this invention provides a thermoplastic multilayer resinous film in which two or more resinous materials form a plurality of very thin layers of substantially uniform thickness , the layers being substantially parallel , the contiguous adjacent layers being of different transparent thermoplastic resinous materials differing in refractive index , each of the outermost skin layers being at least 5 % of the total thickness of the film and the multilayer film containing a sufficient quantity of a pearlescent pigment in at least one of the interior layers to render it non - glossy .
