There is provided an article comprising at least a first surface having: (a) a first binder layer; (b) a plurality of transparent microspheres at least partially embedded in the first binder layer; wherein the transparent microspheres have refractive indices that are less than a refractive index of the first binder layer, wherein the plurality of transparent microspheres have an average diameter of at least 5 μm. There is also provided a transfer article comprising: (a) a transfer carrier, the transfer carrier comprising: (i) a support layer; and (ii) a thermoplastic release layer bonded to the support layer; (b) a layer of a plurality of transparent microspheres, formed on a side of the thermoplastic transparent microsphere release layer opposite the support layer, wherein the plurality of transparent microspheres have refractive indices of below about 1.490. |
