Abstract: Embodiments relate to a decorative sheet having a hairline design and including successively, from a front surface side thereof, (A) a layer of a transparent resin film and (B) a layer of an ink paint film containing high brightness pigment. A plurality of linear hairline grooves is provided on a surface of the transparent resin film on a side thereof facing (B) the layer of the ink paint film containing the high brightness pigment. The decorative sheet has a surface resistivity of 1×105Ω or more on a rear surface side thereof. When the decorative sheet is placed on a dirt comparison chart created by the NPB in an environment of an illuminance of 600 lux, and is illuminated from below the chart at an illuminance of 17000 lux, a figure having a size of 5 mm2 on the chart can be visually discriminated. When the decorative sheet is placed on a gray scale for soiling stipulated in JIS L0805:2005 in an environment of an illuminance of 500 lux, the color difference between color chips numbers 4 and 5 cannot be visually discriminated.

Abstract: Embodiments of the invention provide a transparent poly(meth)acrylimide-based resin multilayer film exhibiting excellent surface smoothness, transparency, outer appearance, and resistance to puchability. According to at least one embodiment, there is provided a method for producing said transparent multilayer film, in which the transparent multilayer film in which a first poly(meth)acrylimide-based resin layer (α1), an aromatic polycarbonate-based resin layer (β), and a second poly(meth)acrylimide-based resin layer (α2) are directly laminated in said order, and in that the total light transmittance exceeds 90% and the haze is 2.0% or lower. The transparent multilayer film is produced by continuously coextruding, from a T die, a molten film of the transparent multilayer film in which the aforementioned layers were directly laminated in the aforementioned order, and by supplying and then pressing the molten film between a first mirror body that has a surface temperature between 100 and 200° C. and a second mirror body that has a surface temperature between 20 and 200° C.
