<P>PROBLEM TO BE SOLVED: To provide a UV-ray absorber composition not generating precipitation of the UV-ray absorber in use or bleeding out by usage for a long period of time, being excellent in long wavelength UV-ray absorption ability, and being excellent in light resistance while maintaining the absorption ability for a long period of time. <P>SOLUTION: The UV-ray absorber composition includes at least one kind of a compound represented by formula (1) and a compound having a specific structure. [In the formula, R<SP POS="POST">1a</SP>, R<SP POS="POST">1b</SP>, R<SP POS="POST">1c</SP>, R<SP POS="POST">1d</SP>and R<SP POS="POST">1e</SP>each independently represents a hydrogen atom or a mono-valent substituent except a hydroxy group, at least one of the substituents represents a substituent having a positive σp value of the Hammett's rule, and the substituents may be mutually bonded to form a ring, and R<SP POS="POST">1g</SP>, R<SP POS="POST">1h</SP>, R<SP POS="POST">1i</SP>, R<SP POS="POST">1j</SP>, R<SP POS="POST">1k</SP>, R<SP POS="POST">1m</SP>, R<SP POS="POST">1n</SP>and R<SP POS="POST">1p</SP>each independently represents a hydrogen atom or a mono-valent substituent, and both the substituents may be mutually bonded to form a ring]. <P>COPYRIGHT: (C)2012,JPO&INPIT |
