There is provided a set including: a water-based ink for ink-jet recording including a dye and water; and a treatment agent including a cationic polymer emulsion which includes a cationic polymer including a urethane structure. There is provided a recording method for recording on a recording medium which is fabric or recording paper by using the set.

An ink jet ink composition set includes a white ink jet ink composition and a nonwhite ink jet ink composition. The white ink jet ink composition contains a white pigment, resin particles, and water, and the nonwhite ink jet ink composition contains a nonwhite pigment, resin particles, and water. The white pigment has cation responsiveness, and the absolute value of zeta potential of the white pigment is lower than the absolute value of zeta potential of the nonwhite pigment.

The invention concerns a method for decoloring of a textile material, the method comprising the steps of: providing a textile material; providing an alkaline solution containing one or more anionic polyelectrolytes; treating the textile material in the alkaline solution during a treatment period; and recovering at least some of the textile material from the alkaline solution.

A transfer-printing ink is ejected onto a transfer paper base on an ink-jet recording device when transfer paper is prepared, and is transferred from the transfer paper to cloth when the transfer paper with the cloth laid over it is heated. The ink contains a pigment, an anionic fixing resin, and a volatile amine as a neutralizer for neutralizing the fixing resin. The average particle diameter of the pigment is 30 nm to 150 nm. The pigment-to-fixing resin mass ratio is 1:1 to 1:5. The added amount of the volatile amine is 0.8 to 1.5 times the neutralization equivalent.

A pretreatment liquid for use in ink jet pigment textile printing contains at least one of a resin dispersion and a cross-linker, a lubricant, and water.

A treatment agent for image recording includes a cationic polymer emulsion and a cationic surfactant. A set usable for recording on a fabric includes a water-based ink for ink-jet recording including a colorant and water; and the treatment agent for image recording. A recording method for recording on a fabric by using the set includes: applying the treatment agent for image recording to the fabric; drying the treatment agent for image recording applied to the fabric; and jetting the water-based ink onto the fabric by an ink-jet system.

There is provided a treatment agent for image recording including: a cationic polymer emulsion; and a water-soluble organic solvent including a glycol-based water-soluble organic solvent of which boiling point is not more than 200 C. The treatment agent satisfies the following condition (1): 20A60. In the condition (1), A: a content amount (% by mass) of the glycol-based water-soluble organic solvent, of which boiling point is not more than 200 C., in an entire amount of the treatment agent for image recording.

There is provided a set including: a water-based ink for ink-jet recording including a dye and water; and a treatment agent including a cationic polymer emulsion which includes a cationic polymer including a urethane structure. There is provided a recording method for recording on a recording medium which is fabric or recording paper by using the set.

A set includes: a water-based black pigment ink for ink-jet recording; a water-based yellow dye ink for ink-jet recording; a water-based magenta dye ink for ink-jet recording; a water-based cyan dye ink for ink-jet recording; and a treatment agent. The water-based black pigment ink for ink-jet recording includes a carbon black and water; the water-based yellow dye ink for ink-jet recording includes a yellow dye and water; the water-based magenta dye ink for ink-jet recording includes a magenta dye and water; the water-based cyan dye ink for ink-jet recording includes a cyan dye and water; and the treatment agent includes a cationic polymer emulsion.

The present teachings include a process, system and article for forming a printed image on a textile. In some embodiments, the process includes coating the textile with a layer of polydiallyldimethyl ammonium chloride cationic polymer and coating the textile with the layer of polydiallyldimethyl ammonium chloride cationic polymer with a layer of poly-4-styrene sulfonate anionic polymer. The process can further include applying an ink composition to the textile having the layer of polydiallyldimethyl ammonium chloride cationic polymer layer and the layer of poly-4-styrene sulfonate anionic polymer, forming an image.
