A method for producing a printed product is provided. The method capable of producing the printed product is superior in a friction fastness and a texture. And, a printing system is also provided. The method includes a printing step in which an ink composition for inkjet, containing a colorant and a crosslinkable binder component, is inkjet-printed onto a textile good to obtain a print body; and a heat-treatment step in which, by heat-treatment of the print body with steam, the crosslinkable binder component is caused to melt or soften, and to crosslink to be a film, thereby fixing the colorant to fibers of the textile good. The printing system includes a printing apparatus and a heat-treatment equipment with which a print body after printing is heat-treated with steam.

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.
