摘要:
A photosensitive coloring composition includes a magenta pigment having an average primary particle diameter of 50 nm or less, a polymerizable compound, a photopolymerization initiator, and an ultraviolet absorber, in which the magenta pigment has a maximum absorption wavelength in a range of 500 to 600 nm, and in a case where an absorbance of the maximum absorption wavelength is 1, a wavelength at which an absorbance is 0.5 is 450 nm or more on a side where a wavelength is shorter than the maximum absorption wavelength and is 650 nm or less on a side where a wavelength is longer than the maximum absorption wavelength.
