摘要： A reflective article has a structured surface which includes a first and second array of reflective elements. The first array includes elements which have at least a first, second, and third reflecting face arranged to retroreflect incident light in a retroreflected beam. The second array includes elements which have at least a fourth, fifth, and sixth reflecting face arranged to reflect incident light in a second beam at an observation angle greater than 2 degrees. In signing applications, the second beam can be light originating from a stationary light source, the second beam having a direction and beam width suitable for illuminating an observation zone of interest. The retroreflected beam can be light originating from a moving light source such as a vehicle headlamp. Sheeting comprising such an article can be used both where external lighting from a suitable stationary light source is available and where it is not available.

摘要： An imaging element is disposed on a front surface of a retroreflective sheeting to form an image-displaying sheeting. The imaging element includes a light-transmitting prismatic sheeting that has a surface provided with a plurality of parallel prisms. The imaging element also includes an adhesive layer that adheres the prismatic sheeting to the front surface of the retroreflective sheeting. At least a portion of the imaging element is shaped in the form of indicia. In some cases the prismatic sheeting itself is shaped in the form of indicia. In other cases the imaging element includes a light-transmitting colored layer disposed on the front surface of the retroreflective sheeting and shaped in the form of indicia. In the latter case, the prismatic sheeting can be shaped as before to match the indicia-shaped colored layer, or it can extend continuously across the entire retroreflective sheeting. A stationary light source can be added and suitably positioned to enhance visibility of the image in a viewing plane.

摘要： A retroreflective article comprising a monolayer of microspheres partially embedded in and protruding from a binder layer and specular reflector underlying the microspheres, wherein the monolayer of microspheres comprises a mixture of a first class of microspheres having a first refractive index and a second class of microspheres having a second refractive index wherein the second refractive index is higher than the first refractive index. As a result, the sheeting exhibits superior observation angle angularity.
