摘要:
A method of making a retroreflective marking material is provided, the method has the steps of: (a) providing an enclosed-lens retroreflective sheet having a top surface and a bottom surface and comprising a cover layer and a monolayer of retroreflective elements; (b) applying a conformance layer to the bottom surface of the retroreflective sheet; and (c) laminating a configuration member to the conformance layer thereby creating first portions and second portions in the sheet, the first portions being arranged in an upwardly contoured profile and the second portions being arranged in a lower, substantially planar position. A retroreflective article made by the method is also provided.
摘要:
Retroreflective pavement marking material comprising on the top surface thereof an enclosed-lens retroreflective sheet that comprises a monolayer of retroreflective elements wherein first portions of the monolayer are arranged in an upwardly contoured profile and second portions of the monolayer are arranged a lower, substantially planar position.
摘要:
A retroreflective article that exhibits suitable retroreflective luminance under dry and dynamic wet conditions. The article includes an enclosed-lens retroreflective sheeting that, under dry conditions, exhibits a coefficient of retroreflective luminance of about 40 (millicandela/m2)/lux as measured by ASTM D 4061-94 and, under dynamic wet conditions the sheeting increases in coefficient of retroreflective luminance. The article further includes a plurality of retroreflective elements partially embedded in a light transmissible bonding layer on the front, reflective surface of the retroreflective sheeting.

摘要:
A transparent cover film better protects enclosed-lens retroreflective sheeting and can be applied more economically when it is extruded and is a thermoplastic polymer which has good elongation and minimal elastic memory. Preferred polymers are (a) aliphatic urethanes and (b) copolymers of ethylene or propylene.

摘要:
A pavement marking tape having a scrim, wherein the scrim is extensible to enable the tape to conform to irregularities in a road surface, and thereby bond more securely to that surface.
