Abstract: A colorant which has high heat resistance and thus causes neither discoloration nor fading even when exposed for a long period of time under long-term high-temperature conditions, and which has excellent bleed resistance and sublimation resistance and thus causes neither color migration to molds or other resin components, nor deterioration of physical properties of a thermoplastic resin added thereto. The colorant includes at least one compound represented by a specified chemical formula (1a), at least one compound represented by a specified chemical formula (1b), and/or at least one compound represented by a specified chemical formula (1c).
