摘要: MULTIPLE LAYER FILMS ARE MADE BY ARRANGING A MINIMUM OF TWO STREAMS INTO ONE STREAM HAVING A PLURALITY OF GENERALLY PARALLEL LAYERS. BY MECHANICALLY MANIPULATING THE LAYERED STREAM AN INCREASED NUMBER OF LAYERS ARE OBTAINED AND THE MANIUPLATING STREAM IS SHAPED INTO A DESIRED CONFIGURATION HAVING A PLURALITY OF LAYERS GENERALLY ADJACENT TO A MAJOR SURFACE THEREOF. UNDER CERTAIN CONDKTIONS, IRIDESCENT PRODUCTS ARE OBTAINED WITHOUT THE USE OF PIGMENT.

摘要: Layered sheet having selectively foamable layers is prepared employing a laminate of at least three layers of synthetic resinous materials, the outer layers are relatively permeable to a blowing agent and a central layer is relatively impermeable to a blowing agent. The laminated sheet is impregnated with a fluid (either liquid or gaseous blowing agent), the sheet exposed to conditions which permit loss of the blowing agent from the outer layers and subsequently heated to foam an inner or central layer.
