Abstract (en)

A self-contained color forming pressure sensitive record paper of the single coating type which has on one side of a support a coating layer of a mixture of color former-containing microcapsules and color developer-containing microcapsules, as well as a powdered polyolefin. The powdered polyolefin acts as capsule protecting agent and prevents the smudging due to unintentional color development caused by the rapture of the capsules.
