Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a novel naphthalimide compound useful as a fluorescent whitening agent and as a luminescent material for organic electroluminescent element; and a blue fluorescent pigment. SOLUTION: This naphthalimide compound is represented by formula (I) (R1 and R2 are each an optionally substituted alkyl, aryl, alkenyl or cycloalkyl group; and X is a divalent linking group). The blue fluorescent pigment comprises the naphthalimide compound.
