Abstract
A curable resin composition for a lens, including a coloring agent A having a maximal absorption at a wavelength of 520 to 620 nm, in which a wavelength dispersion WD of a cured product of the composition, which is calculated by the following expression (X), is 2.0×10or more; a cured product formed of the curable resin composition for a lens; a diffractive optical element; and a multilayer diffractive optical element.WD=((1129))/(1129−656) Expression (X)In the expression, nC represents a refractive index at a wavelength of 656 nm and n(1129) represents a refractive index at a wavelength of 1129 nm.
