(FR) Procédés d'impression utilisant des encres réactives
Abstract
(EN)
Reactive inks and methods of generating an image on a substrate using both reactive and heat activated inks are presented. An image is printed on a substrate, without reacting the reagents in the ink. Subsequently, the reagents are reacted to fix the image to a substrate, with substantial permanency and fastness. Sublimation or similar heat activated dyes are printed are also printed on the substrate. The sublimation or similar heat activated dyes are activated, and have an affinity for polymer that is applied to the substrate.

Cette invention concerne des encres réactives et des procédés permettant de générer une image sur un substrat à l'aide à la fois d'une encre réactive et d'une encre activée à la chaleur. Selon cette invention, il convient d'abord d'imprimer une image sur un substrat sans faire réagir les réactifs dans l'encre, après quoi on fait réagir les réactifs de façon que l'image soit fixée sur un substrat avec une durabilité et une solidité substantielles. Des colorants à sublimation ou à activation thermique similaires sont également imprimés sur le substrat. Les colorants à sublimation ou à activation thermique similaires sont activés et présentent une affinité pour un polymère qui est appliqué sur le substrat.
