Abstract
A flexible decorative web that can be laminated to a substrate and that exhibits serial changes in its appearance with changes in viewing angle relative to incident white light. Chromatic, iridescent and metallic pigments produce three separate appearance zones where the chromatic pigment is most predominant, where the iridescent pigment is most predominant and where a transition occurs and neither the chromatic pigment nor the iridescent pigment predominates. The metallic pigment accentuates the iridescent appearance or flash by its sparkle effect produced both in the iridescent appearance areas and in the transition areas immediately surrounding and highlighting the iridescent appearance areas.
