Abstract
This invention relates to a light transmitting filter comprising (a) light absorbing layer having a first and second surface, (b) microspheres embedded in the light absorbing layer and (c) an optically clear, substantially uniform, conformable layer covering the microspheres, wherein the microspheres provide light tunnels through the light absorbing layer. The invention also relates to methods of making the same. The invention also relates to a method of preparing a light transmitting filter comprising the step of laminating a clear substantially uniform conformable layer over transparent microspheres embedded in a light absorbing layer wherein the transparent bead form light tunnels through the light absorbing layer. The light transmitting filters of the present invention have improved light throughput and improved angularity.
