As a negative photosensitive coloring composition containing (A) a white pigment, (B) a siloxane resin, (C) a photoinitiator, (D) a photopolymerizable compound and (E) an organic solvent, the (B) siloxane resin is at least the following general The repeating unit represented by formula (1) and/or the repeating unit represented by the following general formula (2) and the repeating unit represented by the following general formula (3) are included, and all repeating units of the (B) siloxane resin Among them, a negative photosensitive coloring composition containing 40 to 80 mol% in total of the repeating unit represented by the following general formula (1) and the repeating unit represented by the following general formula (2); [In General Formulas (1) to (3), R 1 represents an alkyl group having 1 to 10 carbon atoms, alkenyl group, aryl group or arylalkyl group in which all or part of hydrogen is substituted with fluorine; R 2 represents a single bond, -O-, -CH 2 -CO-, -CO- or -O-CO-; R 3 represents a monovalent organic group having 1 to 20 carbon atoms; R 4 may be the same or different, and represent a monovalent organic group having 1 to 20 carbon atoms.] Even if it is a thick film, a negative photosensitive coloring composition capable of forming a cured film having high resolution and high reflectivity and excellent heat resistance is provided. |
