Abstract

A pressure sensitive adhesive layer with a structured surface, wherein the adhesive layer is capable of being dry laminated to a substrate to form a laminate. The adhesive layer has a haze after lamination, measured according to ASTM D 1003-95, of less than about 50% of the haze of the adhesive layer before lamination. After dry lamination, the adhesive layer has a luminous transmittance of more than about 85%, a haze of less than about 25%, and an opacity of less than about 3%.
