Abstract
Abstract An image-receiving sheet element comprising an image-receiving layer provided on a flexible substrate and a removable cover sheet, wherein said cover sheet comprises a low density copolymer containing 30% by weight or more of a linear polyethylene, is described. This image-receiving sheet element shows improved slip properties and a good workability, and little deterioration in transfer properties upon prolonged storage. Furthermore, it scarcely suffers from any caused by static electricity when the cover sheet is peeled off from the image-receiving sheet.
