Zusammenfassung:PROBLEM TO BE SOLVED: To provide a composition containing a cross-linking agent for minimizing the deterioration of polyurethane foams in high humidity ageing conditions, and to provide a polyurethane foam using the same. SOLUTION: This composition comprises a nonvolatile tertiary amine urethane catalyst and an amideamine and/or an imidazoline cross-linking additive. A foam prepared by the reaction of a polyol with an organic isocyanate in the presence of the components exhibits excellent resistance against the deterioration of physical properties, when aged in a high humidity.
