A pressure sensitive adhesive tape comprises a carrier layer having a thickness of 0.25 to 2.0 millimeter and comprising an electron beam cured pressure sensitive adhesive matrix, 10 to 20% by volume low density microspheres and at least one pigment in an amount sufficient to color the tape. Preferably, fumed silica is present in an amount up to 5% by weight. The tape preferably has a kin layer on each side of the carrier layer. The skin layer has a coating thickness of 25 to 125 g/m.sup.2 and comprises a pressure sensitive adhesive matrix free of rigid, low density microspheres. The process comprises first preparing an adhesive composition containing electron beam-curable adhesive polymer matrix, fillers and solvent. The composition is introduced and conveyed through a twin screw extruder. In the extruder, solvent is removed in one or more solvent removal units, and a solvent-free composition is extruded as the carried layer. Skin layers may be co-extruded with the carrier layer.

An adhesive laminate, including a base web having a coating of pressure-sensitive adhesive and a backing removably adhered to the coating of adhesive for protecting and containing the adhesive, is described. The backing has one or more non-linear, discontinuous score lines formed, preferably, with a laser. A sine-wave, geometric pattern is also preferred. The non-linear, discontinuous score line enables a crack-and-peel feature to be introduced to the laminate backing.

Apparatus and methods for measuring retroreflective properties of a surface are disclosed. The apparatus and methods are characterized in that the measured angle of divergence is varied while the angle of incidence is simultaneously varied.
