Abstract: The invention is directed to a photovoltaic roadway assembly, to the use of a primer layer comprising thermally reversible crosslinks, to a method of assembling a photovoltaic roadway assembly, and to a method of replacing at least part of a top layer in a photovoltaic roadway. The photovoltaic roadway assembly of the invention comprises a support, one or more photovoltaic modules assembled to said support, and a top layer, said top layer being attached to said one or more photovoltaic modules with a primer layer, wherein said primer layer comprises at least one organic polymer with thermally reversible crosslinks.

Abstract: The invention is directed to copy protected paper, to a method for producing said paper, the use of a specific layer for copy protection of paper, and a method for protecting a printable paper from being copied. Copy protected paper comprising a printable paper having, on a side to be printed or a printed side, a first transparent layer, wherein said first transparent layer has a difference in refractive index with i) said paper; or ii) an optional second transparent layer being provided on said paper on the side to be printed or the printed side, wherein said difference in refractive index is at least 0.05.
