A series of diphosphine ligands (L1–L5) containing bis-phosphino fragments and bis-amido groups as well as intensive electron-withdrawing F atoms were synthesized and fully characterized. The structures of the prepared complex of Pd-L5 demonstrate that as for L5, the incorporated two phosphino fragments participate in the chelation to the Pd center inversely along with two Cl– ligands to present a
The present disclosure refers to an inkjet ink composition comprising an ink vehicle including water; a white metal oxide pigment dispersed in the ink vehicle; and a latex binder, dispersed in the ink vehicle. The latex binder includes a first heteropolymer including two or more aliphatic (meth)acrylate ester monomers or two or more aliphatic (meth)acrylamide monomers; and a second heteropolymer including a cycloaliphatic monomer and an aromatic monomer. The present disclosure refers also to a printing method using such inkjet ink composition.
The present disclosure refers to an inkjet ink set comprising a black ink with a black pigment, a yellow ink with a yellow pigment, a cyan ink with a cyan pigment, a magenta ink with a magenta pigment and a white ink with a white pigment. At least one of the ink further contains a latex binder that is dispersed in the ink vehicle, and that includes a first heteropolymer including two or more aliphatic (meth)acrylate ester monomers or two or more aliphatic (meth)acrylamide monomers; and a second heteropolymer including a cycloaliphatic monomer and an aromatic monomer. The present disclosure refers also to a printing method using the ink set and to a system for printing the ink set.
Herein is described an inkjet printing system comprising: an aqueous pre-treatment fluid comprising a cationic polymer and a pre-treatment vehicle; an aqueous inkjet ink composition comprising a latex polymer comprising a (meth)acrylate or (meth)acrylamide polymer or copolymer, a pigment and an ink vehicle; and an aqueous inkjet overcoat composition comprising a latex polymer comprising a (meth)acrylate or (meth)acrylamide polymer or copolymer, a wax and an overcoat vehicle.
Described herein is an inkjet ink composition and an inkjet cartridge comprising an inkjet ink composition and an ink ejection device comprising a recirculation system. The inkjet ink composition may comprise a latex polymer and an ink vehicle. The ink vehicle comprising water and a co-solvent comprising a solvent having a boiling point in the range of about 170° C. to about 215° C. and a solvent having a boiling point of about 220° C. or more.
