Abstract
The object of this invention is to provide a laminated automotive glazing having an obscuration area produced by printing the obscuration on a film laminated between at least two layers of plastic interlayers or directly on the interlayer rather than printing and firing an enamel frit onto the glass. This results in a laminate having superior optical quality, higher strength and a lower probability of breakage as compared to a laminate with a black enamel frit obscuration.
Claims8
An automotive laminated windshield, wherein at least one portion of the windshield serves as a window for at least one camera, said windshield comprises:
- two glass layers;
- two plastic interlayers, first and second plastic interlayers, disposed between said two glass layers and serving to bond glass layers to each other;
- at least one obscuration for said at least one portion of the windshield serving as a camera window;
- and
- a black enamel frit band separated from and spaced from said at least one obscuration;
- wherein said at least one obscuration is printed onto said second plastic interlayer which is cut to size the at least one portion of the windshield serving as a camera window, such that at least one machine vision parameter selected from the group consisting of fracture strength, distortion and MFTis improved in said at least one portion of the windshield serving as a camera window.
