Adhesive film for tinting automotive lenses and method

A tint wrap for an automotive lens comprising:

• a tint film for wrapping the automotive lens for tinting thereof, the tint film defining opposite outer and inner faces and being bounded by peripheral edges defining a surface area therebetween, the inner surface comprising a dry applied adhesive material for being adhesively mounted to the automotive lens;
• and
• a back liner supporting the tint film thereon, the back liner comprising an outer rear surface and an opposite inner support surface defining an embossed pattern formation thereon of peaks and valleys, the tint film overlaying the back liner with the inner face of the film engaging the support surface, the formation forming a corresponding pattern formation in the adhesive extending the surface area of the film between the peripheral edges and defining contiguous air channels with flat areas interposed therebetween, the air channels being connected at intersections about the flat areas, each air channel defining a top wall, a bottom opening defining a plane thereof and spaced apart lateral walls therebetween, the top wall and the bottom opening defining an air channel height therebetween, the spaced apart lateral walls defining an air channel width therebetween, wherein the air channel width is greater than the air channel height anywhere along the air channel height,
• wherein when the tint film being removed from the back liner and being mounted to the automotive lens for wrapping thereof, the air channels provide for air between the tint film and the automotive lens to be released via the peripheral edges and wherein the air channels collapse for providing the top wall of the air channels to engage the automotive lens.
