摘要： Provided is a polyurethane resin powder composition for slush molding from which an outer skin for an instrument panel can be produced, the outer skin not interfering with deployment of an airbag. More specifically, provided is a polyurethane resin powder composition (D) for slush molding comprising perfectly spherical thermoplastic polyurethane resin particles (A) obtained by reacting a polyester diol component (J) and a diisocyanate component (F), a plasticizer (B), and a vinyl-type copolymer fine particles (C) having a crosslinked structure, wherein the polyester diol component (J) comprises a polyester diol (J1) comprising an aromatic dicarboxylic acid (E) and ethylene glycol as essential constituent units, a ratio of volume average particle sizes of (A) and (C), (A):(C), is 200:1 to 2000:1, and an extent of surface coverage of a surface of (A) with (C) {Equation (1)} is 20 to 80%. [Expression 1] Extent of surface coverage (%)=[number of particles of (C)]×[average cross section area of one particle of (C)]/surface area of (A)×100 (1)
