Embodiment 1

[0098] 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 (catalogue value): 4100, degree of dispersion ( catalog value): 1.98] and 144 parts by weight of acetone were charged into a 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 2 wt % 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 washed organic layer was concentrated to 78.3 parts by weight, and after adding 187.9 parts by weight of propylene glycol...

Embodiment 2

[0102] Example 2 A blue filter was prepared in the same manner as in Example 1, except that 20 parts by mass of the colorant (I-1a) was used as the main colorant, and 10 parts by mass of the coloring agent represented by formula (IIIa) Resin A was used as an auxiliary colorant, and 49.25 parts by mass (in terms of solid content) of Resin A was used as an alkali-soluble resin.

Embodiment 3

[0103] Example 3 A blue filter was prepared in the same manner as in Example 1, except that 20 parts by mass of the colorant (II-a) was used as the main colorant, and 10 parts by mass of the colorant (II-a) represented by the formula (I-6a) The colorant of was used as an auxiliary colorant, and 49.25 parts by mass (in terms of solid content) of resin A was used as an alkali-soluble resin.

Abstract

A colored photosensitive resin composition comprising an alkali-soluble resin, a photosensitive compound, a curing agent, a solvent and a colorant represented by the formula (I). The colored photosensitive resin composition can form a color filter array which shows good spectral characteristics.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition which can be used for manufacturing a color filter array to be used in a device for coloring a solid-state image pickup device (such as an image sensor, etc.) and a liquid crystal display Formed on. Background technique [0002] As a color filter array for coloring a solid-state image pickup device and a liquid crystal display, for example, there is known a color filter array in which a red filter layer (R), a green filter layer (G) and the blue filter layer (B) are formed adjacent to each other on the same surface of the device. For the filter layer, in addition to the primary color combinations of red (R), green (G) and blue (B), complementary colors of yellow (Y), magenta (M) and cyan (C) can be used. combination. [0003] A color filter array is generally produced by a color resist method in which colored photosensitive resin compositions corresponding to respective filt...
