Abstract
The invention relates to multi-layer composites for use as a screen, having at least three layers, with an inner diffusing layer and at least one substrate layer on either side. The diffusing layer contains small particles having a narrow particle size distribution that are refractive-index mismatched with the polymer matrix. The multi-layer acrylic composition is useful as a projection screen.
