Light-stable colored transparent composite films

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 having an average particle size of less than about 0.50 μm which exhibits a matching color tone satisfying the color tone deficiency of said film layer.

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 μm 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.

A transparent composite film which exhibits a predetermined finished color comprising a transparent film layer which exhibits a yellow color deficiency, and a color-matching layer adjacent said transparent film layer, wherein said color-matching layer includes yellow-colored pigment particles having an average particle size of less than about 0.50 μm in an amount sufficient to visually satisfy the yellow color deficiency of said film layer such that said film and color-matching layers collectively exhibit the predetermined finished color when viewed together as a unit.

The combination comprised of a glass substrate, and affixed thereto, a 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 μm which is visually associated with the film layer, wherein said at least one pigment 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.
