| 摘要 |
The present invention addresses the problem of providing an easily manufactured resin composition which exhibits near-infrared fluorescence and has high luminescence quantum yield, and a molded article thereof. The present invention is a resin composition containing a resin and a near-infrared fluorescent pigment comprising at least one type of compound selected from the group consisting of compounds represented by general formulas (I1)-(I4), the maximum fluorescence wavelength of the resin composition being at least 650 nm. (In the formulas, Ra and Rb, Rc and Rd, Rh and Ri, and Rj and Rk form rings together with a nitrogen atom to which each thereof is bonded; Re and Rf represent halogen atoms or oxygen atoms; Rl, Rm, Rn, and Ro each independently represents a halogen atom, a C1-20 alkyl group, a C1-20 alkoxy group, an aryl group, or a heteroaryl group; Rg, Rr, and Rs represent hydrogen atoms or electron-accepting groups; and Rp and Rq each independently represents a hydrogen atom, a halogen atom, a C1-20 alkyl group, a C1-20 alkoxy group, an aryl group, or a heteroaryl group.) |
