Claims12
A paper member having a first surface area having a general surface roughness that produces distortion of a film optical element bonded thereon, and a second surface area contiguous with the first surface area and having a surface profile that will not distort a film optical element bonded thereon;
- and a film optical element bonded to at least a portion of said second surface area.
A paper member having a first surface area having a general surface roughness that produces distortion of an embossed optical element bonded thereon, and a second surface area contiguous with said first surface area and having a surface profile that will not distort an embossed optical element bonded thereon;
- an adhesive layer on at least a portion of the second surface area;
- and an embossed optical element applied to the adhesive layer.
