| 摘要 |
The present invention provides a dye that is excellent in solubility and heat-resistance, and a novel compound that is suitable for the dye, and specifically provides a yellow dye having a maximum absorption wavelength in the region of 420 to 470 nm. Furthermore, the present invention provides a colored (alkali-developable) photosensitive composition and an optical filter using the dye, and specifically provides a color filter that does not decrease luminance and thus is preferable for an image display device such as a liquid crystal display panel. Specifically, the present invention provides a novel compound represented by the following general formula (1), a dye using the compound, and a colored (alkali-developable) photosensitive composition and a color filter. The content of the above-mentioned general formula (1) is as described in the description. |
