Zusammenfassung:PROBLEM TO BE SOLVED: To produce a sheet excellent in productivity and rear surface adhesiveness without generating material loss and refuse. SOLUTION: A sheet 1 excellent in rear surface adhesiveness is constituted by laminating a sponge layer comprising a foamable vinyl chloride resin compsn. and a finely foamed rear surface layer comprising a vinyl chloride resin compsn. in which microcapsules of which the shell walls comprise a thermoplastic synthetic resin are uniformly dispersed and the rear surface 2 of the sheet has projections formed by microcapsules expanded when the vinyl chloride resin compsn. is gelled under heating and/or recesses formed by the destruction of expanded microcapsules.
