ABSTRACT:
A retroreflective structure is described in which an array of transparent prisms is formed on a release coating of a sheet. The facet side of the prisms is made reflective and the prisms are either released to form a plurality of individual retroreflective structures or the array is adhered to a supporting substrate and then released from the base sheet. In the latter case, the array can be applied to a pre-existing structure formed of compatible fabrics, such as tarpaulins.
