Beschreibung
Zusammenfassung:	A multi-layer sheet material includes at least one textile substrate layer, at least one foamed layer made of polyvinyl chloride containing plasticizer, at least one cover layer made of polyvinyl chloride containing plasticizer, and at least one coating layer facing outward on the cover layer. The invention further relates to a method for producing the multi-layer sheet material and to an interior trim part made of a sheet material for a vehicle. For a reduced tendency to yellow under high-temperature aging and for greater color fastness, the polyvinyl chloride fraction in the cover layer is based at least 50 wt% on a polyvinyl chloride that was produced according to the method of suspension polymerization (S-PVC), and the composition for the cover layer comprises a calcium hydroxide stabilizer and/or a Ca/Zn stabilizer that contains 1 to 3 wt% calcium and 1 to 2 wt% zinc.
