Title (EN) INKJET PRINTING SYSTEM AND INK
(FR) SYSTÈME D'IMPRESSION À JET D'ENCRE ET ENCRE
Abstract: front page image
(EN)An inkjet printing system comprises an inkjet printer responsive to digital signals and containing an ink composition comprising: (a) water, (b) dispersed pigment particles, (c) a humectant, and (d) a polyurethane additive having at least a first soft segment having siloxane groups, the additive having a weight average molecular weight of at least 10,000 daltons and a sufficient number of acid groups to provide an acid number greater than 60. An improved combination of scratch resistance and jetability is obtained.
(FR)La présente invention concerne un système d'impression à jet d'encre comprenant une imprimante à jet d'encre sensible à des signaux numériques et contenant une composition d'encre comprenant : (a) de l'eau, (b) des particules de pigments dispersées, (c) un humectant, et (d) un additif polyuréthane ayant au moins un premier segment souple ayant des groupes siloxane, l'additif ayant un poids moléculaire moyen en poids d'au moins 10 000 daltons et un nombre suffisant de groupes acides afin de fournir un indice d'acidité supérieur à 60. On obtient aussi une combinaison améliorée de résistance à la rayure et de capacité à l'utilisation en jet d'encre.
