A printing method for printing a printing medium includes a non-white ink application step of applying an aqueous non-white ink composition containing a non-white coloring material onto the printing medium, and a white ink application step of applying an aqueous white ink composition containing a white coloring material onto the non-white ink composition on the printing medium to form a superimposed region. The non-white ink composition and the white ink composition each have an organic solvent content limited to 15% or less relative to the total mass of the corresponding ink composition. The mass ratio of the white ink composition to the non-white ink composition in the superimposed region is 1.5 or more in a portion to which the non-white ink composition is applied in an amount largest in the superimposed region.

An aqueous ink for inkjet printing containing a colorant, a resin, a wetting agent, a surfactant, and water, in which the wetting agent contains a polyhydric alcohol at 60% by mass or more relative to the total amount of the wetting agent, the polyhydric alcohol having a solubility parameter value of 11.0 to 15.0, the resin contains a (meth)acrylic resin having a polydimethylsiloxane chain structure and a polyether chain structure on a side chain and a weight average molecular weight of 2,000 to 30,000, the (meth)acrylic resin is water soluble, the ratio of the blend amount of the polyhydric alcohol to the blend amount of the (meth)acrylic resin is 1500:1 to 6:1 by mass ratio, and the content of fluorine atoms in the total amount of the aqueous ink is 500 mass ppm or less.

The present disclosure describes ink compositions having a polyurethane binder that can be used for textile printing. In one example, an ink composition can include water, an organic co-solvent, a colorant, and a polyurethane binder. The polyurethane binder can include pre-polymer segments that include polymerized monomers of a diisocyanate, a graft diol, a polymeric diol, and an acid-containing diol. The graft diol can include thioglycerol having a polymer sidechain replacing a hydrogen atom on a sulfur atom of the thioglycerol. The polymer sidechain can include a polymerized monomer of an acrylate ester, a methacrylate ester, a styrene, or a combination thereof. The polyurethane binder can also include chain extenders connecting the pre-polymer segments. The chain extenders can include a polymerized sulfonate-containing diamine.
