PROBLEM TO BE SOLVED: To provide a negative type photosensitive compsn. for color filter which is not affected by oxygen at the time of exposure, has high sensitivity and excellent chemical resistance and makes image formation possible even at a high pigment concn. by incorporating an acrylic resin having a carboxyl group, a photo-acid generating agent, a crosslinking agent having a curing effect by the effect of an acid and pigments. SOLUTION: This compsn. contains the acrylic resin having the carboxyl group, the photo-acid generating agent, the crosslinking agent having the curing effect by the effect of the acid, the pigments and a solvent. A copolymer of a monomer having the carboxyl group, such as (meth)acrylic acid and meleic (anhydride) and a comonomer copolmeriable therewith is used as the acrylic resin having the carboxyl group. The photo-acid generating agent is a compd. to generate the acid by UV light and includes an org. halogen compd., onium salt, etc. The crosslinking agent having the curing effect by the effect of the acid includes the compds. acted with melamine, benzoguanamine, etc. The pigments include org. pigments, such as barium sulfate and sulfate, etc. |
