A process is disclosed for producing a coarse surface on a plastic article, comprising preparing a dispersion of fine crystalline material in a solution of a polymer from which the plastic article is made. The article is immersed into the dispersion, causing a partial solvation and softening of the surface layer coated by the dispersion. Upon removal of the solvent component of the dispersion from the article surface, the fine crystalline material is embedded into the surface of the article so as to create a textured surface suitable for gripping and the like.
