PROBLEM TO BE SOLVED: To provide excellent rotational moldings and a method for manufacturing the same, in which raw materials therefor are suitably used in the rotational molding such as the powder-slush method that can manufacture good automobile interior materials and no substances with high environmental loads such as chlorine-based substances are used, and which are excellent in demolding property, scratch resistance and correspondence to complicated shapes of the moldings obtained. SOLUTION: A polyol and an isocyanate are used as main raw materials, to which a mixed catalyst comprising a metal acetylacetonate and acetylacetone are used, wherein the mixed catalyst exhibits catalytic activity when heated to a certain temperature or above.
