Abstract

The present invention is in the field of laminated glass panels comprising multiple layers of polymer sheets with patterned light transmission qualities and methods of producing and using the same. More specifically, the present invention is in the field of laminated glass panels featuring novel patterns formed by two printed patterns supported on one or more layers of polymeric sheet material, such as polyethylene terephthalate.
