Abstract
The invention provides multilayer surface coverings each having a layer obtained from a filler-containing PVC plastisol and obtained from a filler-free PVC plastisol, each of which comprises a plasticizer composition comprising bis(2-ethylhexyl) cyclohexane-1,4-dicarboxylate. Such surface coverings may be used as floor coverings or as imitation leather.
Claims22
A multilayer surface covering comprising at least one layer obtained from a filler-containing PVC plastisol comprising PVC, a filler and a plasticizer composition, and at least one layer obtained from a filler-free PVC plastisol comprising PVC and a plasticizer composition, wherein the plasticizer composition in the filler-containing PVC plastisol and in the filler-free PVC plastisol respectively contains bis(2-ethylhexyl) cyclohexane-1,4-dicarboxylate in a proportion of greater than 50% by weight based on the plasticizer composition.
A multilayer surface covering comprising:
- at least one layer obtained from a filler-containing PVC plastisol comprising PVC, a filler and a plasticizer composition, and
- at least one layer obtained from a filler-free PVC plastisol comprising PVC and a plasticizer composition,
- wherein the plasticizer composition in said filler-containing PVC plastisol and in said filler-free PVC plastisol respectively contains bis(2-ethylhexyl) cyclohexane-1,4-dicarboxylate in a proportion of greater than 50% by weight based on the plasticizer composition,
- wherein said at least one layer obtained from the filler-free PVC plastisol is an upper transparent layer of the multilayer surface and said at least one layer obtained from said filler-containing PVC plastisol is a lower layer of the multilayer surface.
