<P>PROBLEM TO BE SOLVED: To provide an ultraviolet light absorbing material having excellent long wavelength ultraviolet absorbency, and excellent light resistance without changing the absorbency over a long period of time. Ž<P>SOLUTION: The ultraviolet light absorbing material comprises a compound represented by general formula (1) (wherein X<SP>1</SP>and X<SP>2</SP>are each independently oxygen, sulfur or -NR<SP>17</SP>-; and R<SP>11</SP>, R<SP>12</SP>, R<SP>13</SP>, R<SP>14</SP>, R<SP>15</SP>, R<SP>16</SP>and R<SP>17</SP>are each independently hydrogen or a monovalent substituent).
