Abstract[English]
Imaging systems, apparatus, developer systems and methods are provided which includes a two-layer developer comprising a low-haze clear developer layer (De) and a microporous translucent developer layer (Dp). The microporous translucent developer layer is deposited between an imaging layer which includes photosensitive microcapsule layer and the low-haze clear developer layer. The resulting imaging sheets achieve improved image color saturation, an improved rate of image development and enhanced dye mixing, and an improved printing energy efficiency as well as an improved weatherability or discoloration resistance of the developed image.[French]
L'invention concerne des systèmes d'imagerie, un appareil, des systèmes de révélateur et des procédés qui comprennent un révélateur double couches comprenant une couche de révélateur transparent à faible trouble (De) et une couche de révélateur translucide microporeuse (Dp). La couche de révélateur translucide microporeuse est déposée entre une couche d'imagerie qui comprend une couche de microcapsule photosensible et la couche de révélateur transparent à faible trouble. Les feuilles d'imagerie résultantes permettent d'obtenir des meilleurs résultats en ce qui concerne la saturation de couleur d'image, la vitesse de développement d'image et de mélange de colorants, et l'efficacité énergétique d'impression, ainsi qu'une meilleure résistance aux intempéries ou à la décoloration de l'image développée.
