Abstract
A polyurethane top coating and a porous, polyurethane interposing layer are formed on a release carrier sheet. Split leather hide is bonded onto the porous layer with a compatible adhesive and the release carrier sheet is stripped from the top coat. The resultant laminate has the appearance and other properties of top-grain leather. The interposing porous layer functions as a cushion and prevents uneven deformation of top coat when the laminate is folded or stretched.
