The present invention is liquid crystal display without lowering the solubility and coloring with an excellent compound Heat resistance (alkali developability) relates to a photosensitive composition, the colored (alkali developability) An optical filter using a photosensitive composition, in particular luminance in the resin composition in the image display device of the panel or the like relates to the appropriate color filter. Specifically, the present invention of the general formula (1) to (4), which dye (A) obtained by containing at least one kinds of the compounds represented by one, polymerizable compound having an ethylenically unsaturated bond (B), or an alkaline developer of the castle with the present invention relates to an ethylene polymerization having an unsaturated bond compound (B ') and colored (alkali-developing property), the photosensitive composition and the use of a photopolymerization initiator (C). For the compound represented by any one of formulas (1) to (4) it is as described in the specification.
