An aqueous ink including a pigment, a fixing resin, and water. The fixing resin includes a constitutional unit derived from (meth)acrylic acid (A), a constitutional unit derived from a cycloalkyl (meth)acrylate (B), and a constitutional unit derived from an alkyl (meth)acrylate (C) whose homopolymer has a glass transition temperature of not higher than 0 C. A content of the constitutional unit derived from the (meth)acrylic acid (A) is not less than 6% by mass and not more than 25% by mass based on the whole constitutional units of the fixing resin, a content of the constitutional unit derived from the cycloalkyl (meth)acrylate (B) is not less than 30% by mass and not more than 90% by mass based on the whole constitutional units of the fixing resin, and a glass transition temperature (Tg) of the fixing resin is not lower than 20 C. and not higher than 40 C.

In an example of a method for three-dimensional (3D) printing, build material layers are patterned to form an intermediate structure. During patterning, a binding agent is selectively applied to define a patterned intermediate part. Also during patterning, i) the binding agent and a separate agent including a gas precursor are, or ii) a combined agent including a binder and the gas precursor is, selectively applied to define a build material support structure adjacent to at least a portion of the patterned intermediate part. The intermediate structure is heated to a temperature that activates the gas precursor to create gas pockets in the build material support structure.

An aqueous ink-jet ink which contains an aqueous vehicle, a dispersed binder, and one or more nonionic surfactants. The aqueous vehicle contains solvents with boiling points less than 200 C., or solvents with boiling points greater than 200 C. and having a solubility of water in solvents of less than 50% by weight. The ink is particularly advantageous for printing on coated offset media with.

A flake-less molecular ink suitable for printing (e.g. screen printing) conductive traces on a substrate has 30-60 wt % of a C.sub.8-C.sub.12 silver carboxylate or 5-75 wt % of bis(2-ethyl-1-hexylamine) copper (II) formate, bis(octylamine) copper (II) formate or tris(octylamine) copper (II) formate, 0.1-10 wt % of a polymeric binder (e.g. ethyl cellulose) and balance of at least one organic solvent. Conductive traces formed with the molecular ink are thinner, have lower resistivity, have greater adhesion to a substrate than metal flake inks, have better print resolution and are up to 8 times less rough than metal flake inks. In addition, the shear force required to remove light emitting diodes bonded to the traces using Loctite 3880 is at least 1.3 times stronger than for commercially available flake-based inks.

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.
