Abstract:
A colored web material exhibiting viewing-angle dependent color and comprising a plurality of discrete extended elements. In one embodiment, the colored web material comprises a first web material and a second web material, wherein the first web material comprises a first polymer having first refractive properties and the second web material comprises a second polymer having second refractive properties, wherein said first refractive properties of said first polymer are different than said second refractive properties of said second polymer. In one embodiment, the colored web material comprises an interference pigment incorporated in at least one layer of the colored web material. In one embodiment, the discrete extended elements have a diameter of less than about 500 microns. In one embodiment, the colored web material comprises at least about 95 discrete extended elements per square centimeter. In one embodiment, the discrete extended elements have an aspect ratio of at least about 0.2.
