晶層とは反対側の面に偏光子が添付されており、この偏光子としては、通常、ポリビニルアルコールからなる偏光子の両面に保護フィルムを貼付したものが使用されている。前記偏光子保護フィルムは、一般的に透明性が高く、適度な強度を有しており、かつポリビニルアルコールとの接着性に優れるものとしてセルロースエステル系樹脂フィルムが使用されている。 Thinning of information equipment depends on reducing the depth of a liquid crystal display device included in the information equipment. The liquid crystal display device is generally composed of a laminated structure having a layer made of an electrode and a layer made of a liquid crystal substance between two glass substrates. The glass substrate has a polarizer attached to the surface opposite to the liquid crystal layer. As the polarizer, one having a protective film attached to both sides of a polarizer made of polyvinyl alcohol is usually used. As the polarizer protective film, a cellulose ester-based resin film is generally used as a film having high transparency, moderate strength, and excellent adhesion to polyvinyl alcohol.
一方、液晶表示装置の高視野角化に寄与するために、セルロースエステル系樹脂フィルムに光学補償能を付与することが求められている。しかし、セルロースエステル系樹脂フィルムはそのままでは光学補償フィルムに必須なレターデーション（複屈折性）が十分ではないため、セルロースエステル系樹脂フィルムにレターデーションを付与するさまざまな検討がなされてきている。近年、液晶テレビのさらなる視野角拡大や薄膜化のために、より大きなレターデーションが求められている。 On the other hand, in order to contribute to an increase in viewing angle of a liquid crystal display device, it is required to impart optical compensation ability to the cellulose ester resin film. However, since the cellulose ester resin film as it is does not have sufficient retardation (birefringence) for the optical compensation film, various studies have been made to impart retardation to the cellulose ester resin film. In recent years, a larger retardation has been demanded for further widening the viewing angle and thinning of liquid crystal televisions.
樹脂フィルムのレターデーションを増加させるため、レターデーション上昇剤を添加する方法が知られているが、これまでのレターデーション上昇剤では多量添加が必要となりブリードアウトなどの問題が発生するため、実用化が困難であった。また、セルロースの総アシル基置換度を低下させる方法なども提案されているが、吸湿性が増加したりするなどの問題があって、やはり実用化は難しかった。 In order to increase the retardation of the resin film, a method of adding a retardation increasing agent is known. However, the conventional retardation increasing agent needs to be added in a large amount and causes problems such as bleed out. It was difficult. Also, a method for reducing the total acyl group substitution degree of cellulose has been proposed, but it has been difficult to put it to practical use due to problems such as an increase in hygroscopicity.
例えば特許文献１には、フェノール性水酸基を有する多環芳香族化合物をレターデーション上昇剤として使用してなるセルロースエステルフィルムが提案されているが、相溶性が不十分であるため光学特性向上効果が不十分であった。また特許文献２、３には特定の芳香族化合物からなるレターデーション向上剤が記載され、２−フェニル−４Ｈ−１−ベンゾピラン−４−オンの記載もあるが、これのレターデーション上昇効果は不十分であった。 For example, Patent Document 1 proposes a cellulose ester film using a polycyclic aromatic compound having a phenolic hydroxyl group as a retardation increasing agent. However, since the compatibility is insufficient, the effect of improving optical properties is improved. It was insufficient. Patent Documents 2 and 3 describe a retardation improver composed of a specific aromatic compound, and there is also a description of 2-phenyl-4H-1-benzopyran-4-one, but this does not increase the retardation effect. It was enough.
従って、本発明の目的は、相溶性に優れ、ブリードアウト等を生じることなく、高いレターデーション値をフィルムに付与することができるレターデーション上昇剤を提供すること、また該レターデーション上昇剤を含有するセルロースエステル系樹脂組成物を提供すること、また該セルロース系樹脂組成物から得られる、優れた光学特性を有するフィルムを提供することにある。 Accordingly, an object of the present invention is to provide a retardation increasing agent that is excellent in compatibility and can give a high retardation value to a film without causing bleed out or the like, and also contains the retardation increasing agent. An object of the present invention is to provide a cellulose ester-based resin composition, and to provide a film having excellent optical properties obtained from the cellulose-based resin composition.
なお、本発明において優れた光学特性を有するフィルムとは、大きなレターデーションが付与されたフィルムを意味する。このレターデーションは、フィルムの厚み方向のレターデーション値（Ｒｔｈ）によって把握することが可能である。
Ｒｔｈは下記式で定義される値である。
Ｒｔｈ＝｛（ｎｘ＋ｎｙ）／２−ｎｚ｝×ｄ
［式中、ｎｘはフィルム面内の屈折率が最も大きい方向の屈折率、ｎｙは前記屈折率が最も大きい方向に直角な方向のフィルム面内の屈折率、ｎｚはフィルムの厚み方向の屈折率、ｄはフィルムの厚み（ｎｍ）を表す。］
In the present invention, the film having excellent optical characteristics means a film having a large retardation. This retardation can be grasped by the retardation value (Rth) in the thickness direction of the film.
Rth is a value defined by the following formula.
Rth = {(nx + ny) / 2−nz} × d
[Where nx is the refractive index in the direction with the largest refractive index in the film plane, ny is the refractive index in the film plane in the direction perpendicular to the direction with the largest refractive index, and nz is the refractive index in the thickness direction of the film. , D represents the thickness (nm) of the film. ]
上記レターデーション値Ｒｔｈは、例えば、ＫＯＢＲＡ−ＷＲ（王子計測機器（株）製）やＲＥＴＳ−１００（大塚電子（株）製）などの自動複屈折率計を用いて測定することができる。 The retardation value Rth can be measured using an automatic birefringence meter such as KOBRA-WR (manufactured by Oji Scientific Instruments) or RETS-100 (manufactured by Otsuka Electronics Co., Ltd.).
本発明者らは、上記課題を解決すべく鋭意検討した結果、優れたレターデーション上昇効果を有する化合物を見出し、本発明を完成するに至った。 As a result of intensive studies to solve the above problems, the present inventors have found a compound having an excellent retardation increasing effect, and have completed the present invention.

Flame retardants, fluorescent agents, antifungal agents, bactericides, metal deactivators, mold release agents, pigments, processing aids, antioxidants, light stabilizers, foaming agents and the like can be blended.
次に、本発明のセルロース系樹脂組成物からフィルムを製造する方法について説明する。
該フィルムの製造は、セルロース系樹脂組成物を溶剤に溶解させたドープ液を塗布、乾燥して行われる。ドープ液には必要に応じて各種添加剤を混合することができる。ドープ液中のセルロース系樹脂の濃度は、濃い方が支持体に流延した後の乾燥負荷が低減できて好ましいが、セルロース系樹脂の濃度が濃過ぎると濾過時の負荷が増えて、濾過精度が悪くなる。これ等を両立する濃度としては、１０〜３０質量％が好ましく、更に好ましくは１５〜２５質量％である。
Next, a method for producing a film from the cellulose resin composition of the present invention will be described.
The film is produced by applying and drying a dope solution obtained by dissolving a cellulose resin composition in a solvent. Various additives can be mixed in the dope liquid as necessary. The concentration of cellulosic resin in the dope solution is preferably higher because the drying load after casting on the support can be reduced. However, if the concentration of cellulosic resin is too high, the load during filtration increases and the filtration accuracy increases. Becomes worse. As a density | concentration which makes these compatible, 10-30 mass% is preferable, More preferably, it is 15-25 mass%.
本発明に係るドープ液の調製に用いる溶剤は、１種単独でもよく、２種以上の併用でもよいが、セルロース系樹脂の良溶剤と貧溶剤とを混合して用いることが生産効率の点で好ましい。良溶剤と貧溶剤の混合比率の好ましい範囲は、良溶剤が７０〜９８質量％であり、貧溶剤が３０〜２質量％である。本発明に用いられる良溶剤、貧溶剤については、使用するセルロース系樹脂を単独で溶解するものを良溶剤、単独では膨潤するのみかあるいは溶解し得ないものを貧溶剤と定義する。そのため、セルロース系樹脂の平均酢化度によっては、良溶剤、貧溶剤が変わり、例えば、アセトンは、平均酢化度５５％のセルロース系樹脂では良溶剤になり、平均酢化度６０％のセルロース系樹脂では貧溶剤となってしまう。このように、良溶剤、貧溶剤はすべての場合に一義的に決まるものではない。本発明において好ましいセルロース系樹脂であるセルローストリアセテートの場合には、良溶剤としては、メチレンクロライド等の有機ハロゲン化合物やジオキソラン類が挙げられ、また、セルロースアセテートプロピオネートの場合にはメチレンクロライド、アセトン、酢酸メチル等が挙げられる。一方、これらの場合、貧溶剤としては、例えば、メタノール、エタノール、ｎ−ブタノール、シクロヘキサン、シクロヘキサノン等が挙げられる。 The solvent used for the preparation of the dope liquid according to the present invention may be used alone or in combination of two or more. However, it is possible to use a mixture of a good solvent and a poor solvent of cellulose resin in terms of production efficiency. preferable. The preferable range of the mixing ratio of the good solvent and the poor solvent is 70 to 98% by mass for the good solvent and 30 to 2% by mass for the poor solvent. Regarding the good solvent and the poor solvent used in the present invention, those that dissolve the cellulose resin used alone are defined as good solvents, and those that only swell or cannot be dissolved alone are defined as poor solvents. Therefore, depending on the average degree of acetylation of the cellulose resin, the good solvent and the poor solvent change. For example, acetone becomes a good solvent in a cellulose resin having an average degree of acetylation of 55%, and cellulose having an average degree of acetylation of 60%. It becomes a poor solvent in the system resin. Thus, the good solvent and the poor solvent are not uniquely determined in all cases. In the case of cellulose triacetate which is a preferred cellulose resin in the present invention, examples of the good solvent include organic halogen compounds such as methylene chloride and dioxolanes, and in the case of cellulose acetate propionate, methylene chloride and acetone. And methyl acetate. On the other hand, in these cases, examples of the poor solvent include methanol, ethanol, n-butanol, cyclohexane, and cyclohexanone.
上記ドープ液を調製するときのセルロース系樹脂の溶解方法としては、一般的な方法を用いることができるが、加圧下で、溶剤の常圧での沸点以上でかつ溶剤が沸騰しない範囲の温度で加熱し、撹拌しながら溶解する方法が、ゲルやママコと呼ばれる塊状未溶解物の発生を防止することができるため、好ましい。また、セルロース系樹脂を貧溶剤と混合し、湿潤あるいは膨潤させた後、さらに良溶剤と混合して溶解する方法も好ましく用いられる。さらに、公知の冷却溶解法を用いてもよい。冷却溶解法を用いる場合には、良溶剤として酢酸メチル、アセトンを用いることができる。加圧は、窒素ガス等の不活性気体を圧入する方法や、加熱による溶剤の蒸気圧の上昇によって行ってもよい。加熱は、外部から行うことが好ましく、例えば、ジャケットタイプのものは温度コントロールが容易であるため、好ましい。 As a method for dissolving the cellulose-based resin when preparing the dope solution, a general method can be used, but under pressure, at a temperature not lower than the boiling point at the normal pressure of the solvent and in a range where the solvent does not boil. A method of heating and stirring while stirring is preferable because it can prevent the generation of massive undissolved material called gel or mamako. Further, a method in which a cellulose resin is mixed with a poor solvent and wetted or swollen and then mixed with a good solvent and dissolved is also preferably used. Furthermore, a known cooling dissolution method may be used. When the cooling dissolution method is used, methyl acetate or acetone can be used as a good solvent. The pressurization may be performed by a method of injecting an inert gas such as nitrogen gas or by increasing the vapor pressure of the solvent by heating. Heating is preferably performed from the outside. For example, a jacket type is preferable because temperature control is easy.
溶剤を添加した後の加熱温度は、使用溶剤の常圧での沸点以上で、かつ溶剤が沸騰しない範囲の温度が、セルロース系樹脂の溶解度の観点から好ましい。加熱温度が高過ぎると必要とされる圧力が大きくなり、生産性が悪くなる。好ましい加熱温度の範囲は４５〜１２０℃であり、６０〜１１０℃がより好ましく、７０〜１０５℃が更に好ましい。また、圧力は、設定温度で溶剤が沸騰しないように調整する。加熱後は、得られたセルロース系樹脂溶液を濾紙等の適当な濾材を用いて濾過する。濾材としては、不要物等を除去するために絶対濾過精度が小さい方が好ましいが、絶対濾過精度が小さ過ぎると濾材の目詰まりが発生しやすいという問題点が生じる。このため、絶対濾過精度０．００８ｍｍ以下の濾材が好ましく、０．００１〜０．００８ｍｍの範囲の濾材がより好ましく、０．００３〜０．００６ｍｍの範囲の濾材が更に好ましい。濾材の材質は特に制限はなく、通常の濾材を使用することができるが、例えば、ポリプロピレン、テフロン（登録商標）等のプラスチック製の濾材やステンレス等の金属製の濾材が繊維の脱落等がなく、好ましい。 The heating temperature after addition of the solvent is preferably a temperature that is not less than the boiling point of the solvent used at normal pressure and that the solvent does not boil from the viewpoint of the solubility of the cellulose resin. If the heating temperature is too high, the required pressure increases and productivity decreases. The range of preferable heating temperature is 45-120 degreeC, 60-110 degreeC is more preferable, and 70-105 degreeC is still more preferable. The pressure is adjusted so that the solvent does not boil at the set temperature. After heating, the obtained cellulose resin solution is filtered using an appropriate filter medium such as filter paper. As the filter medium, it is preferable that the absolute filtration accuracy is small in order to remove unnecessary substances and the like, but if the absolute filtration accuracy is too small, there is a problem that the filter medium is likely to be clogged. For this reason, a filter medium having an absolute filtration accuracy of 0.008 mm or less is preferable, a filter medium in the range of 0.001 to 0.008 mm is more preferable, and a filter medium in the range of 0.003 to 0.006 mm is still more preferable. The material of the filter medium is not particularly limited, and a normal filter medium can be used. For example, a filter medium made of plastic such as polypropylene and Teflon (registered trademark) or a metal filter medium such as stainless steel does not lose fibers. ,preferable.
ドープ液の濾過は通常の方法で行うことができるが、加圧下で、溶剤の常圧での沸点以上でかつ溶剤が沸騰しない範囲の温度で加熱しながら濾過する方法が、濾材前後の差圧（以下、濾圧ということがある）の上昇が小さく、好ましい。好ましい濾過の温度は４５〜１２０℃であり、４５〜７０℃がより好ましく、４５〜５５℃が更に好ましい。濾圧は小さい方が好ましい。濾圧は１．６×１０６Ｐａ以下であることが好ましく、１．２×１０６Ｐａ以下であることがより好ましく、１．０×１０６Ｐａ以下であることが更に好ましい。 The dope solution can be filtered by a normal method, but the method of filtering while heating at a temperature not lower than the boiling point of the solvent at a normal pressure and in a range where the solvent does not boil is a differential pressure before and after the filter medium. An increase in (hereinafter sometimes referred to as filtration pressure) is small and preferable. The temperature of preferable filtration is 45-120 degreeC, 45-70 degreeC is more preferable, and 45-55 degreeC is still more preferable. A smaller filtration pressure is preferred. The filtration pressure is preferably 1.6 × 10 6 Pa or less, more preferably 1.2 × 10 6 Pa or less, and further preferably 1.0 × 10 6 Pa or less.
フィルムの膜厚は、薄い方が液晶ディスプレイの薄型化が容易になるため好ましいが、薄過ぎると、透湿度が増大し、引き裂き強度等が不足する。これ等を両立するセルロース系樹脂フィルムの膜厚としては、１０〜１５０μｍが好ましく、２０〜１００μｍがより好ましい。 A thinner film is preferable because it makes it easier to reduce the thickness of the liquid crystal display. However, if the film is too thin, the moisture permeability increases and the tear strength and the like are insufficient. As a film thickness of the cellulose resin film which makes these compatible, 10-150 micrometers is preferable and 20-100 micrometers is more preferable.
