on the base film 11 the base film 11 provides a smooth surface upon which the prism elements can attach preferably to the window side of the prism elements the prism array 12 can be laminated to the base film 11 with a transparent adhesive or the prism array can be cast directly onto the base film using a polymer the prism array 12 polymer is selected from a variety of polymers which include the polymers of urethane acrylic acid esters cellulose esters ethylenically unsaturated nitrile hard epoxy acrylates and other polymers including polycarbonates polyesters and polyolefins acrylated silanes and hard polyester urethane acrylates the prism array 12 has a window side and facet sides and is attached on the window side to the base film 11 in this case the prismatic sheeting is produced on polyester film from 0 005 to 0 20 inches in thickness and the prism material is an acrylic cured resin the prisms 13 can be many sizes and type of corner cube from 0 001 to several inches on center and can have geometries that are tilted off axis and can even be different sizes of corner cubes on the same sheet the retroreflective structure 10 is then aluminum metalized 14 on the side of the prism array 12 and a top coat 15 or several top coats of clear or color coatings are applied for various purposes including colorization uv protection abrasion resistance wavelength selectivity or the like on the reverse side or top of the base film 11 this metalized retroreflective sheeting 10 can then be laminated as shown in fig2.
