Among them, the photolithography method is preferred. The photolithography method is a method of applying the yellow colored curable composition on a substrate, drying it to form a colored composition layer, and exposing and developing the colored composition layer through a photomask. In the photolithography method, a colored coating film that is a hardened product of the colored composition layer can be formed by not using a photomask during exposure and/or not performing development. The colored pattern or colored coating film formed in the manner described above is the color filter of the present invention.

Resin plates such as ethylene terephthalate; silicon; aluminum, silver, silver/copper/palladium alloy thin films, etc. formed on the substrate. Other color filter layers, resin layers, transistors, circuits, etc. can also be formed on these substrates.

The use of photolithography to form each color pixel can be performed under known or customary devices or conditions. For example, it can be produced as follows. First, the colored curable composition is coated on the substrate, and volatile components such as the solvent are removed by heat drying (pre-baking) and/or reduced pressure drying to dry, thereby obtaining a smooth colored composition layer. As the coating method, a spin coating method, a slit coating method, a slit and spin coating method, etc. can be cited.

In the case of drying under reduced pressure, it is preferably performed under a pressure of 50 Pa to 150 Pa in a temperature range of 20°C to 25°C.

Then, the colored composition layer is exposed via a photomask for forming a target colored pattern. The pattern on the mask is not particularly limited, and a pattern corresponding to the intended use can be used. As the light source used for exposure, a light source that generates light with a wavelength of 250 nm to 450 nm is preferred. For example, for light less than 350 nm, use a filter that cuts off the wavelength range, or for light near 436 nm, near 408 nm, and near 365 nm, use band-pass filters that extract these wavelength ranges Perform selective extraction. Specifically, as the light source, a mercury lamp, a light emitting diode, a metal halide lamp, a halogen lamp, etc. can be cited. In order to uniformly irradiate the entire exposure surface with parallel light or to accurately align the mask and the substrate on which the colored composition layer is formed, it is preferable to use an exposure device such as a mask aligner and a stepper.

By contacting the exposed coloring composition layer with a developing solution for development, a coloring pattern is formed on the substrate. By developing, the unexposed part of the colored composition layer is dissolved in the developing solution and removed. As the developer, for example, an aqueous solution of an alkaline compound such as potassium hydroxide, sodium hydrogen carbonate, sodium carbonate, and tetramethylammonium hydroxide is preferred. The concentration of these basic compounds in the aqueous solution is preferably 0.01% by mass to 10% by mass, more preferably 0.03% by mass to 5% by mass. Furthermore, the developer may contain a surfactant. The development method may be any of a liquid coating method, a dipping method, and a spray method. Furthermore, the substrate may be inclined to an arbitrary angle during development. After development, it is preferable to wash with water.

Furthermore, it is preferable to post-bak the obtained colored pattern. The post-baking temperature is preferably 150°C to 250°C, more preferably 160°C to 235°C. The post-baking time is preferably 1 minute to 120 minutes, more preferably 3 minutes to 60 minutes.

Since the film thickness of the obtained color filter affects adjacent pixels, it is preferably as thin as possible. If the film thickness is thick, color mixing with the light of adjacent pixels may occur. The film thickness of the post-baked color filter is, for example, preferably 3 μm or less, more preferably 2.8 μm or less, still more preferably 2.5 μm or less, and even more preferably 2.0 μm or less. The lower limit of the film thickness of the color filter is not particularly limited, but it is usually 0.3 μm or more, and may be 0.5 μm or more.

Regarding the yellow colored curable composition of the present invention, when the yellow colored curable composition is used to form a colored pattern or colored coating film with a film thickness of 0.6 μm, the transmittance is preferably 7% or less at a wavelength of 430 nm, And it is over 85% at a wavelength of 500 nm. In addition, it is preferable that the transmittance curve from the short-wavelength side to the long-wavelength side is not smooth and not too steep. Specifically, the difference between the transmittance at 460 nm and the transmittance at 485 nm (transmittance ( 485 nm)-Transmittance (460 nm)) is 55 or more and 75 or less. If the transmittance and the transmittance curve are within the above range, the color characteristic as yellow can be made good. Furthermore, the transmittance at a wavelength of 430 nm is more preferably 6% or less, and still more preferably 5% or less. As the transmittance at a wavelength of 500 nm, it is more preferably 86% or more, and still more preferably 87% or more. The difference between the transmittance at 460 nm and the transmittance at 485 nm is more preferably 60 or more.

By using the yellow colored curable composition of the present invention, it is possible to manufacture a color filter having good yellow color characteristics especially as a solid-state imaging device. The color filter can be used for solid-state imaging devices, but can also be effectively used as a color filter used in other display devices (for example, liquid crystal display devices, organic electroluminescence (EL) devices, electronic paper, etc.).

[Preparation of Colored Pattern] A yellow colored curable composition was applied on a 4-inch silicone substrate by spin coating, and then pre-baked at 80°C for 2 minutes to obtain a colored composition layer. After cooling, an exposure machine (NSR-1755i7A; manufactured by Nikon (stock)) was used to irradiate the coloring composition layer formed on the substrate with light at an exposure amount of 300 mJ/cm ² . The colored composition layer irradiated with light is immersed and developed in an aqueous developer containing tetramethylammonium hydroxide at 23°C for 50 seconds, washed with water, and post-baked in an oven at 230°C for 10 minutes. Thus, a colored pattern is obtained.

[Film thickness measurement] For the obtained colored pattern, the film thickness (μm) was measured using a film thickness measuring device (DEKTAK3; manufactured by Nippon Vacuum Technology Co., Ltd.). The results are shown in Table 2.

[Transmittance Evaluation] The obtained colored pattern was subjected to spectrophotometric measurement using a spectrophotometer (LvmicroV; manufactured by LambdaVision (Stock)) to evaluate the transmittance. The results are shown in Table 2. If the transmittance at a wavelength of 430 nm is 7% or less, the yellow color characteristic (430 nm) is good (○), and if the transmittance at a wavelength of 500 nm is 85% or more, the yellow color characteristic (500 nm) ) Good (○). The case outside the above-mentioned range is regarded as yellow color characteristic poor (×). In addition, the transmittance curve from the short-wavelength side to the long-wavelength side was evaluated in the following manner. If the difference between the transmittance at 460 nm and the transmittance at 485 nm (transmittance (485 nm)-transmittance (460 nm)) is greater than 75, the transmittance curve is too steep, if it is less than 55, the transmittance curve is flat Therefore, it is assumed that the yellow color characteristic is poor (×). If the difference between the transmittance at 460 nm and the transmittance at 485 nm (transmittance (485 nm)-transmittance (460 nm)) is 55 or more and 75 or less, then Since good yellow color characteristics can be obtained, the yellow color characteristics are good (○).
