Claim:
1. A method for producing a molded body, the method comprising: providing a composite, the composite including a first plate having a polymer film pressed into a surface of the first plate; providing a third plate, the third plate including roughened areas on at least parts of one or more surfaces thereof, the roughened areas having a mean roughness R placing the third plate opposite the pressed-in polymer film without the third plate touching the composite; then heating the third plate to a temperature above the glass transition temperature T structuring the surface of the pressed-in polymer film facing the third plate by a relative movement which removes the third plate from the first plate while the pressed-in polymer film remains soft and is thus extended lengthwise, thereby forming a modified composite that comprises the molded body.
