Abstract:
A thermosetting coloring composition for manufacturing a color filter for a solid-state imaging element provided with a colored pattern formed by patterning a colored layer by dry etching is provided. The composition contains a pigment (A), a dispersant (B), a thermosetting compound (C), and a solvent (D). A ratio of the pigment (A) to a total solid content of the thermosetting coloring composition is 50 mass percent or more. The dispersant (B) contains a dispersant (b1) having an acidic functional group and/or a dispersant (b2) having a basic functional group. The thermosetting compound (C) contains a glycidyl therified epoxy compound of sorbitol.
