Abstract
Provided is a photosensitive resin composition that is developable with an aqueous alkaline solution and is suitable for the production of a color filter for an image sensor. The composition comprises an alkali-soluble resin, a photopolymerizable monomer, a photopolymerization initiator, colorants and a solvent. As the colorants, a pigment and a dye are used in combination. The use of the composition enables the formation of fine pixels that exhibit excellent color reproduction and contrast. Therefore, the composition can be used to produce a high-resolution color filter for an image sensor.
