Claim 5:
6. A method for manufacturing a synthetic resin skin material, the method comprising:
forming a skin layer containing a urethane resin using a composition for forming a skin layer containing a urethane resin;
forming a thermoplastic resin layer having a storage elastic modulus at 160° C. of 2,000,000 Pa or less measured in accordance with JIS K 7244 (1998) by applying, to one side of the skin layer, a composition for forming the thermoplastic resin layer, the composition for forming the thermoplastic resin layer containing a polyvinyl chloride resin having a storage elastic modulus at 160° C. of 2,000,000 Pa or less measured in accordance with JIS K 7244 (1998), and a plasticizer in an amount of 35 to 120 parts by mass with respect to 100 parts by mass of the polyvinyl chloride resin, to form a laminate of the skin layer and the thermoplastic resin layer;
adhering a base fabric to a surface of the laminate at a side of the thermoplastic resin layer; and
bringing an embossing roller into contact with the laminate on a surface at a side of the skin layer, the laminate having the base fabric adhered thereto, to perform embossing to form recesses, wherein, in forming the recesses, recesses, having a depth, in a thickness direction of the synthetic resin skin material, that extends from the skin layer to an inner part of the base fabric, past a boundary that is present between the thermoplastic resin layer and the base fabric, are formed at the surface at the side of the skin layer of the laminate,
wherein the skin layer of the synthetic resin skin material has a thickness of from 20 to 200 μm.
