Problems solved by technology

[0011] However, when a pixel containing these colorants was manufactured and its chromaticity was measured, when the pixel was formed, the luminance decreased after drying at a high temperature of 230°C compared to before drying at a high temperature
Dye-based color materials are poor in heat resistance compared to pigments that have been conventionally used, therefore, sufficient brightness cannot be obtained due to heat treatment
[0012] In addition, Korean Patent Application Publication No. 10-2013-0082469 discloses a colored photosensitive resin composition with improved heat resistance, however, there arises problems of a decrease in dispersion stability and a decrease in brightness due to heat treatment

preparation example Construction

[0223] The preparation method of the colored photosensitive resin composition of this invention is as follows.

[0224] First, the colorant (A) is mixed with the solvent (F) and dispersed using a bead mill or the like until the average particle diameter of the pigment becomes about 0.2 μm or less. Here, the pigment dispersant (a2) and a part or all of the alkali-soluble resin (B) may be mixed with the solvent (F), and dissolved or dispersed therein, if necessary.

[0225] The remaining alkali-soluble resin (B), the photo- or thermally polymerizable compound (C) including the isocyanurate compound of Chemical Formula 1, the photopolymerizable monomer (D) are further added to the mixed coloring material ), a photopolymerization initiator (E), an additive (G) as required, and further adding a solvent (F) so as to have a specific concentration, and the colored photosensitive resin composition of the present invention can be prepared.

[0226] In addition, the present invention pr...

Synthetic example 1

[0239] 43.4 parts by weight of isocyanuric acid and 500 parts by weight of toluene were put into a 4-neck round bottom flask including a cooling pipe and a stirrer, and while stirring the mixture, 0.4 parts by weight of hydroxide was introduced thereto Barium, 27.5 parts by weight of formaldehyde and 29.1 parts by weight of acrylic acid.

[0240] The reflux reaction continued for 12 hours and was monitored by TLC to identify completion of the reaction.

[0241] After the temperature of the reactor was lowered to room temperature, the organic solution was washed three times with water and ethyl acetate, and the organic layer was separated and dried over anhydrous magnesium sulfate. The solvent was removed under vacuum to obtain 83.2 parts by weight (83% yield) of the compound of the following Chemical Formula 5 as a white solid.

Synthetic example 2

[0245] 35.9 parts by weight of isocyanuric acid and 500 parts by weight of toluene were put into a 4-neck round bottom flask including a cooling pipe and a stirrer, and while stirring the mixture, 0.4 parts by weight of hydroxide was introduced thereto Barium, 10.1 parts by weight of formaldehyde, and 54.0 parts by weight of acrylic acid.

[0246] The reflux reaction continued for 12 hours and was monitored by TLC to identify completion of the reaction.

[0247] After the temperature of the reactor was lowered to room temperature, the organic solution was washed three times with water and ethyl acetate, and the organic layer was separated and dried over anhydrous magnesium sulfate. The solvent was removed under vacuum to obtain 85.1 parts by weight (85% yield) of the compound of the following Chemical Formula 6 as a white solid.
