<P>PROBLEM TO BE SOLVED: To provide a flexible polyurethane foam that uses an aromatic polyisocyanate having excellent reactivity and foam stability, prevents discoloration by nitrogen oxides and discoloration by heat, etc., during wetting. <P>SOLUTION: The flexible polyurethane foam is produced from a foaming raw material comprising a polyol, an aromatic polyisocyanate, a blowing agent and a catalyst. The foaming raw material comprises a phosphorus-based antioxidant and a hindered amine-based light stabilizer. The weight ratio of the phosphorus-based antioxidant to the hindered amine-based light stabilizer in the foaming raw material is preferably 1:2-10:1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
