Problems solved by technology

[0008] However, if the dye concentration is increased, there are problems that the pigment can be seen to be eluted or precipitated from the formed pixels after film formation, and in the case of heat treatment (post-baking) after film formation, the gap between adjacent pixels It is easy to mix colors between the upper and lower layers in the stacked structure
[0010] However, the triarylmethane dyes described in these documents are still not satisfactory in terms of heat resistance.
[0011] In addition, Patent Document 3 discloses a xanthilium salt useful for medical use, but neither describes nor teaches that the xanthilium salt can be used in a colored photosensitive composition for color filters.

[0161]

[0162] 0.01 mol of compound S-1 represented by the following chemical formula, 0.02 mol of diethylaminophenol, and 0.03 mol of sulfuric acid were mixed, and stirred at 140° C. for 8 hours. The reaction solution was added dropwise to an aqueous sodium hydroxide solution, the organic matter was extracted with toluene and washed with water three times, and the solvent was distilled off from the organic layer. The residue was purified by silica gel column chromatography (developing solvent: chloroform) to obtain 0.005 mol of a colorless product (52% yield).
