Claim 16:
17. A windshield comprising:
a first glass substrate,
a second glass substrate, and
an interlayer having improved gradient quality, comprising:
a first layer having a clear portion and a gradient color band portion, and wherein the gradient color band portion is encapsulated within the clear portion,
wherein the gradient color band portion has a cut-off X at the start of the gradient color band, a point Y where the % transmittance of the gradient color band is 40%, a point Z where the % transmittance of the gradient color band is 70%, a distance D that is the distance from X to Y and a distance d that is the distance from Y to Z,
and wherein the distance D in the gradient portion meets the following equations: 22.9 mm<D<38.1 mm and D/d<2.00,
wherein the interlayer is between the first glass substrate and the second glass substrate.
