Black enamel frit obscurations are commonly printed on laminated and tempered automotive safety glazing where they serve to hide the adhesive used to bind the glazing to the automotive body and to protect the adhesive from ultraviolet radiation. However, frit has a number of drawbacks. Frit weakens the surface of the glass. It can create distortion in the glass due to thermal gradients. Printed frit obscurations are incompatible and cannot be used with many types of coatings. Standard frit blocks ion exchange and cannot be used with the chemical tempering process. In addition, while many types of frits are available for printing on soda-lime glass, there are very few, if any, for non-soda lime glass. As the market moves towards thinner and lighter glazing, non-soda lime glass types are finding increasing application in automotive glazing. These limitations are overcome by replacing the printed black obscuration with an obscuration formed from a thin sheet of plastic, which is integrated into the laminate. 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.

The laminated glass panoramic roof is a popular although expensive option offered on a growing number of automobiles. Much of its appeal comes from the sleek modern appearance that it gives to the vehicle. The opaque laminated vehicle roof, by removing vision and optical requirements can be produced at a lower cost. The opaque laminated roof, by retaining a glass outer surface, maintains the same exterior appearance, aesthetic and much of the appeal of a conventional laminated glass panoramic roof. The opaque laminated vehicle roof also allows for the use of alternate materials which can further reduce cost and weight while adding additional features such as installation hardware, fasteners, lighting, antennas and solar cells to the roof.

The use of camera-based safety systems is growing at a rapid rate in modern automobiles. At the same time, windshields, where many of the cameras are mounted, are becoming larger and more complex in shape. As the industry moves towards vehicles with full autonomous capability, the number of cameras required and the resolution of the cameras are both increasing. However, the optical quality of the windshield is less than optimal. One of the problems is caused by the typical black enamel frit that is printed on the glass, prior to heating and bending, to hide or obscure the camera hardware. The abrupt thermal gradients during bending, caused by the heat absorbing black frit, result in a high level of distortion in the camera field of view. The object of this invention is to provide laminated automotive glazing having an obscuration area produced by creating an obscuration after heating and bending the glass by removing a portion of the plastic interlayer glass in or near the camera field of view (camera obscuration) or/and in the edges of the windshield (black band) and replacing it with an inlay made of a substantially opaque plastic or other suitable material in or near the camera field of view (camera obscuration) or/and in the edges of the windshield (black band) rather than printing and firing an enamel frit on 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.
