Abstract:
The present invention relates to a photosensitive (alkali developable) coloring composition which uses a compound that has excellent heat resistance and excellent solubility in a resin composition. The present invention also relates to an optical filter which uses the photosensitive (alkali developable) coloring composition especially a color filter that does not cause a luminance decrease and is suitable for image display devices such as liquid crystal display panels. Specifically the present invention relates to: a photosensitive (alkali developable) coloring composition which contains (A) a dye that contains at least one compound that is represented by one of general formulae (1) (4) (B) a polymerizable compound which has an ethylenically unsaturated bond or (B ) a polymerizable compound which is alkali developable and has an ethylenically unsaturated bond and (C) a photopolymerization initiator; and a use of the photosensitive (alkali developable) coloring composition. The compound represented by one of general formulae (1) (4) is as set forth in the description.
Abstract:
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.

Specifically, the present invention provides a color tone correcting agent including a squarylium compound represented by the general formula (1), a novel squarylium compound which is represented by the general formula (4) and is preferable as the color tone correcting agent, and an optical filter including the color tone correcting agent. The general formula (1) and (4) are each as defined in the specification.
Abstract:
The color conversion filter of the present invention contains at least one kind of squarylium dye that radiates fluorescence light, has a wavelength conversion capability, absorbs light in an unneeded wavelength region, radiates fluorescence light in a preferable wavelength region, and does not allow decrease in brightness, and thus is preferable for color conversion light-emitting devices, photoelectric conversion devices and the like. Specifically, the color conversion filter of the present invention has an absorption having a high intensity in the range of 570 to 600 nm, and thus is preferable for use in a color conversion filter that radiates fluorescence light having a high intensity in the range of 600 to 780 nm.
