Description
本発明は、直鎖上に並んだ環構造を有し、その両端に異なるスペーサーを介して（メタ）アクリル基を有する重合性化合物に関し、詳細には、（メタ）アクリル基を重合して硬化膜とした際に、優れた耐溶剤性と光学特性を示す光学異方体となる重合性化合物に関する。 The present invention relates to a polymerizable compound having a ring structure arranged in a straight chain and having (meth) acrylic groups via different spacers at both ends thereof. Specifically, the (meth) acrylic group is polymerized and cured. The present invention relates to a polymerizable compound which becomes an optical anisotropic body exhibiting excellent solvent resistance and optical properties when formed into a film.
近年、液晶物質は、ＴＮ型やＳＴＮ型に代表されるディスプレイ素子等の液晶分子の可逆的運動を利用した表示媒体への応用以外にも、その配向性と屈折率、誘電率、磁化率等の物理的性質の異方性を利用して、位相差板、偏光板、光偏光プリズム、各種光フィルター等の光学異方体への応用が検討されている。 In recent years, in addition to application to display media using reversible motion of liquid crystal molecules such as display elements typified by TN type and STN type, the liquid crystal substance has its orientation, refractive index, dielectric constant, magnetic susceptibility, etc. Utilizing the anisotropy of these physical properties, application to optical anisotropic bodies such as retardation plates, polarizing plates, light polarizing prisms, and various optical filters has been studied.
このように液晶物質を構成材料とする光学異方体は、安定で均一な光学特性を得るために、液晶状態における液晶分子の均一な配向状態を半永久的に固定化して、機械的にも熱的にも安定なガラス転移温度（以下「Ｔｇ」という）の高い、配向性に優れた重合物とすることが必須である。 Thus, in order to obtain stable and uniform optical characteristics, an optical anisotropic body composed of a liquid crystal substance has a uniform alignment state of liquid crystal molecules in a liquid crystal state semi-permanently and is mechanically heated. In particular, it is essential that the polymer has a high glass transition temperature (hereinafter referred to as “Tg”) and excellent orientation.
液晶状態における液晶分子の均一な配向状態を半永久的に固定化する手段としては、例えば、重合性官能基を有する液晶性化合物又はこのような化合物を含有する重合性液晶組成物を液晶状態で均一に配向させた後、液晶状態を保持したまま紫外線等のエネルギー線を照射することによって光重合させて、均一な配向状態を半永久的に固定化する方法が既に知られている。 As a means for semi-permanently fixing the uniform alignment state of the liquid crystal molecules in the liquid crystal state, for example, a liquid crystal compound having a polymerizable functional group or a polymerizable liquid crystal composition containing such a compound is uniform in the liquid crystal state. There is already known a method of semi-permanently fixing a uniform alignment state by photopolymerization by irradiating energy rays such as ultraviolet rays after maintaining the liquid crystal state.
重合性官能基を有する液晶性化合物としては、（メタ）アクリル基を有する重合性化合物が知られている（例えば、特許文献１、特許文献２、特許文献３及び特許文献４を参照）。これらの文献に記載された重合性化合物は、液晶相を示す温度が高く、高温での重合、硬化が必要であった。 As liquid crystalline compounds having a polymerizable functional group, polymerizable compounds having a (meth) acryl group are known (see, for example, Patent Document 1, Patent Document 2, Patent Document 3 and Patent Document 4). The polymerizable compounds described in these documents have a high temperature showing a liquid crystal phase, and polymerization and curing at a high temperature are necessary.
高温での重合は、光重合と熱重合とが並行して起きるため、硬化物の物性が不均一になりやすく、配向状態の固定が困難である。また、硬化時の温度管理を容易にするために、液晶組成物がより低温で液晶相を示す液晶性化合物が求められていた。 Since polymerization at high temperature occurs in parallel with photopolymerization and thermal polymerization, the physical properties of the cured product are likely to be non-uniform, and it is difficult to fix the alignment state. Further, in order to facilitate temperature control during curing, a liquid crystalline compound in which the liquid crystal composition exhibits a liquid crystal phase at a lower temperature has been demanded.
本発明の目的は、配向性に優れ、低温で液晶相を示す新規な重合性化合物、及び該化合物を含有する重合性液晶組成物を提供することにある。 An object of the present invention is to provide a novel polymerizable compound that is excellent in orientation and exhibits a liquid crystal phase at a low temperature, and a polymerizable liquid crystal composition containing the compound.

また、本発明は、上記重合性化合物を重合してなる単独重合物を提供するものである。 The present invention also provides a homopolymer obtained by polymerizing the polymerizable compound.
また、本発明は、上記重合性化合物と他のエチレン性不飽和結合を有する化合物とを共重合してなる共重合物を提供するものである。 Moreover, this invention provides the copolymer formed by copolymerizing the said polymeric compound and the compound which has another ethylenically unsaturated bond.
