PROBLEM TO BE SOLVED: To provide pyrrolo [3,4-c] pyrrole which can be stably dispersed at a high concentration in an organic solvent, and a coloring material containing the same. SOLUTION: The coloring material according to the present invention has formulas (I) to (I). Characterized in that it contains a specific pyrrole derivative represented by the formula (V), wherein the coloring material is a plastic material, a melt, a spinning solution, a paint system, a positive type or a negative type U. V-resist, positive or negative electron beam resist, coating material, printing ink such as screen printing, gravure printing, flexographic printing or offset printing, non-impact printing ink such as ink jet printing or thermal transfer, toner or formulation Color material, in particular, a color filter for a liquid crystal display using a resist. |
