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.

Abstract: Disclosed is a linoleum-based floor covering with improved flame-retardant properties, whose useful layer contains at least one flame retardant from the group of expandable graphites. Additionally disclosed is a method for producing linoleum-based floor-coverings with structures for creating colored patterns and to a cork-based floor covering with improved flame-retardant properties.

Abstract: A flexible floor covering with regenerative, soiling-resistant surfaces is disclosed, comprising a matrix based on natural or synthetic materials an at least one substance incompatible with said matrix. Said flexible floor covering preferably comprises a surface with a pre-determined structure and a matrix in which a particulate material harder than the matrix itself is embedded. The floor covering is characterized in having an improved soiling property and an increased wear resistance.

Abstract: The present invention relates to a linoleum-based floor covering with improved flame retardant properties, comprising at least one layer of linoleum, which contains at least one silicon-containing inorganic compound as a flame retardant in an amount of up to 40% by weight relative to the weight of the linoleum layer, and to a method for producing the same. The invention further relates to a cork-based floor covering with improved flame retardant properties, comprising at least one silicon-containing inorganic compound as a flame retardant in an amount of up to 40% by weight relative to the amount of the cork layer.

Abstract: The invention relates to a linoleum-based floor covering with improved flame-retardant properties, whose useful layer contains at least one flame retardant from the group of expandable graphites. The invention also relates to a method for producing linoleum-based floor-coverings with novel structures for creating coloured patterns and to a cork-based floor covering with improved flame-retardant properties.

Abstract: The invention relates to a continuous method for producing a cross-linked unsaturated fatty acid-based or fatty acid ester-based bonding agent, an elastic bonding agent produced according to said method and the use of said elastic bonding agent.

Abstract: The present invention relates to 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. The linoleum-based planar structure according to the present invention is particularly characterized by containing over the whole cross section flakes comprising an organic polymeric material, the flakes being compatible with the linoleum base composition and having a particle size in the range of 0.5 to 30 mm and a thickness in the range of 1.0 to 400 &mgr;m. Such a planar structure according to the present invention 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”.

Abstract: The present invention relates to a floor covering that causes essentially no unpleasant odors and/or health damaging emissions and which furthermore shows no signs of discoloration by aging for a lengthy time period, as well as a method for manufacturing the floor covering.
