A decorative film or sheet having a laminate structure comprising a surface layer, an adhesive layer, and a layer having a pattern or a laminate structure comprising a surface layer, an adhesive layer, a layer having a pattern, an adhesive layer, and a substrate, wherein the surface layer is made of a film of a sheet comprising a resin which comprises (A) 100 to 60% by weight of a substantial homopolymer of polypropylene having a pentad fraction, a peak temperature of melting, and an enthalpy of melting each in a specific range and (B) 0 to 40% by weight of a thermoplastic elastomer copolymer and a decorative building material having a surface layer made of a film or a sheet comprising the above resin. In accordance with the present invention, a laminated decorative film or sheet which comprises a surface layer having excellent transparency and hardness, has excellent workability in bending, V-cutting, lapping, and vacuum molding, and does not cause problems in disposal and a decorative building material which has excellent heat resistance, weatherability, and abrasion resistance, provides soft feeling, and does not cause problems in the environment can be obtained easily.
A decorative film or sheet having a laminate structure comprising a surface layer, an adhesive layer, and a layer having a pattern, wherein the surface layer is made of a film or a sheet comprising a resin which comprises (A) 100 to 60% by weight of a polypropylene resin comprising one or both of a homopolymer of propylene and a copolymer of propylene containing 4% by weight or less of units of other olefins, the homopolymer and the copolymer having (i) a pentad fraction expressed by rrrr/(1−mmmm)×100 of 15 to 60% as measured by a nuclear magnetic resonance spectrum of an isotopic carbon (13C-NMR), (ii) a peak temperature of melting (Tm) of 150° C. or higher as measured by a differential scanning calorimeter (DSC), and (iii) an enthalpy of melting (ΔH) of 100 J/g or less as measured by DSC, and (B) 0 to 40% by weight of a thermoplastic elastomer copolymer.
