Abstract

An article, such as a door, is made from a colored water-extended thermoplastic polymeric material, and is provided with a decorated pattern by fusion of a surface layer to form a non-cellular layer, the depth of fusion being different in different parts so that the depth of color is correspondingly different. The variation in color intensity provides a decorative pattern, and fusion of the cellular material is effected by pressing with a die in the shape of the desired pattern.
