Abstract
(EN)
The present disclosure is drawn to imaging kits, imaging systems, and methods of forming images. In one example, an imaging kit includes an imaging medium and a film-promoting fluid. The imaging medium includes a substrate, a color layer on the substrate, and an opaque concealing layer over the color layer. The color layer includes a pattern of color regions, wherein individual color regions include multiple adjacently-applied colors. The opaque concealing layer includes transparent polymer particles having a glass transition temperature from about 20 °C to about 120 °C. The film-promoting fluid includes a film-promoting additive that reduces the glass transition temperature of the transparent polymer particles after contact therewith.

La présente invention concerne des kits d'imagerie, des systèmes d'imagerie et des procédés de formation d'images. Dans un exemple, un kit d'imagerie comprend un support d'imagerie et un fluide filmogène. Le support d'imagerie comprend un substrat, une couche colorée sur le substrat et une couche de masquage opaque sur la couche colorée. La couche colorée comprend un motif de régions colorées, les régions colorées individuelles comprenant de multiples couleurs appliquées de manière adjacente. La couche de masquage opaque comprend des particules polymères transparentes ayant une température de transition vitreuse d'environ 20 °C à environ 120 °C. Le fluide filmogène comprend un additif filmogène qui réduit la température de transition vitreuse des particules polymères transparentes après contact avec celles-ci.
