CA 2420552

The present invention provides nanoparticle based recording mediums, inks and ink compositions, methods of making nanoparticle based recording mediums and inks, nanoparticles and methods for making nanoparticles, methods for stabilizing colorants against electromagnetic radiation (including radiation in the visible wavelength range), methods for enhancing the substrate independent durability performance of inks, and methods for color density control. The nanoparticle based inks deliver better color, color density control, improved printability, enhanced durability, and increased lightfastness, and are capable of being printed on woven and non-woven fabrics and paper products without special treatment or other limitations.

La présente invention concerne des supports d'enregistrement, des encres et des compositions d'encres à base de nanoparticules, des procédés de fabrications des supports d'enregistrement et encres à base de nanoparticules, des nanoparticules et des procédés de fabrication des nanoparticules, des procédés de stabilisation des colorants contre le rayonnement électromagnétique, y-compris le rayonnement dans les plages de longueurs d'ondes visibles, des procédés pour renforcer le rendement de durabilité des encres indépendamment du substrat, et des procédés de gestion de la densité chromatique. Les encres à base de nanoparticules fournissent de meilleures couleurs, une régulation de la densité chromatique, une meilleure imprimabilité, une durabilité renforcée, et une meilleure tenue à la lumière, tout en se prêtant à l'impression sur des tissus tissés et non-tissés et des produits de papier, sans traitement spécial ou autres limitations.
