Abstract (en)
[origin: EP0120972A1] A self color-forming pressure-sensitive sheet having on its surface a single recording layer containing color former-incorporating microcapsules and color developer-incorporating microcapsules as necessary components, with the recording layer containing a waxy material such as higher fatty acid, its water-insoluble metal salt or amide, can remarkably prevent undesirable color formation due to folding of paper sheets without reducing necessary printing color density.
