Abstract[English]
Imaging systems, microcapsules and method are provided, including an under-layer including one or more pressure-sensitive microcapsules including a solvent, plasticizer, or a diluent and/or a photo-hardenable black microcapsule including a black leuco-dye or a leuco-dye system. The resulting imaging sheets achieve improved image color saturation, an improved rate of image development, and enhanced dye mixing.[French]
L'invention concerne des systèmes d'imagerie, des microcapsules et un procédé, y compris une sous-couche comprenant une ou plusieurs microcapsules sensibles à la pression comprenant un solvant, un plastifiant ou un diluant et/ou une microcapsule noire photodurcissable comprenant un leuco-colorant noir ou un système de leuco-colorants. Les feuilles d'imagerie résultantes font preuve d'une saturation de couleurs d'image améliorée, d'une vitesse de développement d'image améliorée et d'un mélange de colorants amélioré.
