PROBLEM TO BE SOLVED: To provide a photosensitive coloring composition capable of improving the dispersibility and dispersion stability of a pigment. (A) A base number of 10 to 100 mg KOH / g of a dispersant, (b) a binder polymer containing at least the structural unit represented by the chemical formula 1, having an acid value of 10 to 60 mgKOH / g, and a weight average molecular weight in terms of polystyrene of 5,000 to 70,000, (c) a pigment, and (d) photopolymerization. Monomer, Excellent pigment dispersibility and dispersion stability were exhibited by containing (e) a photopolymerizable initiator and (f) a solvent. Photosensitive coloring composition. (In the chemical formula 1, R 1 may be the same or different, and represents a hydrogen atom or a hydrocarbon group. R 1 represents an aliphatic group having 1 to 18 carbon atoms or an aromatic group having 6 to 12 carbon atoms. ) |
