    Abstract: The present disclosure directs to the technical field of epoxy resins, and particularly relates to an antichlor and a preparation method as well as an application thereof, for solving problems in existing chlorine removal methods that separation efficiency of an epoxy resin containing hydrolyzable chlorine is low, lots of energy needs to be consumed in the separation process, molecular distillation equipment is expensive and requirements on vacuum degree and material tightness are high. The antichlor is a polymer containing keto-carbonyl groups. The preparation method includes: adding a mixed solution of styrene and ketene into a reactor containing an organic solvent; adding an initiator, a coupling agent and an anti-gelling agent into the reactor under an atmosphere of shielding gas; controlling the styrene and ketene to perform a polymerization reaction under first preset reaction conditions; and removing the organic solvent after completion of the polymerization reaction, thereby obtaining the antichlor.

    Abstract: An inkjet ink includes: an ink vehicle; a colorant; and an acetylenic compound having an alkoxylated hydroxyl group, wherein the hydroxyl group is a primary or secondary hydroxyl group and the acetylenic compound is absent a lipophilic group. Printheads having resistive heater elements exposed to such inks have prolonged lifetimes compared to reference inks.

    Abstract: An inkjet aqueous pigment dispersion which achieves high pigment concentration, exhibits favorable redispersion properties after drying, and does not exhibit changes in ink properties even when stored for a long time; and an ink composition using the aqueous pigment dispersion. The inkjet aqueous pigment dispersion contains a pigment, a liquid medium, and a polymer dispersion agent which is an A-B block polymer obtained by copolymerization using a mixture of an organic tellurium compound represented by formula (1) and an organic ditellurium compound represented by formula (2) as a polymerization initiator. The monomer for configuring the A block is at least one type of monomer represented by formula (3), and the monomer for configuring the B block is benzyl methacrylate and/or benzyl acrylate.
