Provided is a light-absorbing composition having a transmittance of 0.1% or more in the wavelength range of 380-1000 nm, and having a quadratic function represented by the following formula (1) when the transmittance values of all wavelengths are calculated on the basis of the least square method in a transmittance graph in which the horizontal axis represents a wavelength of 380-1000 nm and the vertical axis represents the transmittance: y = ax2 + bx + c (R2gt; 0.8), alt; dE-7 (d = n), blt; c = n, in the formula, R2 is a coefficient of determination and is a value obtained by squaring a sample correlation coefficient r, and n is an integer from 1 to 9. 本发明提供一种光吸收组合物，其中，在380至1000nm的波长范围内具有0.1％以上的透射率，当在横轴表示380至1000nm的波长且纵轴表示透射率的透射率曲线图中，基于最小二乘法计算所有波长的透射率值时，具有由下式(1)表示的二次函数：(式1)y＝ax2+bx+c(R2>0.8)，|a|<dE-7(d＝n)，|b|<0.005，c＝n在式中，R2为可决系数，是通过对样本相关系数r进行平方得到的值，n为1至9的整数。
