Description
本発明は染料として有用な新規なメチン化合物に関する。 The present invention relates to a novel methine compound useful as a dye.
色素は一般に染料と顔料とに大きく分類される。顔料は耐光性、耐溶剤性といった堅牢性が高いものの、溶媒に不溶なため、取り扱いが難しい。例えば、カラーフィルター等、光学用途への応用を想定した場合、高い透明性の確保が必要不可欠であり、溶剤に不溶な顔料を微細化する技術や溶媒に分散させるための高度な分散技術が必要となる。一方、染料は一般に溶媒に可溶であるため取り扱い易く、高い着色力、透明性を示すことが知られているが、染料であっても必ずしも全ての溶媒に対して良好な溶解性を有する訳ではなく、ある特定の溶媒に対しては難溶性を示すものがほとんどである。 In general, dyes are roughly classified into dyes and pigments. Although pigments have high fastness such as light resistance and solvent resistance, they are difficult to handle because they are insoluble in solvents. For example, assuming application to optical applications such as color filters, ensuring high transparency is indispensable, and technology for minimizing pigments that are insoluble in solvents and advanced dispersion technology for dispersing in solvents are necessary. It becomes. On the other hand, dyes are generally soluble in solvents and are therefore easy to handle and are known to exhibit high coloring power and transparency. However, even dyes do not necessarily have good solubility in all solvents. However, most of them are hardly soluble in a specific solvent.
溶媒に対する溶解性の乏しい染料を用いて物体を着色する方法としては、例えば、前記した顔料のように高度な分散技術を用いた湿式着色法を用いる他、真空蒸着などの気相から物体上へ染料分子を析出させる乾式着色法などがある。湿式着色法は、溶媒に対する溶解性の乏しい染料を溶媒中に微細に分散するために長時間の分散工程を必要とする上、分散助剤として種々の添加剤を加える必要があり、必ずしも適用範囲が広いとは言えない。また、乾式着色法は、真空装置のような大型の設備が必要であり、更に染料を気化させる高温条件に耐える耐久性の良い色素は数が限られているため、必ずしも適用範囲が広いとは言えない。 As a method of coloring an object using a dye having poor solubility in a solvent, for example, a wet coloring method using an advanced dispersion technique such as the above-described pigment is used, or from a gas phase such as vacuum deposition onto the object. There is a dry coloring method in which dye molecules are deposited. The wet coloring method requires a long dispersion step in order to finely disperse a dye having poor solubility in a solvent in the solvent, and it is necessary to add various additives as a dispersion aid. Is not wide. In addition, the dry coloring method requires large equipment such as a vacuum device, and the number of durable dyes that can withstand high temperature conditions that vaporize the dye is limited, so that the range of application is not necessarily wide. I can not say.
また、溶媒に対する溶解性の乏しい染料骨格に、嵩高い置換基を導入し、溶媒に対する溶解性を得ることも可能であるが、導入した置換基効果の影響を受けるため、必ずしも物性が元の化合物と等しくなるとは限らない。 It is also possible to introduce a bulky substituent into a dye skeleton having poor solubility in a solvent to obtain solubility in the solvent. However, since it is affected by the introduced substituent effect, the physical properties are not necessarily the original compounds. Are not necessarily equal.
メチン化合物は、色相が鮮明で、高発色性を有しており、光や熱等に対して堅牢であることから、染料として広く使用されており、各種塗料、水性インキ、油性インキ、インクジェット用インキ、カラーフィルター用など幅広い用途での応用がなされている。このような染料として例えば、非特許文献１に記載されているような下記式（１００）で表されるメチン化合物が知られている。
しかしながら、本発明者らが検討した結果、下記式（１００）で表されるメチン化合物はカラーフィルター用着色樹脂組成物に用いられるシクロペンタノンや乳酸エチルなどの溶剤への溶解性が不充分であった。
Methine compounds are widely used as dyes because of their clear hues, high color development, and robustness to light, heat, etc. For various paints, water-based inks, oil-based inks, and inkjets. It is used in a wide range of applications such as inks and color filters. As such a dye, for example, a methine compound represented by the following formula (100) as described in Non-Patent Document 1 is known.
However, as a result of investigations by the present inventors, the methine compound represented by the following formula (100) has insufficient solubility in a solvent such as cyclopentanone or ethyl lactate used in the colored resin composition for color filters. there were.
本発明は、溶剤溶解性に優れたメチン化合物、該メチン化合物を含有する染料組成物及び該染料組成物を用いて得られるカラーフィルターの提供を目的とする。 An object of this invention is to provide the methine compound excellent in solvent solubility, the dye composition containing this methine compound, and the color filter obtained using this dye composition.
