HETEROCYCLIC COMPOUND, ULTRAVIOLET RAY ABSORBENT, AND COMPOSITION COMPRISING THE ULTRAVIOLET RAY ABSORBENT

摘要

A compound represented by formula (I-1):wherein R²¹, R²², R²³ and R²⁴ each independently represent a hydrogen atom or a monovalent substituent, with the proviso that compounds, in which R²¹, R²², R²³ and R²⁴ each are an alkylthio group, are excluded; R²¹ and R²² and/or R²³ and R²⁴ each may bond to each other to form a ring, with the proviso that compounds, in which the formed ring is a dithiol ring or a dithiolane ring, are excluded;R²⁵ and R²⁶ each independently represent a hydrogen atom or a monovalent substituent; X²¹, X²², X²³ and X²⁴ each independently represent a hetero atom;compounds, wherein R²¹, R²², R²³ and R²⁴ each represent a cyan group; X²¹, X²², X²³ and X²⁴ each represent a sulfur atom; and R²⁵ and R²⁶ each represent a hydroxyl group or a hydrogen atom, are excluded; andcompounds, wherein R²¹ and R²³ each represent a hydrogen atom; R²² and R²⁴ each represent an arylcarbonyl group; X²¹, X²¹, X²³ and X²⁴ each represent a sulfur atom; and R²⁵ and R²⁶ each represent a hydroxyl group, are excluded; and an ultraviolet absorbent, which has molecular weight of 10,000 or less and molar extinction coefficient at the maximum absorption wavelength of the ultraviolet absorbent of 80,000 or more.
