Provided is a vinyl chloride resin composition for powder molding with which it is possible to form a vinyl chloride resin molded product having excellent alcohol resistance and low-temperature flexibility. The vinyl chloride resin composition for powder molding contains: (a) a vinyl chloride resin; and (b) a 3-methyl-1,5-pentanediol-sebacic acid polyester that includes a sebacic acid-derived structural unit and a 3-methyl-1,5-pentanediol-derived structural unit. The vinyl chloride resin composition for powder molding is preferably used for powder slush molding.

The present invention relates to a powder slush molded body of a polyvinyl chloride composition, the polyvinyl chloride composition containing a polyvinyl chloride, a plasticizer, and an acrylic polymer. The polyvinyl chloride composition contains the plasticizer in an amount of 110 parts by mass or more and 150 parts by mass or less with respect to 100 parts by mass of the polyvinyl chloride. When a cross section of the powder slush molded body extending in parallel with a thickness direction is observed under an optical microscope using reflected light, irregular scale-like polyvinyl chloride particles having a long diameter of 30 μm or more and 500 μm or less are continuous with one another via interfacial portions, and the number of aggregated particles of the acrylic polymer having a long diameter of 30 μm or more and 100 μm or less is 10 particles/mm.sup.2 or less. Thus, provided are a powder slush molded body of a polyvinyl chloride composition having high flexibility after heat aging as well as favorable surface characteristics, and a laminate.
