Zusammenfassung:	PURPOSE:To obtain a sheet, having natural appearance as well as shade near to a high-class leather and provided with soft and warm properties, by a method wherein a polyurethane elastomer film layer, consisting of 1-2 layers, is laminated on a thermoplastic resin layer, consisting of two layers including a foamed layer, through an adhesive agent layer. CONSTITUTION:The title sheet is constituted of a transparent or semitransparent colored polyurethane elastomer film layer 1, a colored polyurethane elastomer film layer 2, a polyurethane adhesive agent layer 3, a thermoplastic resin layer 4 and a thermoplastic resin formed layer 5. The sheet is manufactured by a method wherein a composite for the transparent colored layer 1 is applied and dried on release paper with crest patterns at first, subsequently, a composition for the colored layer 2 is applied and dried on the composition for the colored layer 1, further, two-pack mixed composition for the adhesive agent layer 3 is applied and dried thereon to form layers 1-3. In another process, plastic sol for a foaming layer 5 is applied on the release paper to heat and expand it, then, a composite for a sheet layer 4 is applied thereon to heat and cause to gel and form two layers 4, 5. Subsequently, the coating layers formed on the release papers respectively are integrated by bonding through the adhesive agent layer 3.
