Title
(EN) DUAL-LAYER SELF-CONTAINED RECORDING PAPER INCORPORATING HOLLOW MICROSPHERES
(FR) PAPIER SC A DOUBLE EPAISSEUR RENFERMANT DES PIGMENTS PLASTIQUES SPHERIQUES CREUX
Abstract
(EN)
A self-contained sheet for forming an image comprising a support, a first layer of microcapsules containing a color precursor of the electron donating type in a carrier liquid on the surface of the support, a layer of microspheres overlying the microcapsule layer, and a developer material present in at least one of the microcapsule layer or microsphere layer, wherein the developer material can react with the color precursor to form a visible image when the color precursor is released from the mircrocapsules.
(FR)
L'invention concerne une feuille SC destinée à la formation d'une image, comprenant un support, une première couche de microcapsules renfermant un précurseur de couleur du type donneur d'électrons dans un liquide de support, sur la surface du support, une couche de microsphères recouvrant la couche de microcapsules, et une matière de développement présente dans au moins une des deux couches. Cette matière de développement peut réagir avec le précurseur de couleur afin de former une image visible lorsque le précurseur de couleur est libéré des microcapsules.
