Ultraviolet-curable black resin composition, black resin cured product, material for manufacturing electronic component, and electronic component

Abstract

Provided are: an ultraviolet-curable black resin composition including a black pigment, a photopolymerizable compound, and a photopolymerization initiator, in which 8′(2) at a wavelength of λ nm is defined as ε′(λ)=OD(λ)/(c×1), where OD(λ) is an optical density at the wavelength of λ nm, c is a pigment concentration, and 1 is an optical path length, and a ratio ε′(550)/c′(365) of ε′(550) for light at a wavelength of 550 nm to ε′(365) for light at a wavelength of 365 nm is set to a range of 1.00 to 2.00; a black resin cured product; and a material for manufacturing an electronic component and an electronic component, both including the above-described ultraviolet-curable black resin composition and black resin cured product.
