Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a flexible polyurethane foam as a packing material for a lighting fixture capable of effectively suppressing the discoloration of a ceiling face or wall paper or the like even if adhered to the wall paper for a long period of time. SOLUTION: The flexible polyurethane foam is obtained by foaming a polyol and poly-isocyanate compound with an amine based catalyst, and N, N-dimethylaminoalkyl urea compound is used as the amine catalyst. The packing material for the lighting fixture is composed of the flexible polyurethane foam and superior in discoloration resistance, and especially polyol contains vinyl polymer containing polyoxyalkylene polyol.
