The sheet comprises a ply of high surfacearea polyolefin fibers masking a colored medium therein. The ply of polyolefin fiberswhen subjected to the localized pressure of a writing instrument becomes relativelytransparent in the region where the pressure is applied, to make distinct the coloredmedium distributed in the recording sheet.
