Abstract: A composition for an optical waveguide is cured into a sheet to give a cured product. A difference in light transmittance with respect to light having a wavelength of 450 nm is 15% or less between this cured product and this cured product after retention in atmosphere at 175° C. for 40 hours, the light transmittance being calculated in terms of the cured product at a thickness of 50 μm.

Abstract: An imaging apparatus includes a first electrode, a second electrode, and a photoelectric conversion layer located between the first electrode and the second electrode. The photoelectric conversion layer contains a first material, a second material, and a third material. The first material is a fullerene or a fullerene derivative. The second material is a donor-like organic semiconductor material. The average absorption coefficient in the visible light wavelength range of the third material is less than the average absorption coefficient in the visible light wavelength range of the first material.
