Problems solved by technology

[0006] However, in order to obtain good color rendering, the surface of the recording medium needs to be made of polyester, and the types of recording media that can be applied are limited.
In some cases, the color development of sublimation dyes and disperse dyes can be improved by increasing the heat treatment temperature, but depending on the recording medium, the recording medium itself may melt or cause unexpected discoloration due to carbonization, etc.

Embodiment 1

[0179] First, C.I. Disperse Yellow 232 as a specific dye, MD-1480 (manufactured by Toyobo Co., Ltd.) as an aqueous dispersion of self-emulsifying polyester having a glass transition temperature of 20°C, glycerin, and triethylene glycol monobutyl ether , triethanolamine, Olfine E1010 (manufactured by Nissin Chemical Industry Co., Ltd.) as a surfactant, and pure water were mixed at a predetermined ratio, and stirred at a speed of 3000 rpm by a high-speed dispersion mixer (manufactured by Silverson Co., Ltd.) to form a slurry.

[0180] Next, the produced slurry and glass beads with a diameter of 0.5 mm were stirred and dispersed under water cooling using a bead mill (LMZ015, Ashizawa Finetech Ltd.).

[0181] Thereafter, the glass beads were removed, and heat treatment was performed at 50° C. for 10 hours. Accordingly, an inkjet ink was obtained as an aqueous inkjet composition containing polyester particles dyed with a dye.

[0182] In addition, the polyester contained in MD-148...

Embodiment 2～9

[0184] The type of specific dye, the type of polyester, and the ratio of each component were adjusted to achieve the composition shown in Table 1, and the conditions of the heat treatment were set as shown in Table 1, except that it was produced in the same manner as in Example 1 above. inkjet ink.

Abstract

The present application provides an aqueous ink jet composition, a method for producing the aqueous ink jet composition, and a method for producing a recorded material, the aqueous inkjet compositionbeing capable of exhibiting excellent color rendering properties with respect to various recording media, the method for producing an aqueous inkjet composition is capable of efficiently producing anaqueous inkjet composition capable of exhibiting excellent color rendering properties with respect to various recording media. The method for producing the recorded material can produce the recorded material with excellent color rendering property. The aqueous ink jet composition according to the present invention comprises water, a dye comprising at least one of a sublimation dye and a disperse dye, and polyester particles comprising a polyester-containing material, wherein at least a part of the polyester particles are dyed by the dye.

Description

technical field [0001] The present invention relates to an aqueous inkjet composition, a method for producing the aqueous inkjet composition, and a method for producing a recorded matter. Background technique [0002] In recent years, the use of inkjet printing is gradually expanding, and it is also used in commercial printing, text printing, etc. in addition to office and home printing machines. [0003] Furthermore, inkjet inks containing sublimable dyes and disperse dyes having sublimation properties have also been used. [0004] As such an inkjet ink, it can be used in the following methods: after applying ink to a recording medium to be dyed, a direct printing method in which a dye is colored by heat treatment such as steam; after applying a dye ink to an intermediate transfer medium , a thermal transfer printing method in which dye is sublimated and transferred from an intermediate transfer medium side to a recording medium to be dyed using heat (for example, refer to...
