Summary:A decorative film according to the present disclosure comprises a laminate comprising a hard coat layer and a base material layer. The hard coat layer consists of a cured product of a thermosetting coating material comprising an acrylic copolymer (A) having hydroxy groups and an isocyanate curing agent (B). The hard coat layer has a predetermined total light transmittance, diffuse transmittance and tensile strength. The acrylic copolymer (A) has a specific hydroxy value, acid value, glass transition temperature, Mw and Mw/Mn and is a copolymer having units derived from monomers having hydroxy group(s). The content percentage of a unit derived from a monomer having one hydroxy group in 100% by mol of the units derived from monomers having hydroxy group(s) and the content percentage of a primary hydroxy group in the acrylic copolymer (A) satisfy specific ranges.
