<p>A leather-like sheet bearing a (semi)grain finish which comprises: an entangled nonwoven fabric obtained by three-dimensionally entangling fiber bunches each comprising long microfibers; and a polymeric elastomer contained in the fabric. When the leather-like sheet bearing a (semi)grain finish is divided in the thickness direction into five equal portions composed of a surface layer, a base layer (1), a base layer (2), a base layer (3), and a back layer in this order, then the long microfibers constituting the surface layer and/or the back layer are at least partly fusion-bonded to one another, but the long microfibers constituting the interlayers are not fusion-bonded to one another. Due to such fusion-bonded state of the long microfibers, the leather-like sheet bearing a (semi)grain finish not only combines low resilience with a solid feeling which are equal to those of natural leathers, but also has practically sufficient strength and excellent performances required according to uses.</p> |
