Laminated adhesive backed color correction and light-diffusion filters

A laminated adhesive backed color-correction and/or light-diffusion filter comprising:

• a) a gel layer having a predetermined thickness, width and color so as to provide desired color and/or light wavelength characteristics when filter is applied to light source;
• b) an optically transparent substrate support layer of a width at least equal to that of said gel layer, the substrate support layer having a top face and a bottom face, an optically transparent peelable protective film layer, the substrate support layer being disposed between the gel layer and the protective film layer;
• c) a first optically transparent adhesive layer disposed between the gel layer and the transparent substrate layer and serving to bind the gel layer to the top face of the transparent substrate support layer;
• d) a second optically transparent adhesive layer between the protective film layer and the bottom face of the substrate support layer and serving to bind the bottom face of the substrate layer to the protective film layer so that when the filter is to be attached to a surface the protective film layer can be removed to expose the second optically transparent adhesive layer and such layer can be employed to anchor the filter to such surface;
• e) wherein the optically transparent peelable protective film layer is scored so that a portion thereof can be removed to facilitate positioning of the filter before the remaining portion of the optically transparent protective film layer is removed;
• f) wherein a seam is scored along the entire length of of the optically transparent peelable protective film layer;
• g) wherein said peelable optically transparent protective film layer can be removed from said optically transparent adhesive layer such that the adhesive quality of said layer be exposed so as to position the filter wherever user may need it.
