Abstract
(EN)
The present disclosure is drawn to imaging media. In one example, an imaging medium includes a substrate and a color-forming layer on the substrate. The color-forming layer includes a pattern of color-forming regions. Individual color-forming regions include multiple adjacently-applied leuco dyes in a colorless state. The leuco dyes are developable to generate color upon contact with developer compound. The imaging medium is devoid of developer compound.

La présente invention concerne des supports d'imagerie. Dans un exemple, un support d'imagerie comprend un substrat et une couche chromogène sur le substrat. La couche chromogène comprend un motif de régions chromogènes. Des régions chromogènes individuelles comprennent de multiples colorants leuco appliqués de manière adjacente dans un état incolore. Les colorants leuco peuvent être révélés pour générer une couleur après contact avec le composé révélateur. Le support d'imagerie est dépourvu de composé révélateur.
