NOVELTY - An ultraviolet ray absorber composition comprises ultraviolet ray absorber having heteroatom-containing compound (2 or B-I), and benzene-containing compound (TS-I) or nitrogen-containing compound (TS-II).    USE - Ultraviolet ray absorber composition is used for ultraviolet absorber dispersoid, ultraviolet absorber solution and polymer material (all claimed). Can also be used for packaging material, container, coating material, coating film, ink, fiber, building material, recording medium, image display apparatus and cover for solar cell.    ADVANTAGE - The ultraviolet ray absorber composition has excellent ultraviolet absorptivity for long period of time, and light resistance.    DETAILED DESCRIPTION - An ultraviolet ray absorber composition comprises ultraviolet ray absorber having heteroatom-containing compound of formula (2 or B-I), and benzene-containing compound of formula (TS-I) or nitrogen-containing compound of formula (TS-II).    A21,A22=heteroatom;    Y21,Y22=hydrogen or monovalent substituent, where at lest one of Y21 and Y22 is substituent having Hammet substituent constant of 0.2 or more, and combined to form ring;    B'=atomic group bonded with A21, A22 and carbon atom to form 5 or 6-membered ring;    Rb1-Rb6=hydrogen or monovalent substitutent;    Xb1-Xb4=heteroatom;    R91=hydrogen, optionally substituted (alkyl, alkenyl, aryl, heterocyclic, acyl, alkenyloxy carbonyl or alkenyloxy carbonyl, aryloxy carbonyl, alkylsulfonyl and arylsulfonyl) or silicon-containing group of formula: -Si(R97)(R98)(R99);    R97-R99=alkyl, alkenyl, aryl, alkoxy or alkenyloxy, and aryloxy;    X91=oxygen, sulfur or -N(-R100);    R100=R91;    R92-R96=hydrogen or substitutent, where all of R91-R96 and R100 do not represent hydrogen in molecule and the total number of carbon atoms in all of R91 to R96 and R100 is 10 or more;    R101-R104=hydrogen, optionally substituted (alkyl or alkenyl), where R101 and R102 or R103 and R104 optionally bonded to form 5-7-membered ring;    X101=hydrogen, optionally substituted (alkyl, alkenyl, alkyloxy, alkenyloxy, alkyloxy carbonyl or alkenyloxy carbonyl, aryloxy carbonyl, acyl, acyloxy, alkyloxy carbonyloxy, alkenyloxy carbonyloxy, aryloxy carbonyloxy, alkyl sulfonyl or alkenyl sulfonyl, aryl sulfonyl, alkyl sulfinyl or alkenyl sulfinyl, aryl sulfinyl, sulfamoyl, or carbamoyl), hydroxyl or oxy radical;and    X102=heteroatom bonded to form 5-7-membered ring.
