Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a perimidone ring-containing new naphthalimide compound useful as fluorescent brighteners or organic electroluminescent luminous materials, to provide a method for producing the compound and to obtain a blue fluorescent coloring matter. SOLUTION: This perimidone ring-containing naphthalimide compound is represented by structural formula (I) (wherein, R1, R2 and R3 denote each an alkyl group, an aryl group, a cycloalkyl group or an alkenyl group which may have a substituent group) and the blue fluorescent coloring matter comprises the compound. The compound is produced by reacting a compound represented by structural formula (II) with a urea derivative represented by the structural formula (III): R2NH-CO-NHR3.
