Abstract: A synthetic resin skin material and a manufacturing method thereof, the synthetic resin skin material including, in this order: a base fabric; 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); and a skin layer containing a urethane resin, wherein the synthetic resin skin material has recesses at a side of the skin layer, the recesses having a depth, in a thickness direction of the synthetic resin skin material, that extends from the skin layer as far as an inner part of the thermoplastic resin layer, past a boundary that is present between the skin layer and the thermoplastic resin layer at a non-recessed region.

Abstract: A synthetic resin skin material composite, including: a urethane resin skin material including a urethane resin skin layer provided at one surface of a substrate; and a cushion layer that is placed at a surface on an opposite side of the substrate from the surface of the urethane resin skin material at which the urethane resin skin layer is provided; in which the urethane resin skin material has recesses at a side of the urethane resin skin layer, and each of the recesses has a depth in a thickness direction of the synthetic resin skin material composite, such that the recesses extend from the urethane resin skin layer into the cushion layer beyond an interface between the urethane resin skin material and the cushion layer that is present in a region without a recess, as well as a method of producing a synthetic resin skin material composite.
