Description

Inkjet recording ink composition for sublimation transfer and method of dyeing

The present invention relates to an ink composition for sublimation transfer for inkjet recording and a dyeing method using the same. More specifically, long term storage stability, improved print aptitude, reduced bleedind, long-term output stability, and user environmental pollution caused by sublimation transfer or fixation of the image shape printed on the print medium or the print medium. And a sublimation transfer ink composition for inkjet recording which prevents contamination of a chromosome and a dyeing method using the same.

The aqueous ink for inkjet recording is generally used in the form of dispersing a water-soluble dye solution or a water-insoluble colorant (pigment, dispersion dye) in a water-soluble solvent. Inkjet printing is a method of printing by ejecting ink droplets from a print head, unlike ordinary printing.

Two methods of dyeing using an inkjet recording sublimation transfer ink are a sublimation transfer method and a direct fixation method.

However, the sublimation transfer dyeing method prints an image shape on a printing medium [paper, coated paper, etc.] through an inkjet head with a sublimation transfer dye for inkjet recording. After overlapping, heat and pressure are applied to the image shape of the print medium to be transferred to and adhered to the object to be transferred.

On the other hand, the direct fastening dyeing method prints an image shape on a printing medium [polyester cloth, various textile cloths, etc.] through an inkjet head by sublimation transfer ink for inkjet recording, and indirectly heats the printing medium to disperse the sublimation in the printing medium. This is how dye is fixed.

When the sublimation transfer ink for sublimation transfer ink for inkjet recording is sublimed, a form in which a sublimable dispersion dye is dispersed in an aqueous solution containing water, a water-soluble solvent and a dispersing agent is generally used. When the transfer object is heated, sublimated and transferred to dye, the water-soluble solvent is volatilized together with water. This is different from inkjet inks for general printing purposes. In the dyeing method using a sublimation transfer ink, since the temperature is raised above the sublimation temperature of the sublimable dispersion dye and heated for a predetermined time, even a high boiling point organic solvent is volatilized. Especially in the case of high boiling point organic solvents, such as glycerin, when it volatilizes to air, since the temperature will fall to a condensation point, smoke-like vapor | steam is produced. This contaminates the user's working environment and causes contamination of the subject.

In addition, when the inkjet recording transfer ink is directly attached to a printing medium, a form in which a sublimable disperse dye is dispersed in an aqueous solution containing water, a water-soluble solvent and a dispersant is generally used. After printing, the printing medium is heat-fixed and dyed to fix the water-soluble solvent with water. This is different from inkjet inks for general printing purposes. In the dyeing method of directly fixing by using a sublimation transfer ink, since the temperature is raised above the sublimation temperature of the sublimable dispersion dye and heated for a predetermined time, even a high boiling point organic solvent is volatilized. At this time, the smoke-like vapor is contaminated by the user's working environment, the contamination of the stuck print media.

Performance items required for sublimation transfer ink and direct transfer ink for inkjet recording include 1) head clogging prevention, 2) ejection stability, 3) ink storage stability, 4) high quality recorded images, and 5) bleeding prevention. , 6) ink dryness, 7) high color density, and the like.

Since the inkjet recording method is ejected and printed by ink droplets through the nozzle of the printer head, head clogging may occur during long-term continuous output.

In the case of sublimation transfer ink and direct transfer ink, a water-soluble organic solvent is used to prevent head clogging to prevent head clogging. As the water-soluble organic solvent, glycols such as glycerin and polyethylene glycol, pyrrolidones and the like are used.

However, as described above, in the sublimation transfer dyeing method or the direct fixation dyeing method, it is necessary to heat the sublimation dye to a sublimation temperature for a certain period of time, so that the user's work environment is contaminated by volatilization and condensation when water-soluble solvent is used. The problem of contaminating the transfer object arises. Therefore, when selecting a water-soluble solvent, it is necessary to select a water-soluble organic solvent that satisfies the required performance without volatilization and condensation during sublimation transfer dyeing and direct fixation dyeing.

In the prior art, alkan-1,2-diol is used to improve the performance of inkjet recording inks, that is, to improve dispersion stability, improve wetting, reduce bleeding, flow, and leveling. Although there is an example used, there is no technique proposed for a technique for reducing the contamination of the working environment of the user and the contamination of the transfer object by using a sublimable disperse dye in an ink dispersed with a dispersant.
