Abstract: A linoleum-based planar structure, a process for the preparation of such a planar structure as well as the use of the planar structure, for example, as a floor covering is provided. The linoleum-based planar structure contains flakes, including organic polymeric material, over the whole cross section of the linoleum sheet. The flakes are compatible with the linoleum base composition and have a particle size in the range of 0.5 mm to 30 mm and a thickness in the range of 1.0 ?m to 400 ?m. Such a planar structure displays a smooth plain surface without the need of any grinding step. Moreover, the incorporation of such flakes enables a broad variety of designing and patterning, particularly the development of a distinctively, coarsely patterned “spotting structure.
