Light-stable colored transparent composite films
First Claim
1. A transparent film which exhibits a predetermined finished color tone comprising:
- a color-deficient dyed transparent film layer which exhibits a color deficiency in at least one of hue, chroma and value as compared to the predetermined finished color tone; and
a transparent color-matching layer visually associated with said film layer, said color-matching layer including at least one pigment having an average particle size of less than about 0.50 μ
m and exhibits a matching color tone satisfying the color deficiency of said film layer to thereby impart to the transparent film the predetermined finished color tone when the color-deficient dyed film layer and the color-matching layer are viewed collectively as a unit.

Abstract
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.

24. A process for making a transparent composite film which exhibits a predetermined finished color tone comprising the steps of:
-
(a) providing a color-deficient dyed transparent film layer which exhibits a color deficiency in at least one of hue, chroma and value as compared to the predetermined finished color tone; and
(b) visually associating at least one color matching layer with said film layer, wherein said at least one color matching layer includes at least one pigment having an average particle size of less than about 0.50 μ
m and exhibiting a matching color tone satisfying the color deficiency of said film layer to thereby impart to the composite film the predetermined finished color tone when the color-deficient dyed film layer and color-matching layer are viewed collectively as a unit.- View Dependent Claims (25, 26, 27, 28, 29)
