Title (EN) PRE-TREATMENT FIXING FLUID
(FR) FLUIDE DE FIXATION DE PRÉ-TRAITEMENT
Abstract:
(EN) A pre-treatment fixing fluid for an offset coated medium is disclosed. The pre-treatment fixing fluid includes calcium-containing cationic crashing agents consisting of calcium propionate and calcium nitrate, wherein the calcium propionate is present in an amount ranging from about 0 wt% to about 10 wt%, and wherein the calcium nitrate is present in an amount ranging from about 15 wt% to 0 wt%, both based on the total wt% of the pre-treatment fixing fluid. The pre-treatment fixing further includes a co-solvent, a surfactant, and a balance of water. The surfactant is selected from the group consisting of a first surfactant having a first hydrophilic lipophilic balance (HLB) value within a hydrophobic range and a combination of the first surfactant and a second surfactant having a second HLB value within a water dispersible range.
(FR) L'invention concerne un fluide de fixation de pré-traitement pour un support revêtu décalé. Le fluide de fixation de pré-traitement comprend des agents d’écrasement cationiques contenant du calcium qui sont constitués de propionate de calcium et de nitrate de calcium, dans lequel le propionate de calcium est présent en une quantité allant d’environ 0 % en poids à environ 10 % en poids, et dans lequel le nitrate de calcium est présent en une quantité allant d’environ 15 % en poids à 0 % en poids, tous les deux sur la base du pourcentage en poids total du fluide de fixation de prétraitement. Le fluide de fixation de pré-traitement comprend également un co-solvant, un agent de surface, et un complément en eau. L'agent de surface est sélectionné dans le groupe constitué par un premier agent de surface ayant une première valeur d'équilibre lipophile hydrophile (HLB) dans les limites d'une gamme hydrophobe et une combinaison du premier agent de surface et d'un deuxième agent de surface ayant une deuxième valeur HLB dans une gamme hydrodispersable.
