Abstract

A method is disclsed for surface improving sheet-like substrates to impart them with a marbleized effect. A transfer sheet is pressed on the substrate at elevated temperatures. The transfer sheet is comprised of superimposed layers of synthetic resin. The resin layer closest to the backing of the transfer sheet is devoid of pigments, while the resin layer adjacent the pigment free layer comprises 2 to 40% by weight, calculated on the amount of resin, of a flake-like pigment. The pressing of the transfer sheet against the substrate is carried out with a press tool devoid of surface pattern and having a generally flat press surface.
