Abstract

Novel, unstretched synthetic papers being virtually free of mechanically produced microvoids and having a porous surface for writing and printing thereon are disclosed. The unstretched synthetic papers of the instant invention are formed typically by extruding from pellets a film or sheet material formed with a continuous olefin resin matrix containing an effective amount of a particulate filler having microvoids inherent thereto, such as a diatamaceous earth. The microvoid particulate filler is dispersed somewhat uniformely yet randomly throughout the continuous olefin resin matrix of the unstretched synthetic papers to provide non-mechanically produced microvoids in with the surfaces porous for imparting writeability and printability thereto. The novel, unstretched synthetic papers of the present invention have good receptivity and retentivity for common writing materials, such as ink, pencil lead, and paint, even though they are not mechanically stretched to form mechanically produced microvoids .
