摘要:
A leather-like sheet material including a fibrous substrate and an elastomeric film layer which are bonded to each other with a silicone-compound-containing water-soluble or water-dispersible adhesive layer of an elastic polymer, and the leather-like sheet material is produced by a process for the production of a leather-like sheet material by attaching the fibrous substrate and the elastomeric film layer, which process includes applying a water solution or water dispersion of an elastic polymer, the water solution or water dispersion containing a silicone compound, to the attachment surface of one of the fibrous substrate and the elastomeric film layer and drying the applied solution or dispersion. According to this invention, there is provided a leather-like sheet material excellent in abrasion resistance and at the same time excellent in tenacity against peeling and flexibility, and a production process thereof.
