ABSTRACT:
A surface layer of an interior article, comprising a surface layer body formed of a synthetic resin and endowed with high extensibility, and a surface skin formed on the surface layer body and having a softening temperature lower than that of the surface layer body, with an uneven pattern being formed on the surface skin. Because of its lower softening temperature, the surface skin is held in a softer condition during a forming operation, so it is possible to form a clear uneven pattern positively on the surface skin.
