(Examples 1 to 74 and Comparative Examples 1 to 3) <Preparation of coloring composition> Colored compositions were prepared by mixing the respective raw materials described in Tables 4 to 7.

<Evaluation of Dispersibility: Viscosity> Using an E-type viscometer, the viscosity of the coloring composition at 25° C. was measured on the condition of a rotational speed of 1,000 rpm, and the following criteria were used for evaluation. A: 1 mPa·s or more and 15 mPa·s or less B: More than 15 mPa·s and 30 mPa·s or less C: More than 30mPa·s

<Evaluation of Spectral Characteristics> Each coloring composition was spin-coated on a glass substrate so that the film thickness after baking was 0.6 μm, dried on a hot plate at 100° C. for 120 seconds, and then further heated by a hot plate at 200° C. for 300 seconds. Heat treatment (post-baking) forms a film. Using an ultraviolet-visible-near-infrared spectrophotometer U-4100 (manufactured by Hitachi High-Technologies Corporation) (ref. (refer to); glass substrate), the light in the wavelength range of 300 nm to 1,000 nm was measured on the glass substrate on which the film was formed. Transmittance. The evaluation of the spectral characteristics was performed using the transmittance ratio T calculated by the following formula. The lower the value of the transmittance ratio T, the better the spectrum. T=(Tmin/Tmax)×100(%) Tmax: Maximum transmittance at wavelengths of 500nm to 600nm Tmin: Minimum transmittance at wavelengths of 620nm to 730nm [Evaluation Criteria] A: T<10 B: 10≤T＜20 C: 20≤T＜30 D: 30≤T

<Evaluation test of heat diffusion resistance> In addition to using each green composition obtained above on an 8-inch (203.2 mm) glass wafer with a primer coating, and exposing through a mask with a 5.0 μm square pattern, photolithography In the same way as the performance evaluation test, a 5 μm square pattern (green pixel) was formed. Next, on the glass wafer on which the green pixels were formed, the blue composition 1 and the red composition 1 were used to form the missing portions of the green pixels on the silicon wafer by the same method as in the evaluation test of photolithography. The blue pattern (blue pixel) and the red pattern (red pixel) are displayed. The transmittances (spectrum 1) in the wavelength range of 400 nm to 700 nm were measured using a microscope system (LVmicro V, manufactured by Lambda Vision Inc.) for the red and blue pixels. Then, the glass wafer on which green pixels, blue pixels, and red pixels were formed was heated at 260° C. for 5 minutes using a heating plate in an air environment, and then, using a microscope system (LVmicro V, manufactured by Lambda Vision Inc.), The transmittance in the wavelength range of 400 nm to 700 nm was measured for the blue pixel and the red pixel (spectrum 2). Using the spectrum 1 and spectrum 2 of the blue pixel and the red pixel, the maximum value of the amount of change in transmittance was obtained, and the color mixture was evaluated according to the following criteria. In addition, the measurement of transmittance was performed 5 times for each sample, and the average value of 3 times of the results excluding the maximum value and the minimum value was used. In addition, the maximum value of the amount of change in transmittance refers to the amount of change at the wavelength at which the amount of change in transmittance is the largest in the wavelength range of 400 to 700 nm for the red pixel or blue pixel before and after heating. A: The maximum value of the amount of change in transmittance is less than 3%. B: The maximum value of the amount of change in transmittance is 3% or more and less than 4%. C: The maximum value of the amount of change in transmittance is 4% or more and less than 5%. D: The maximum value of the amount of change in transmittance is 5% or more.

(Example 201: Production of Solid-State Imaging Device) The coloring composition of Example 1 was applied on a silicon wafer by spin coating so that the film thickness after film formation was 0.4 μm. Next, using a hotplate, it heated on the condition of 100 degreeC for 2 minutes. Next, using an i-ray stepper FPA-3000i5+ (manufactured by Canon Inc.), exposure was performed at 1,000 mJ/cm ² through a mask of a dot pattern of 1.0 μm square. Next, spin-on immersion development was performed at 23° C. for 60 seconds using a 0.3 mass % aqueous solution of tetramethylammonium hydroxide (TMAH). Then, it rinsed with a rotary shower, and also rinsed with pure water. Next, using a hot plate, it heated at 200 degreeC for 5 minutes, and formed the pattern by hardening the coloring composition of Example 1 on the silicon wafer. Similarly, the following red (Red) composition and the following blue (Blue) composition were sequentially patterned to form a colored pattern (Bayer pattern) of red, green, and blue. In addition, a Bayer pattern refers to a color filter having one red (Red) element, two green (Green) elements and one blue (Blue) element repeatedly, as disclosed in the specification of US Pat. No. 3,971,065 The resulting pattern is a 2x2 array of chip elements. The obtained color filter is incorporated into a solid-state imaging element according to a known method. It was confirmed that even when any of the coloring compositions produced in the examples were used, the cured film of the solid-state imaging element had excellent adhesion, and a solid-state imaging element having an appropriate image recognition capability was obtained.
