ARTIFICIAL LEATHER AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2023/013638

A1

The present invention relates to an artificial leather which is provided with a base material layer that contains a fiber base material, wherein: at least a part of the artificial leather contains a polypeptide derivative; the polypeptide derivative contains a block copolymer that has a first segment containing a polypeptide skeleton and one or more second segments that are bonded to the first segment; the polypeptide skeleton is a recombinant polypeptide skeleton or a hydrophobic polypeptide skeleton; and the second segments each have a molecule group that has a plasticizing function on the polypeptide skeleton.
