PROBLEM TO BE SOLVED: To obtain a powder composition for slush molding, having weatherability, chemical resistance, adhesiveness, flexibility and abrasion resistance and excellent balance of powder flowability during molding, melt flowability (moldability) and mold release characteristics. SOLUTION: The method for producing a powder composition for slush molding comprises blending 100 pts.wt. of a thermoplastic elastomer composition powder (X) having a particle diameter of 1-1,000μm composed of an acrylic block copolymer (A) having a fixed structure and an acrylic polymer (B) having at least≥1.1 reactive function groups (C) in one molecule with 0.01-5 pts.wt. of a powder pigment (D), 0.01-5 pts.wt. of an inorganic pigment dispersant (E), 0.01-5 pts.wt. of a hydroxy group-modified and/or carboxy group-modified silicone oil (F) and 0.5-20 pts.wt. of organic particles (Y) having particle diameters of 0.1-30μm and smaller than those of the thermoplastic elastomer composition powder (X) while controlling the blend at -10°C to 60°C.
