Abstract
The present invention provides a dye that is excellent in solubility and excellent in heat resistance and a novel compound that is preferable for the dye, and specifically provides a yellow dye having a wavelength of maximum absorption in the region of 400 to 450 nm, and also provides a coloring (alkali-developable) photosensitive composition using the above-mentioned dye, and an optical filter using the above-mentioned coloring (alkali-developable) photosensitive composition, specifically a color filter that does not decrease luminance and thus is preferable for image display devices such as liquid crystal display panels. Specifically, a compound represented by the following general formula (1) is used as the dye. The content of the above-mentioned general formula (1) is as described in the description.
