Problems solved by technology

[0005] However, C.I. Pigment Red 122 has the disadvantages of being expensive, difficult to disperse, and poor dyeing ability, especially in fabrics, and the printed surface tends to appear white due to fabric fluff
Also, since the resulting red hue is close to magenta, an attempt to develop red by using a yellow ink and a magenta ink containing this C.I. Pigment Red 122 cannot give a bright red color

Embodiment

[0042] The present invention will be described in detail by the following examples.

[0043] (1) Preparation of pigment ink

[0044] Fill the disperser (sand mill, Igarashi Machinery Co. Ltd. (Igarashi Machinery Co., Ltd.)) with glass beads or zirconium beads (1 mm diameter) with a diameter of 1 mm, followed by 10 wt % of C.I. Pigment Red 213 as a pigment, 35 wt % glycerin as a water solvent and balanced pure water were charged into the disperser, and then these mixtures were crushed for 3 to 4 hours. The product was centrifuged (10000 rpm, 30 minutes) to remove coarser particles. Adding the 4.0wt% water emulsion of the 10% aqueous solution of the acrylic resin emulsion to which the pH is adjusted to 8 to 10, the magenta ink (pigment concentration 10wt% in the volume average particle diameter of the dispersed pigment) in the range of 50nm to 200nm ).

[0045] The same inks were prepared using the inks listed in Table 1, resulting in three magenta inks, three yellow inks and...

Abstract

The invention provides an ink-ejecting ink for fabric printing, which comprises printing ink containing basic fuchsin C.I. paratonere 213, and yellow printing ink to realize that, the colority a* and b* of the L*a*b* color series when printing is conducted to fabrics through ink-jet printing method can meet the requirement of -18<=a*<=0, 50<=b<=80. As a result, red color can be achieved on the printing portions of the fabrics.

Description

technical field [0001] The present invention relates to an ink set for textile printing by an inkjet method, and to an inkjet method using the ink set. technical background [0002] Conventionally, in the case where all colors are formed by the inkjet method and water-soluble dyes of each color are used as colorants, ink combinations containing 3 or 4 colors, i.e., yellow ink, magenta ink, Blue ink and black ink if desired. From the viewpoint of weather resistance and water resistance, in addition to water-soluble dyes, pigment inks using pigments have also been adopted in recent years. Printing on textiles is likewise possible by the inkjet method using pigmented inks. [0003] However, when using pigment inks, it is more difficult to reproduce vivid hues than when using dye inks, and the range of hues that can be developed is narrower. Therefore, active research is being conducted on the use of mixed pigments as colorants, which can allow vivid hues to be obtained by in...
