Patent ID: 8182903

Claim:
A decorative thermoplastic structure formed to have the appearance of a unitary color throughout its composition, the structure comprising: a substantially translucent thermoplastic resin substrate having opposing front and back surfaces, wherein the front or back surface comprises a bonding surface having a first surface roughness; a first thermoplastic colored film layer that has a bonding surface with a second surface roughness that is different from the first surface roughness, wherein the bonding surface of the first colored film layer has been fused to and intermixed with the bonding surface of the resin substrate; and a second thermoplastic colored film layer fused to at least one of the first colored film layer and the resin substrate, such that the resin substrate is fused to one or both of the first or second colored films; wherein: the surface roughness of at least one of the bonding surfaces of the resin substrate or the first colored film comprises an even distribution of texture granules; the fused first and second colored film layers -impart a third color throughout the entire thermoplastic structure, such that the color of the thermoplastic structure remains the same throughout the thermoplastic structure regardless of the viewing direction; and the resin substrate is thicker than the one or both of the first or second colored film layers.
