  • Aqueous reaction liquid composition, ink set comprising such aqueous reaction liquid composition and method of printing using such aqueous reaction liquid composition
    Patent number: 10138389
    Abstract: The present invention relates to an aqueous reaction liquid comprising a salt, a first surfactant being an amphoteric surfactant and a second surfactant being a non-ionic surfactant, preferably selected from the group consisting of hydrophilic silicones (such as polyalkylene oxide modified silicones/polyether modified silicones), alkoxylated alcohols, fluorosurfactants, polyether modified silicone surfactants and polyethyleneoxides. Reaction liquids according to the present invention show improved spreading on print substrates when applied, which is beneficial when the reaction liquid is applied by an ink jet method. The present invention further pertains to an ink set comprising such a reaction liquid and a method of printing using such an ink set.
