 本発明は、有機顔料を含む着色組成物に関する。また、本発明は、着色組成物を用いた膜、カラーフィルタ、固体撮像素子および画像表示装置に関する。 The present invention relates to a coloring composition containing an organic pigment. The present invention also relates to a film, a color filter, a solid-state image pickup device, and an image display device using a coloring composition.
 近年、デジタルカメラ、カメラ付き携帯電話等の普及から、電荷結合素子(CCD)イメージセンサなどの固体撮像素子の需要が大きく伸びている。ディスプレイや光学素子のキーデバイスとしてカラーフィルタが使用されている。カラーフィルタは、通常、赤、緑及び青の3原色の画素を備えており、透過光を3原色へ分解する役割を果たしている。 In recent years, with the widespread use of digital cameras, camera-equipped mobile phones, etc., demand for solid-state image sensors such as charge-coupled device (CCD) image sensors has increased significantly. Color filters are used as key devices for displays and optical elements. A color filter usually includes pixels of the three primary colors of red, green, and blue, and plays a role of decomposing transmitted light into the three primary colors.
 カラーフィルタの各色の着色画素は、顔料などの色材を含む着色組成物を用いて製造されている。 The colored pixels of each color of the color filter are manufactured by using a coloring composition containing a coloring material such as a pigment.
 また、特許文献1には、潜在性酸化防止剤(A)及び着色剤(B)を含有する着色組成物に関する発明が記載されている。 Further, Patent Document 1 describes an invention relating to a coloring composition containing a latent antioxidant (A) and a coloring agent (B).

 本発明者が、有機顔料を含む着色組成物を用いて得られる膜について鋭意検討を進めたところ、長期間の加熱処理(例えば、130℃で1000時間の加熱処理)後の膜の分光変動や色ムラについて、更なる改善の余地があることが分かった。特に、膜中の色材の含有量が多くなるほど、長期の耐熱試験後の膜の分光変動や色ムラが大きくなる傾向にあった。 As a result of diligent studies on a film obtained by using a coloring composition containing an organic pigment, the present inventor found that the spectral fluctuation of the film after a long-term heat treatment (for example, heat treatment at 130 ° C. for 1000 hours) was observed. It was found that there is room for further improvement in color unevenness. In particular, as the content of the coloring material in the film increases, the spectral fluctuation and color unevenness of the film after a long-term heat resistance test tend to increase.

A first aspect of the coloring composition of the present invention comprises a coloring material containing an organic pigment, a resin, and a compound A in which a phenolic hydroxy group of a phenolic antioxidant is protected by a protective group that can be desorbed by heating. It is a coloring composition containing 40% by mass or more of a coloring material in the total solid content of the coloring composition.

The detailed reason why such an effect is obtained is unknown, but it is presumed to be due to the following.
 本発明の着色組成物に含まれる上述した特定化合物は、製膜時(例えばポストベーク時など)に保護基が脱離してフェノール性ヒドロキシ基が生成され、酸化防止剤としての機能が発揮されると推測される。そして、特定化合物から生成される酸化防止剤として機能する成分の作用により、高温下での有機顔料の劣化や凝集を抑制することができたと推測される。このため、本発明の着色組成物は、長期間の加熱処理後も分光変動が小さく、色ムラの発生が抑制された膜を形成することができると推測される。 The above-mentioned specific compound contained in the coloring composition of the present invention has a protective group desorbed at the time of film formation (for example, at the time of post-baking) to generate a phenolic hydroxy group, and exhibits a function as an antioxidant. It is presumed. It is presumed that the action of the component that functions as an antioxidant produced from the specific compound could suppress the deterioration and aggregation of the organic pigment at high temperatures. Therefore, it is presumed that the coloring composition of the present invention can form a film in which spectral fluctuation is small and the occurrence of color unevenness is suppressed even after a long-term heat treatment.
 また、酸化防止剤を含む着色組成物を用いて膜を形成する場合、製膜時の加熱や露光などによって酸化防止剤が分解や変性して、膜中に十分な量の酸化防止剤が残存していないことがある。これに対し、上述した特定化合物は、製膜時に保護基が脱離してフェノール性ヒドロキシ基が生成されて、酸化防止剤としての機能が発揮されるものであるため、特定化合物の含有量が少量であっても膜中に十分な量の酸化防止剤として機能する成分を含有させることができる。このため、本発明の着色組成物は処方設計の自由度をより高めることもできる。 Further, when a film is formed using a coloring composition containing an antioxidant, the antioxidant is decomposed or denatured by heating or exposure during film formation, and a sufficient amount of the antioxidant remains in the film. I may not have done it. On the other hand, the above-mentioned specific compound has a small content of the specific compound because the protecting group is desorbed at the time of film formation to generate a phenolic hydroxy group and the specific compound exhibits a function as an antioxidant. Even so, the membrane can contain a sufficient amount of a component that functions as an antioxidant. Therefore, the coloring composition of the present invention can further increase the degree of freedom in formulation design.

According to this aspect, it is possible to more effectively suppress the spectral fluctuation of the film and the occurrence of color unevenness after a long-term heat treatment. The detailed reason why such an effect is obtained is unknown, but it is presumed to be due to the following. That is, the action of the acid group of the acidic graft resin during film formation promotes the elimination reaction of the protecting group from the above-mentioned specific compound, and the film contains a component that functions as an antioxidant produced from the specific compound. It is presumed that the amount can be increased. Then, the aggregation of the organic pigment can be suppressed by the graft chain of the acidic graft resin, and further, the deterioration and aggregation of the organic pigment at high temperature are suppressed by the action of the component which functions as an antioxidant produced from the specific compound. It is speculated that it can be done. For this reason, it is presumed that the spectral fluctuation of the film after a long-term heat treatment and the occurrence of color unevenness can be further suppressed.

It may be exposed in an oxygen-free environment (for example, 22% by volume, 30% by volume, or 50% by volume) in a high oxygen atmosphere having an oxygen concentration of more than 21% by volume. The exposure illuminance can be set as appropriate, and is usually selected from the range of 1000 W / m 2 to 100,000 W / m 2 (for example, 5000 W / m 2 , 15,000 W / m 2 , or 35,000 W / m 2).

Further, the developer may further contain a surfactant. From the viewpoint of convenience of transfer and storage, the developer may be once produced as a concentrated solution and diluted to a concentration required for use. The dilution ratio is not particularly limited, but can be set in the range of, for example, 1.5 to 100 times. It is also preferable to wash (rinse) with pure water after development. Further, it is preferable that the rinsing is performed by supplying the rinsing liquid to the developed colored composition layer while rotating the support on which the developed colored composition layer is formed. It is also preferable to move the nozzle for discharging the rinse liquid from the central portion of the support to the peripheral edge of the support.

The underlayer was formed by heating for 1 hour. Each coloring composition was applied onto the glass wafer with a base layer by a spin coating method so that the film thickness after post-baking would be the film thickness shown in the table. Then, using a hot plate, the composition layer was formed by heating at 100 ° C. for 2 minutes. Next, the composition layer was exposed to light having a wavelength of 365 nm at an exposure amount of 1000 mJ / cm 2 using an i-line stepper exposure device (FPA-3000i5 +, manufactured by Canon Inc.). Next, the glass wafer on which the composition layer after exposure was formed was placed on a horizontal rotary table of a spin shower developer (DW-30 type, manufactured by Chemitronics Co., Ltd.), and CD-2000 (FUJIFILM) was placed. Paddle development was performed at 23 ° C. for 60 seconds using a 60% diluted solution manufactured by Electronics Materials Co., Ltd. Next, the glass wafer is fixed to a horizontal rotary table by a vacuum chuck method, and while the glass wafer is rotated at a rotation speed of 50 rpm by a rotating device, pure water is supplied from above the center of rotation in a shower shape from a ejection nozzle to perform a rinse treatment. And then spray dried. Further, heat treatment (post-baking) was performed for 480 seconds using a hot plate at 200 ° C. to obtain a first-layer colored film. A coloring composition for color mixing evaluation was applied onto the obtained first colored film using a spin coater so that the film thickness after prebaking was 0.6 μm, and 120 using a hot plate at 100 ° C. Heat treatment (pre-baking) was performed for seconds to obtain a laminated color filter in which a coloring composition layer (second layer) for color mixing evaluation was formed on the first coloring film. Next, the obtained laminated color filter was developed, rinsed and spray-dried in the same manner as in the formation of the first colored pixel, and the colored composition layer for color mixing evaluation was developed and removed.
The spectral variation (ΔT% max) of the maximum transmittance of the first colored film immediately after the preparation of the first colored film and after the development and removal of the colored composition layer for color mixing evaluation was measured by MCPD-3000 (Otsuka Electronics (Otsuka Electronics Co., Ltd.). The color mixture of the residue of the second layer coloring composition remaining on the first layer coloring film was evaluated. The maximum transmittance is the amount of change in the transmittance of the first colored film immediately after the production of the first colored film and after the development and removal of the colored composition layer for color mixing evaluation, and is the change in the transmittance. It is the amount of change in transmittance at the wavelength with the largest amount.
