COMPOSITE COATING OF VARIABLE THICKNESS HAVING A GRADIENT COLORATION IN THE CROSS-WEB DIRECTION
摘要
Composite coatings are provided having a variable thickness and a gradient coloration in the cross-web direction using a premetered extrusion coating process wherein a pigmented coating composition and a non-pigmented coating composition are simultaneously extruded onto a carrier film. The composite coatings are useful in preparing laminated structures such as automobile windshields with a colored gradient band.
