摘要： The invention relates to a pressure-sensitive surface-protecting film, especially for automotive paints, comprising a carrier layer and a pressure-sensitive layer on the basis of a cross-linked polyurethane. The inventive film is characterized in that the angle of loss tan δ of the polyurethane increases at room temperature in a frequency interval of from 10?-1 to 102¿ rad/sec or remains on the same level.
