Light-absorbing composition, light-absorbing film, method for producing light-absorbing film, and optical filter

An optical filter comprising:

• a light-absorbing film, wherein
• the optical filter has a first transmission spectrum for light incident at an incident angle of 0°, the first transmission spectrum satisfying the following conditions (I-a), (II-a), and (III-a):
• (I-a) a maximum transmittance in a wavelength range of 300 nm to 380 nm is 3% or less;
• (II-a) a first cutoff wavelength λUV at which transmittance is 50% in a wavelength range of 300 nm to 520 nm is in a range of 405 nm to 500 nm;
• and
• (III-a) an average transmittance in a wavelength range of 550 nm to 570 nm is 87% or more.
