  • Patent number: 3953642
    Abstract: A pressure sensitive recording sheet adapted for imaging under the pressure of a typewriter key or other writing instrument. The sheet comprises a ply of high surface area polyolefin fibers masking a colored medium therein. The ply of polyolefin fibers when subjected to the localized pressure of a writing instrument becomes relatively transparent in the region where the pressure is applied, to make distinct the colored medium distributed in the recording sheet.
