Abstract

Disclosed is a colored (alkali-developable) photosensitive composition using a compound that is excellent in solubility and heat-resistance in a resin composition, and also relates to an optical filter using the colored (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, disclosed is a colored (alkali-developable) photosensitive composition containing (A) a dye that contains at least one kind of compound represented by any of the general formulas (1) to (4), (B) a polymerizable compound having an ethylenically unsaturated bond or (B′) a polymerizable compound having an ethylenically unsaturated bond, which has alkali-developability, and (C) a photopolymerization initiator, and use of the composition. The compound represented by any of the general formulas (1) to (4) is as described.
