Embodiment

[0308] The following examples are given to further specifically illustrate the present invention. Unless otherwise specified, "%" and "part" in an example are mass % and a mass part.

Synthetic example 1

[0310] After adding 250 parts of water and 50 parts of N-methylpyrrolidone to 25.0 parts of o-toluidine-4-sulfonic acid tetrahydrate represented by formula (a-1), adjust the pH with 30% aqueous sodium hydroxide solution under ice cooling to 7-8. The following operations were performed under ice cooling. 18.4 parts of sodium nitrite was added and stirred for 30 minutes. 64.8 parts of 35% hydrochloric acid were gradually added in small amounts to obtain a brown solution, which was then stirred for 2 hours. An aqueous solution obtained by dissolving 16.7 parts of sulfamic acid in 170 parts of water was added to the reaction solution and stirred to obtain a suspension containing a diazonium salt.

[0311]

[0312] After adding 173 parts of water and 19 parts of N-methylpyrrolidone to 19.3 parts of 1-butyl-3-cyano-4-methyl-6-hydroxypyridin-2-one represented by formula (c-1), The pH was adjusted to 8-9 with 30% aqueous sodium hydroxide solution under ice cooling.

[0313] ...

Synthetic example 2

[0326] After adding 200 parts of water and 50 parts of N-methylpyrrolidone to 25.0 parts of m-toluidine-4-sulfonic acid represented by formula (a-2), adjust the pH to 7~7 with 30% aqueous sodium hydroxide solution under ice cooling. 8. The following operations were performed under ice cooling. 27.6 parts of sodium nitrite was added and stirred for 30 minutes. 97.3 parts of 35% hydrochloric acid were gradually added in small amounts to obtain a brown solution, which was then stirred for 2 hours. An aqueous solution obtained by dissolving 25.1 parts of sulfamic acid in 250 parts of water was added to the reaction solution and stirred to obtain a suspension containing a diazonium salt.

[0327]

[0328] After adding 260 parts of water and 28.9 parts of N-methylpyrrolidone to 28.9 parts of 1-butyl-3-cyano-4-methyl-6-hydroxypyridin-2-one represented by formula (c-1), The pH was adjusted to 8-9 with 30% aqueous sodium hydroxide solution under ice cooling.

Abstract

The invention provides a colored curable resin composition which comprises a colorant, a resin, a polymerization compound, a polymerization initiator and a solvent. The colorant is that of a compound represented in formula (1) and a zinc phthalocyanine compound. The colorant can form a color filter with high clarity.

Description

technical field [0001] The present invention relates to a colored curable resin composition. Background technique [0002] Compared with self-emissive display devices such as plasma displays, display devices using color filters have a problem of lower brightness because they display images using light passing through the color filters. In order to obtain a bright and vivid image, it is required to use a color filter with high brightness. [0003] The color filter is produced from a colored curable resin composition. JP-A-2010-168531 describes a colored curable resin composition containing a zinc phthalocyanine compound and C.I. Solvent Yellow 162 as a colorant. Contents of the invention [0004] In order to obtain a bright and vivid image, it is required to use a color filter with high brightness. [0005] The conventionally known colored curable resin composition may not always be able to fully satisfy the requirements for both brightness and solvent resistance of the ...
