Definitions
- the present invention relates to a mixture having a specific value of YI / ⁇ n, a composition containing the mixture, a polymer obtained by polymerizing the polymerizable composition, and an optical obtained by polymerizing the polymerizable composition.
- the present invention relates to an anisotropic body and a retardation film obtained by polymerizing the polymerizable composition, and also relates to a display device, an optical element, a light emitting device, a printed material, an optical information recording device, etc. having the optical anisotropic body. .
- Compounds having mesogenic groups are used for various optical materials. For example, it is possible to produce a polymer having a uniform orientation by aligning a polymerizable composition containing a compound having a mesogenic group in a liquid crystal state and then polymerizing the polymer composition (Patent Document 1). Such a polymer can be used for polarizing plates, retardation plates and the like necessary for displays. In many cases, two or more mesogens are required to meet the required optical properties, polymerization rate, solubility, melting point, glass transition temperature, polymer transparency, mechanical strength, surface hardness, heat resistance and light resistance. A polymerizable composition containing a compound having a group is used. At that time, the compound having a mesogenic group to be used is required to bring good physical properties to the polymerizable composition without adversely affecting other properties.
- the brightness of the screen may be uneven or the color may be unnatural, or the desired optical characteristics may not be obtained, and the quality of the display product There is a problem that greatly reduces. Therefore, there has been a demand for the development of a compound having a mesogenic group having reverse wavelength dispersion or low wavelength dispersion that can solve such problems.
- the problem to be solved by the present invention is that when a film-like polymer is prepared by adding it to the polymerizable composition, the film-like polymer is hardly repelled, and when the obtained film-like polymer is irradiated with ultraviolet light,
- An object of the present invention is to provide a polymerizable composition that is less prone to orientation defects. Furthermore, it is providing the polymer obtained by polymerizing the said polymeric composition, and the optical anisotropic body using the said polymer.
- the present invention contains an inverse wavelength dispersive or low wavelength dispersible compound having at least one mesogenic group, and has the following formula (formula 1) 0.5 ⁇ YI / ⁇ n ⁇ 500 (Formula 1) (Wherein YI represents the yellowness of the compound and ⁇ n represents the refractive index anisotropy at a wavelength of 550 nm when the film is formed), a composition containing the mixture, A coalescence, an optical anisotropic body, and a retardation film are provided.
- the mixture of the present invention hardly causes repelling when the composition is made to produce an optical anisotropic body.
- an optical anisotropic body using the composition containing the mixture of the present invention is useful for the use of optical materials such as a retardation film because alignment defects are less likely to occur when irradiated with ultraviolet light.
- the “mixture” refers to a reverse wavelength dispersive or low wavelength dispersible compound having at least one mesogenic group (hereinafter referred to as a compound having a mesogenic group) and a compound having a mesogenic group. It contains impurities that are inevitably mixed.
- An impurity means components other than the compound which has a mesogenic group in a mixture.
- a compound having a mesogenic group is produced through a purification process, but it is difficult to completely eliminate impurities even after the purification process. Contains not a few impurities.
- the present invention is referred to as a “mixture” in order to clearly distinguish the compound containing impurities in this way from the compound itself containing no impurities.
- the mixture contains impurities, but the content of the compound in the mixture is 70.0% by mass or more, preferably 80.0% by mass or more, and more preferably 85.0% by mass or more. 90.0% by mass or more is particularly preferable.
- the “composition” includes one or more of the above-mentioned mixtures, and if necessary, a compound not containing a mesogenic group, a stabilizer, an organic solvent, a polymerization inhibitor, an antioxidant. Agent, photopolymerization initiator, thermal polymerization initiator, surfactant and the like.
- the mixture of the present invention consists of a compound having a single mesogenic group and impurities
- the composition of the present invention contains one mixture and one or more additives. It is distinguished in that it contains two or more kinds of mixtures and, if necessary, additives.
- the polymerizable composition may be referred to as a polymerizable liquid crystal composition.
- liquid crystal refers to a method in which the polymerizable composition is applied to a substrate, printed, dropped, or injected into a cell.
- the composition is intended to exhibit liquid crystallinity, and the composition may not necessarily exhibit liquid crystallinity.
- Impurities are removed from the mixture by the purification process, but there is a problem that the yield deteriorates through the purification process.
- the cause it is considered that the compound is removed together with impurities in the mixture through the purification step, and the compound is adsorbed by the purification agent.
- the purification process a large amount of the compound is taken into the impurity, or when the mixture contains a compound having a polymerizable group, the polymer components of the impurity contained in a trace amount in the mixture gather together. It is also possible that the filtration is complicated.
- the yellowness (YI) of the mixture of the present invention When the yellowness (YI) of the mixture of the present invention is measured, the more purified the mixture, the lower the yellowness value.
- the present inventors paid attention to a mixture containing a compound having a mesogenic group, and as a result of extensive studies, the values of the yellowness (YI) of the mixture and the refractive index anisotropy ( ⁇ n) of the compound are related to the yield. I found that there is sex.
- the present inventors further examined the yellowness (YI) of the mixture and the values of the refractive index anisotropy ( ⁇ n) of the compound, and these values are the repulsion when a composition containing the mixture is applied to a substrate. It has been found that this has an effect on orientation defects when the composition is used as an optically anisotropic substance and irradiated with ultraviolet light.

((式1)を満たす混合物の製造方法)
上記(式1)を満たす混合物を得るためには、例えば、メソゲン基を有する化合物の精製度合を調節し、最終的に、上記式1を満たす混合物を得る方法が挙げられる。メソゲン基を有する化合物の精製度合は、メソゲン基を有する化合物の合成工程において必要に応じて精製を行うことにより調節することができる。より精製した化合物ほど、黄色度(YI)の値が小さくなる。精製は、合成の各工程において適宜行うことができ、精製方法としてはクロマトグラフィー、再結晶、蒸留、昇華、再沈殿、吸着、分液処理、分散洗浄等が挙げられる。精製剤を用いる場合、精製剤としてシリカゲル、アルミナ、活性炭、活性白土、セライト、ゼオライト、メソポーラスシリカ、カーボンナノチューブ、カーボンナノホーン、備長炭、木炭、グラフェン、イオン交換樹脂、酸性白土、二酸化ケイ素、珪藻土、パーライト、セルロース、有機ポリマー、多孔質ゲル等が挙げられる。
(光学異方体の製造方法)
(光学異方体)
本発明の重合性組成物を用いて作製した光学異方体は、基材、必要に応じて配向膜、及び、重合性組成物の重合体を順次積層したものである。
(塗布)
本発明の光学異方体を得るための塗布法としては、アプリケーター法、バーコーティング法、スピンコーティング法、ロールコーティング法、ダイレクトグラビアコーティング法、リバースグラビアコーティング法、フレキソコーティング法、インクジェット法、ダイコーティング法、キャップコーティング法、ディップコーティング法、スリットコーティング法等、公知慣用の方法を行うことができる。重合性組成物を塗布後、乾燥させる。
(重合工程)
本発明の重合性液晶組成物の重合操作については、重合性液晶組成物中の液晶化合物が基材に対して水平配向、垂直配向、又はハイブリッド配向、あるいはコレステリック配向(平面配向)した状態で一般に紫外線等の光照射、あるいは加熱によって行われる。重合を光照射で行う場合は、具体的には390nm以下の紫外光を照射することが好ましく、250~370nmの波長の光を照射することが最も好ましい。但し、390nm以下の紫外光により重合性組成物が分解などを引き起こす場合は、390nm以上の紫外光で重合処理を行ったほうが好ましい場合もある。この光は、拡散光で、かつ偏光していない光であることが好ましい。
(重合方法)
本発明の重合性液晶組成物を重合させる方法としては、活性エネルギー線を照射する方法や熱重合法等が挙げられるが、加熱を必要とせず、室温で反応が進行することから活性エネルギー線を照射する方法が好ましく、中でも、操作が簡便なことから、紫外線等の光を照射する方法が好ましい。照射時の温度は、本発明の重合性液晶組成物が液晶相を保持できる温度とし、重合性液晶組成物の熱重合の誘起を避けるため、可能な限り30℃以下とすることが好ましい。尚、液晶組成物は、通常、昇温過程において、C(固相)-N(ネマチック)転移温度(以下、C-N転移温度と略す。)から、N-I転移温度範囲内で液晶相を示す。一方、降温過程においては、熱力学的に非平衡状態を取るため、C-N転移温度以下でも凝固せず液晶状態を保つ場合がある。この状態を過冷却状態という。本発明においては、過冷却状態にある液晶組成物も液晶相を保持している状態に含めるものとする。具体的には390nm以下の紫外光を照射することが好ましく、250~370nmの波長の光を照射することが最も好ましい。但し、390nm以下の紫外光により重合性組成物が分解などを引き起こす場合は、390nm以上の紫外光で重合処理を行ったほうが好ましい場合もある。この光は、拡散光で、かつ偏光していない光であることが好ましい。紫外線照射強度は、0.05kW/m2~10kW/m2の範囲が好ましい。特に、0.2kW/m2~2kW/m2の範囲が好ましい。紫外線強度が0.05kW/m2未満の場合、重合を完了させるのに多大な時間がかかる。一方、2kW/m2を超える強度では、重合性液晶組成物中の液晶分子が光分解する傾向にあることや、重合熱が多く発生して重合中の温度が上昇し、重合性液晶のオーダーパラメーターが変化して、重合後のフィルムのリタデーションに狂いが生じる可能性がある。
(用途)
本願発明の重合性液晶組成物を水平配向、垂直配向、又はハイブリッド配向、あるいはコレステリック配向した状態で重合して得られる重合体は、配向性能を有する光学異方体として、光学補償膜、位相差膜、視野角拡大フィルム、輝度向上フィルム、反射フィルム、偏光フィルム、光情報記録材料として用いることができる。また、放熱性を有する接着剤、封止剤、放熱シート、セキュリティー印刷用インキとして用いることができる。
