ABSTRACT:
A multilayer coextruded slat having upper and lower surfaces has an opaque base layer containing a first thermoplastic polymer, and a thin transparent pearlescent layer containing a a second thermoplastic polymer upon at least one surface of the opaque base layer. In an alternate embodiment a center layer is confined between the opaque base layer and the clear transparent pearlescent surface layer to provide a pearlescent color effect. Such multilayer coextruded slats may be utilized as the louvers for a vertical blind. In an alternate utility the coextruded multilayer slat may be utilized as the color insert for a vertical blind louver which has longitudinally grooved transparent side edges which are adapted to hold a color insert.
