Abstract
A method for producing surface coatings on articles, such as stick surfaces, coats at least a part of the surface with a coating. The coating has expandable particles. One surface region of the coating is treated so that the particles expand, while another surface region of the coating remains untreated. The corresponding article, such as a stick, has a surface provided at least partly with a coating with said expandable particles. The particles of the coating are expanded in one surface region thereof and unexpanded in another surface region. The former surface region projects beyond the surface of the latter surface region.
