Abstract: A paper-containing laminate is disclosed which comprises:(a) an outer layer of opaque biaxially oriented polymer film structure of lustrous satin appearance which comprises:(i) a thermoplastic polymer matrix core having an upper surface and a lower surface and within which is located a strata of voids; positioned at least substantially within at least a substantial number of voids is at least one spherical void-initiating particle which is phase distinct and incompatible with the matrix material, the void space occupied by said particle being substantially less than the volume of said void, with one generally cross-sectional dimension of said particle at least approximating a corresponding cross-sectional dimension of said void;(ii) a void-free thermoplastic skin layer adhering to at least the upper surface of said core layer, said skin layer being of a thickness such that the outer, exposed surface thereof does not, at least substantially, manifest the surface irregularities of said core layer; the populatio

Abstract: Shapeforming acrylonitrile polymer film by providing acrylonitrile polymer aquagel film, conforming said aquagel film into the desired shape and while in said shape, heat-removing at least substantially all of the water from said aquagel film.
