Abstract[English]
Microcapsules including a color-filtering shell and a core comprising a leuco dye or dye precursor, a photoinitiator or photosensitizer, and a photohardenable or photosoftenable material are provided for use in microcapsule imaging sheets. The imaging sheets including such microcapsules reduce undesirable crosstalk among the microcapsules of various colors and provide significantly improved color fidelity of the image thus reproduced.[French]
L'invention concerne des microcapsules comprenant une enveloppe de filtration de couleur et un noyau comprenant un leuco-colorant ou un précurseur de colorant, un photoamorceur ou un photosensibilisateur, et un matériau photodurcissable ou photoramollissable destiné à être utilisé dans des feuilles d'imagerie de microcapsule. Les feuilles d'imagerie comprenant de telles microcapsules réduisent une diaphonie indésirable parmi les microcapsules de diverses couleurs et fournissent une fidélité de couleur significativement améliorée de l'image ainsi reproduite.
