Abstract

Laminated automotive glazing including plastic layers and glass having an obscuration area produced by printing on the plastic layers of the laminate rather than printing and firing a black enamel frit onto the glass. This results in an obscuration having superior optical quality, higher strength and a lower probability of breakage as compared to a black enamel frit obscuration.

First claim

The invention claimed is:

1. A laminated windshield comprising:
at least two glass layers;
at least two plastic layers sandwiched between the at least two glass layers, the at least two plastic layers attaching said at least two glass layers to each other;
at least one obscuration produced by inkjet printing said obscuration onto two surfaces of the at least two plastic layers to produce a three dimensional appearance;
a UV blocking plastic layer sandwiched between the at least two glass layers; and
a color correction filter printed directly onto at least one of the at least two plastic layers;
wherein the laminated windshield has improved fracture strength, reduced distortion and reduced double image.

2. The laminated windshield of claim 1 further comprising an equipment obscuration printed onto at least one of the at least two plastic layers.

3. The laminated windshield of claim 1 further comprising a black band obscuration printed onto at least one of the at least two plastic layers.

4. The laminated windshield of claim 3 further comprising an equipment obscuration separate from and spaced from the black band obscuration.

5. The laminated windshield of claim 1 further comprising a wiper rest obscuration printed onto at least one of the at least two plastic layers.

6. The laminated windshield of claim 1 further comprising at least one performance film plastic layer.

7. The laminated windshield of claim 1 , wherein the obscuration is printed on two parallel surfaces of the at least two plastic layers.

8. The laminated windshield of claim 1 , wherein at least one performance film plastic layer is sandwiched between the at least two plastic layers.

9. The laminated windshield according to claim 1 , wherein the improved fracture strength is about 115 Mpa, the reduced distortion is 25 milli diopters, and the reduced double image is 3″ arc minute.
