Abstract
A shaped interlayer blank adapted for use with glass in a vehicle windshield, such blank formed of plasticized polyvinyl butyral and having a quadrilateral peripheral contour with two sides of arcuate shape and a wedge-shaped thickness profile. The blank preferably has an arcuate gradient color band substantially parallel to an arcuate edge of the blank in the greater thickness region of the blank. The wedge-shaped thickness gradually increases from about 30 mils to about 35 to 40 mils across the width of the blank. The blank is tailored for safety windshields featureing head-up displays where to function effectively the glass layes must be nonparallel and canted with respect to each other.
