An object is to provide a method for storing or transporting an aqueous white ink composition for inkjet that does not cause precipitation of a pigment therein during storage for a long period or transport, and allows the pigment to be easily redispersed even if precipitation occurs. As means for solving the problems, a storing method is provided that includes placing an aqueous white ink composition for inkjet containing titanium oxide and a pigment dispersant in a tank and maintaining the entire aqueous white ink composition for inkjet in the tank at a temperature of −5 to −35° C.

Methods for forming latexes are provided. In an embodiment, such a method comprises adding a monomer emulsion comprising water, a monomer, an acidic monomer, a hydrophilic monomer, a difunctional monomer, a first reactive surfactant, and a chain transfer agent, to a reactive surfactant solution comprising water, a second reactive surfactant, and an initiator, at a feed rate over a period of time so that monomers of the monomer emulsion undergo polymerization reactions to form resin particles in a latex. The reactive surfactant solution does not comprise monomers other than the second reactive surfactant, the reactive surfactant solution does not comprise a resin seed, and the monomer emulsion does not comprise the resin seed. The latex is characterized by a viscosity in a range of from about 10 cP to about 100 cP as measured at a solid content of about 30% and at room temperature. The latexes are also provided.

This disclosure relates to novel aqueous ink-jet inks having improved image properties containing an aqueous vehicle, a cross-linked pigment dispersion, and a cross-linked polyurethane binder. The inks are particularly advantageous for printing on textile.

The present disclosure provides a white ink including an aqueous ink vehicle; from 5 wt % to 50 wt % of a white metal oxide pigment having an average particulate size from 75 nm to 2,000 nm and a refractive index of 1.8 to 2.8; and from 0.1 wt % to 15 wt % of fumed oxide particulates having a tertiary agglomerated average particulate size from 20 nm to 750 nm and a refractive index of 1.1 to 1.6. The white ink further includes a polymeric dispersant associated with a surface of the white metal oxide pigment.

A surface treatment liquid composition for a substrate is provided. The surface treatment liquid composition includes a water-soluble salt, water, and a resin particle including a resin having a structural unit represented by the following formula (1):
