PROBLEM TO BE SOLVED: To provide an ultraviolet light-absorbing pigment mixture having an ultraviolet light absorptivity over a wide wavelength range, while cutting the ultraviolet light to further longer wavelength side, inhibiting its coloration as much as possible, extremely excellent in light fastness, and in the case of adding the same to a resin, etc., capable of imparting the ultraviolet light absorptivity over a wide wavelength range and other various physical properties effectively. SOLUTION: An ultraviolet light adsorbent composition contains at least one ultraviolet light adsorbent (A) expressed by general formula (1) [wherein, Het<SP>1</SP>is a divalent 5- or 6-membered ring aromatic heterocyclic residue; X<SP>a</SP>to X<SP>d</SP>are each independently a hetero atom; Y<SP>a</SP>to Y<SP>f</SP>are each independently a hetero atom or a carbon atom; and the ring bonding with the Het<SP>1</SP>may have a double bond] and at least one ultraviolet light adsorbent (B) which is a compound having an adsorptivity at the 320 nm of≥20% of the adsorptivity at an absorption maximum wavelength in a range of 270 to 400 nm and having a maximum absorbing wavelength of≤380 nm.
