Composite film structures exhibit a predetermined finished color tone comprised of a transparent film layer which exhibits a color deficiency as compared to the finished color tone, and a pigment which is visually associated with, and satisfies the color deficiency of, the film layer. Most preferably, the pigment is provided as a homogenous dispersion in a transparent color-matching layer positioned adjacent to the film layer. Thus, when the film and color-matching layers are viewed collectively as a unit, the perceived color tone will be that of the finished predetermined color tone. That is, the color-matching layer provides visually an additive effect on the perceived color of the composite film structure.

Light-stable colored transparent composite films

An optically active film composite comprising a transparent substrate and at least one layer of a block copolymer blend comprising between 30:70 to 70:30 percent by volume of each component of the copolymer, the block copolymer forming lamellar microdomains of each polymeric component, which components have different refractive indices. The thickness of the lamellae may be controlled through selection of molecular weights of the components and by the addition of compatible homopolymers.
