摘要： The invention refers to a transparent pressure-sensitive adhesive layer

the pressure- sensitive adhesive of which comprises

(i) the reaction product obtainable by polymerizing a precursor comprising (a)one or more alkyl (meth)acrylate monomers the alkyl groups of which comprise independently from each other 4 to 20 carbon atoms, and
   (b)one or more moderately polar Lewis base-functional copolymerizable monomers, and
(ii) one or more tackifying resins

   wherein

the concentration of the alkyl acrylate monomer or monomers and the thickness of the pressure-sensitive adhesive layer are selected so that the pressure-sensitive adhesive layer has a 90° peel adhesion from polycarbonate after a dwell time of 72 as measured according to FINAT method no. 2 of at least 35 N/1.27 cm.
