ABSTRACT:
An automotive transparency includes a first glass ply having a constant thickness, a second glass ply having a constant thickness, and an interlayer having a constant thickness in a first predetermined area and a decreasing thickness in a second predetermined area. The first and second plies are secured together by the interlayer to form a laminate having a first outer major surface, an opposing second outer major surface, a first predetermined area defined by the first predetermined area of the interlayer over which the outer major surfaces are substantially parallel to one another, and a second predetermined area defined by the second predetermined area of the interlayer over which the outer major surfaces are nonparallel to each other such that images reflected off the nonparallel surfaces of the laminate are substantially superimposed over each other to at least reduce double imaging of the reflected image.
