Problems solved by technology

[0004] However, good spectral characteristics and good light resistance are required for color filter arrays, and the color filter arrays described in JP-A-6-75375 and JP-B-7-111485 cannot achieve both. a characteristic
For example, in the colored photosensitive resin composition described in JP-B-7-111485, the transmittance at a wavelength of 650 nm is about 85%, and the transmittance at a wavelength of 535 nm is about 0.6%, but when the When the transmittance at a wavelength of 650nm is controlled to 90% or more, the transmittance at a wavelength of 535nm tends to exceed 1%, so spectral characteristics become insufficient

Embodiment 1

[0094] Synthesis Example 1 36.0 parts by weight of poly(p-hydroxystyrene) [trade name: "MARUKA LYNCURM" (manufacturer: Maruzen Petrochemical Co., Ltd.), weight average molecular weight (catalog value): 4100, dispersion degree ( Catalog value): 1.98] and 144 parts by weight of acetone were charged into the reaction vessel, and then dissolved while stirring. 20.7 parts by weight of anhydrous potassium carbonate and 9.35 parts by weight of ethyl iodide were added to the solution, and then reflux was started by heating. After continuing to reflux for 15 hours, 72 parts by weight of methyl isobutyl ketone was added, and the organic layer was washed with 92.8 parts by weight of a 2% by weight oxalic acid aqueous solution. Then, 96 parts by weight of ethyl isobutyl ketone was added, and the organic layer was washed with 64.7 parts by weight of ion-exchanged water. The organic layer after washing was concentrated to 78.3 parts by weight, and after adding 187.9 parts by weight of propylene...

Embodiment 2

[0099] Example 2 produced a red photosensitive resin composition and an optical filter in the same manner as Example 1, except that the combination of colorants was changed to 19 parts by weight of the compound represented by formula (Ia) (as (alkyl)amino group). Xanthene colorant), 19 parts by weight of CI Solvent Orange 56 (as a pyrazolone azo colorant), and 18 parts by weight of CI Solvent Yellow 162 (as a pyridone azo dye).

Abstract

A colored photosensitive resin composition comprises a compound represented by the formula (I) or a salt thereof: wherein R<10>, R<11>, R<13 >and R<14 >represent independently of each other a hydrogen atom or an alkyl group; R<12 >represents a sulfonic acid group, a carboxylic acid group, an ester thereof, or an amide represented by the formula (1) -SO2NHR<15 >, and (1) X<-> represents BF4<->, PF6<->, Y<-> or YO4<-> (in which Y represents a halogen atom), or a dye having a sulfonic acid group.

Description

Technical field [0001] The present invention relates to a colored photosensitive resin composition, which can be used to manufacture a color filter array, which will be used in a solid-state image pickup device (such as an image sensor, etc.) and a device for developing colors in a liquid crystal display. Formed on. Background technique [0002] For the color filter arrays that make solid-state image pickup devices and liquid crystal displays develop colors, for example, a color filter array is known in which a red filter layer (R) and a green filter layer (G) And the blue filter layer (B) are formed adjacent to each other on the same surface of the device. The plane pattern of each filter layer (R, G, B) of the color filter array is appropriately set. For the filter layer, in addition to the combination of the primary colors of red (R), green (G) and blue (B), complementary colors of yellow (Y), magenta (M) and cyan (C) can be used combination. [0003] The color filter array is...
