Light-stable colored transparent composite films
First Claim
1. A transparent film which exhibits a predetermined finished color tone comprising:
- a 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
at least one pigment visually associated with the film layer 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 film and at least one pigment 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.

16. A transparent composite film having a finished gray color tone comprising:
-
a transparent polyester terephthalate film layer which is dyed to exhibit a selected color tone having a color deficiency in at least one of red, blue and yellow color tones as compared to the finished gray color tone of the composite film; and
a transparent color-matching layer adjacent said film layer containing a pigment which exhibits a matching color tone satisfying the color tone deficiency of said film layer. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A process for making a transparent film which exhibits a predetermined finished color tone comprising the steps of:
-
(a) providing a 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 with said film layer at least one pigment exhibiting a matching color tone satisfying the color deficiency of said film layer and thereby imparting to the composite film the predetermined finished color tone when the film and color-matching layers are viewed collectively as a unit. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
