- a color filter used in a liquid crystal display arranges a plurality of colors regularly on a transparent glass substrate, and transmits only light in a necessary wavelength region from white light of a backlight that passes through the color filter. It is a member that realizes color display.
- the colors used there generally include the three primary colors of red, green, and blue, and improvements have been made to color materials, resins, additives, and the like used to adjust the transmission spectrum. Among them, green colorants for color filters are required to have high brightness and an expanded color reproduction range from the viewpoint of improving display image quality.

- the pigment green 7 has a lower transmittance than the pigment green 36 and the pigment green 58, there is a problem that the luminance of the obtained display is lowered.
- the luminance can be compensated for by increasing the amount of light from the backlight, but an improvement is required because a new problem of increased power consumption occurs. From the above, a color material for color filters that achieves both luminance and color reproducibility is desired.

- halogenated zinc phthalocyanine pigment used in the present invention at least one halogen atom selected from chlorine, bromine, fluorine and iodine is present in the phthalocyanine ring which has zinc metal at the center and may be substituted with a substituent other than halogen. These are substituted compounds, and the total number of each substituent is 16 at the maximum.
- the portion not substituted with halogen and a substituent other than halogen refers to a hydrogen atom.
- the zinc halide phthalocyanine pigment used in the present invention has an average of 10 to 14 halogen atoms in one molecule from the viewpoint of designing a color filter having a wide color reproduction range, and among these, the average number of bromine atoms is 8 The number is preferably 12 and the average number of chlorine atoms is 2-5.
- the pigment derivative used in the present invention can be represented by the general formula (1).
- Z 1 to Z 16 are bromine atom, chlorine atom, hydrogen atom or sulfo group. And at least any one selected from Z 1 , Z 4 , Z 5 , Z 8 , Z 9 , Z 12 , Z 13 , and Z 16 on the average in one molecule contains a chlorine atom. It is preferable to use what has.

- the pigment composition of the present invention as described above was not based on a simple combination of a conventional pigment and a pigment derivative of the same skeleton, but the present invention was completed based on the following idea.
- a general organic pigment has a highly conjugated system formed as a whole molecule, and it is energetically stable to have a planar structure. When these planar molecules are arranged so as to be stacked (in parallel), conjugated ⁇ electrons between the molecules overlap each other, so that a more stable state is obtained. Since the pigment derivative represented by the general formula (1) used in the present invention has a phthalocyanine ring, it has a planar structure, and interaction with the planar structure of the organic pigment tends to work. Further, when the main pigment is a halogenated phthalocyanine pigment, it is considered that the halogen- ⁇ interaction is particularly easy to work with the ⁇ electrons of the derivative.
- the derivative is efficiently adsorbed on the active surface of the halogenated phthalocyanine pigment newly generated during dispersion.

Therefore, it is preferable that the transmittance in this wavelength range is low. It is described in Kaihei 8-240708. When the chromaticity y value is low, it is necessary to increase the chromaticity y value by increasing the film thickness, but when the film thickness is increased, the luminance decreases.

Y138 is described in JP-A-2015-26077 when it shifts from the absorption band to the transmission band around 460 nm, so that it can produce absorption at a shorter wavelength than 460 nm, but it is not suitable for making absorption at the longer wavelength side.

Abstract
Description
また、ハロゲン化銅フタロシアニン顔料と、低ハロゲン化銅フタロシアニンスルホン酸誘導体とを含有し、一次粒子の平均粒子径0.01~0.1μm且つアスペクト比1~3である緑色顔料組成物を用いて、コントラストが良好なカラーフィルタを作製することが提案されている(特許文献2)。しかし、主顔料とする銅フタロシアニン顔料の輝度の低さに起因して、近年要求される性能を満足できない場合があった。
このように、高輝度化、色再現範囲の拡大を目的としたカラーフィルタを形成するためには、これら先行技術では、近年急速に高まる要求性能を満足するには不十分であり、未だ目的は達成できていないのが実情である。
なかでも、本発明に用いるハロゲン化亜鉛フタロシアニン顔料は、色再現範囲の広いカラーフィルタを設計する観点から、1分子中にハロゲン原子を平均10~14個有し、このうち臭素原子数が平均8~12個であり、塩素原子数が平均2~5個であるものが好ましい。
なかでも、緑色カラーフィルタの主顔料と顔料誘導体の色相を類似させる観点から、前記顔料誘導体は、前記一般式(1)中、Z1~Z16が臭素原子、塩素原子、水素原子又はスルホ基の何れかを有し、かつ一分子中の平均で、少なくともZ1、Z4、Z5、Z8、Z9、Z12、Z13、Z16から選ばれるいずれか2以上が塩素原子を有するものを用いることが好ましい。
なお、Z1、Z4、Z5、Z8、Z9、Z12、Z13、Z16の位置に塩素原子又は臭素原子が入ると色相が緑味化することは、特開2010-189528に記載されている。
(B)さらに、顔料と誘導体の吸収スペクトルの重なり方にも着目して本発明を完成するに至った。緑色画素のカラーフィルタにおいて明るく鮮明な表示を得るためには、510nmから560nmまでの透過率を高くすることが特に好ましい。この狭い波長域のみを透過するカラーフィルタを設計するために、緑色顔料と黄色顔料とを組み合わせて使用するため、緑色顔料に処理される顔料誘導体は、510~560nmにおいて緑色顔料の透過波長と類似する組合せとすることが好ましい。
(C)また、430nmから460nmの透過率が高いと、色度y値が大幅に低下し、緑の鮮明さが大きく損なわれてしまうため、この波長範囲の透過率は低いほうが好ましいことが特開平8-240708に記載されている。色度y値が低い場合には膜厚を厚くして色度y値を高くする必要があるが、膜厚を厚くすると輝度が低下してしまう。したがって、430nmから460nmの透過率がなるべく低くなるような顔料誘導体の選択が必要である。特に、カラーフィルタの緑色画素は、緑色顔料に対してキノフタロン系黄色顔料であるC.I.ピグメントイエロー138(Y138)を組み合わせて用いることが一般的である。Y138は、460nmあたりで吸収帯から透過帯へ移行すると特開2015-26077に記載があることから、460nmよりも短波長の吸収を作り出すことはできるが長波長側の吸収を作るには不向きであるため、緑顔料に処理される誘導体の460nmの透過率は低いほうが好ましい。
ここで、ハロゲン化亜鉛フタロシアニン顔料を用いて極大透過波長における分光透過率が70%になるように形成した塗膜の510nm~560nmの透過率の積分値をD1とし、前記一般式(1)で表される顔料誘導体を酸化アルミニウムに担持させて得られる誘導体担持体を用いて極大透過波長における分光透過率が70%になるように形成した塗膜の510nm~560nmの透過率の積分値をD2とした際に、D1とD2の比率(D2/D1)が0.7以上となる分光特性を有するカラーフィルタ用顔料組成物であることが、顔料誘導体による緑色カラーフィルタの輝度低下を最小限にとどめることができるため好ましい。また、より輝度の高い緑色カラーフィルタを設計するために、D1とD2の比率(D2/D1)が1.0以上となる分光特性を有するカラーフィルタ用顔料組成物であることがより好ましく、D1とD2の比率(D2/D1)が1.2以上となる分光特性を有するカラーフィルタ用顔料組成物であることがさらに好ましい。
そして、前記一般式(1)で表される顔料誘導体を酸化アルミニウムに担持させて得られる誘導体担持体を用いて極大透過波長における分光透過率が70%になるように形成した塗膜の460nmにおける透過率が60%以下となる分光特性を有するカラーフィルタ用顔料組成物であることが、色度yの低下が抑制された色再現性の高い緑色カラーフィルタを作製できるため好ましい。また、より色再現性の高い緑色カラーフィルタを設計するために、460nmにおける透過率が55%以下となる分光特性を有するカラーフィルタ用顔料組成物であることがより好ましく、460nmにおける透過率が50%以下となる分光特性を有するカラーフィルタ用顔料組成物であることがさらに好ましい。
本発明の顔料組成物を用いて緑色画素を形成することで、カラーフィルタを得ることができる。
本発明の顔料組成物は、公知の方法でカラーフィルタの緑色画素部のパターンの形成に用いることができる。典型的には、本顔料組成物と、感光性樹脂とを必須成分して含むカラーフィルタ緑色画素部用感光性組成物を得ることができる。
