Ink composition described are suitable for ink jet printing (ink jet inks) and are highly effective for simultaneously imparting visible and fluorescent images. Figure 1 illustrated both visible and fluorescent images enabled by printing the inks of the invention on a substrate, one of a printed substrate in reflection under illumination by visible light and one of the same printed substrate fluorescing under ultraviolet excitation. The image scanned in reflection (102) was obtained by illumination the marking with visible light. The image scanned in fluorescence (104) is obtained by viewing the visible red- fluorescent emissions under ultraviolet (UV) illumination.
L'invention concerne une composition d'encre appropriée à l'impression au jet d'encre (encres de jet d'encre) et extrêmement efficace dans la génération simultanée d'images visibles et fluorescentes. La figure 1 de cette invention illustre à la fois des images visibles et fluorescentes obtenues par impression des encres de ladite invention sur un substrat, notamment, d'un substrat imprimé dans une réflexion sous éclairage de la lumière visible et du même substrat imprimé fluorescent sous excitation ultraviolette. Ladite image scannée dans la réflexion (102) est obtenue par éclairage du marquage avec la lumière visible. L'image scannée dans la fluorescence (104) est obtenue par visualisation des émissions rouges-fluorescentes visibles sous un éclairage ultraviolet (UV).
