ABSTRACT:
An ultraviolet absorber composition is provided and includes: a compound represented by formula (I); and an ultraviolet absorber having a maximum absorption at a wavelength of from 340 to 400 nm:R1a, R1b, R1c, R1d, R1e, R1f, R1g, R1h, R1i, and R1jeach independently represent a hydrogen atom or a monovalent substituent except OH, or adjacent two of R1a, R1b, R1c, R1d, R1e, R1f, R1g, R1h, R1i, and R1jmay be taken together to form a ring; R1k, R1m, R1n, and R1peach independently represent a hydrogen atom or a monovalent substituent, or adjacent two of R1k, R1m, R1n, and R1pmay be taken together to form a ring; and at least one of R1a, R1b, R1c, R1d, R1e, R1f, R1g, R1h, R1i, R1j, R1k, R1m, R1n, and R1pis a substituent having a positive σp value in Hammett equation.
