PROBLEM TO BE SOLVED: To provide a polyurethane resin-based material for slush molding, having less temporal coloring (discoloration) and gloss rising. SOLUTION: The material for slush molding comprises a thermoplastic polyurethane resin (A) comprising, as essential components, an aliphatic diisocyanate (a) having an asymmetric structure and preferably a low molecular aliphatic diamine (b1) having an asymmetric structure and comprises a compound having two or more radical-polymerizable unsaturated groups in a molecule, preferably, an ester (B) of (meth)acrylic acid with polyhydric alcohols.
