Light-stable colored transparent composite films
First Claim
1. A composite transparent structure comprising a glass substrate, and a transparent film transparent film which exhibits a predetermined finished color tone, wherein said transparent film comprises:
- 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
at least one pigment having an average particle size of less than about 0.50 μ
m which is visually associated with the film layer 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 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.

10. A process for making a composite transparent structure comprised of a glass substrate and a transparent film which exhibits a predetermined finished color tone, said process 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;
(b) visually associating with said film layer 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 transparent film the predetermined finished color tone when the color-deficient dyed film layer and the at least one pigment are viewed collectively as a unit; and
(c) adhering the transparent film to a glass substrate to form said composite transparent structure. - View Dependent Claims (11, 12, 13)
