[0320] Next, the present invention will be described more concretely with reference to examples. Unless otherwise specified, "%" and "part" in an example are mass % and a mass part.

[0321] After adding 200 parts of water to 10 parts of m-toluidine-4-sulfonic acid (the compound represented by the formula (a-2)), it adjusted to pH 7-8 with 30% sodium hydroxide aqueous solution under ice-cooling. The following operations were performed under ice cooling. Add 11.1 parts of sodium nitrite and stir for 30 minutes. After gradually adding 39 parts of 35% hydrochloric acid to prepare a brown solution, the mixture was stirred for 2 hours. An aqueous solution obtained by dissolving 10.1 parts of amide sulfuric acid in 101 parts of water was added to the reaction solution and stirred to obtain a suspension containing a diazonium salt.

[0323] Add 125 parts of water and N - After 25 parts of methylpyrrolidone, adjust the pH to 8-9 with 30% aqueous sodium hydroxide soluti...

Synthetic example 2

[0364] Nitrogen gas was flowed in at 0.02 L / min into a flask equipped with a reflux condenser, a dropping funnel, and a stirrer to make a nitrogen atmosphere, 305 parts by mass of ethyl lactate was added, and it was heated to 70° C. while stirring.

[0365] Next, dissolve in 60 mass parts of acrylic acid, acrylic acid 3,4-epoxytricyclic [5.2.1.0 2.6 ] decyl ester (the compound represented by the formula (I-1) and the compound represented by the formula (II-1) are mixed in a molar ratio of 50:50.) Prepare a solution in 240 parts by mass and 140 parts by mass of ethyl lactate, This solution was dropped into a flask kept at 70° C. using a dropping funnel over 4 hours.

[0366]

[0367] On the other hand, 30 parts by mass of the polymerization initiator 2,2'-azobis(2,4-dimethylvaleronitrile) was dissolved in 225 parts by mass of ethyl lactate over 4 hours using another dropping funnel. The solution was added dropwise to the flask. After the titration of the solution of the po...

Abstract

The invention provides a colored curable resin composition, comprising a colorant, a resin, a polymerized compound and a polymerization initiator, wherein the colorant includes copper chloride phthalocyanine dye and a yellow dye; the content of the yellow dye is more than 1 mass % and below 65 % relative to a total content of the colorant. According to the invention, the invention provides a colored curable resin composition which can manufacture blue-green color filters.

Description

technical field [0001] The present invention relates to a colored curable resin composition. Background technique [0002] The colored curable resin composition can be used for production of color filters used in display devices such as liquid crystal display panels, electroluminescence panels, and plasma display panels. As such a colored curable resin composition, a colored curable resin composition containing only C.I. Pigment Green 7 and C.I. Pigment Yellow 138 as a colorant is known (for example: JP2009-265641-A). [0003] In the case of producing a cyan color filter from a conventionally known colored curable resin composition, the brightness of the color filter may not necessarily be sufficiently satisfactory. Contents of the invention [0004] The present invention includes the following inventions. [0005] [1] A colored curable resin composition containing a colorant, a resin, a polymerizable compound, and a polymerization initiator, wherein the colorant contain...
