[Industrial Application Field] The present invention relates to an ink composition for inkjet or spray dyeing, and in particular to an inkjet or spray dyeing composition (hereinafter abbreviated as inkjet) that has excellent nozzle ejection properties and dispersion stability, and can provide an excellent bleed prevention effect. )
The present invention relates to an ink composition for use in printing. [Prior Art] With the recent development of color inkjet printing technology, attempts have been made to utilize it for textile printing of fabrics, as shown in, for example, Japanese Patent Application Laid-Open No. 1897-1897. If you try to use it on fabric, there will be problems such as colors appearing lighter and bleeding more than when printing on paper. Furthermore, the types of fabrics to be dyed are more diverse than paper. Due to these reasons, it is difficult to say that a common bleed prevention means and an inkjet ink for fabrics that are highly effective have yet been developed. Examples of dispersants for water-insoluble dyes and pigments include JP-A-Sho
Nonionic dispersants are used in 56-128370 and 56-128371, and water-insoluble dyes are used in JP-A-51-49982.
A water-soluble resin-based dye composition with a dispersant and a water-soluble resin is disclosed. These are intended for general textile printing and continuous dyeing applications, but
When these dye compositions are used as they are as inkjet inks, various problems arise.
For example, ink containing a water-soluble resin generally has an increased viscosity, which significantly impairs ejection properties. On the other hand, if the viscosity is low, the dispersion stability of the disperse dye deteriorates, making continuous discharge difficult, lacking uniformity, and of course causing even greater bleeding. According to the studies of the present inventors, the main properties that an ink composition for an inkjet using water-insoluble dyes and pigments should have are: (1) Low viscosity (preferably 30 cps or less) (2) Low viscosity and good dispersion stability, (3) particle size of 1μ or less, (4) surface tension in the range of 40 to 70 dyn/cm, and (5) anti-bleeding properties. Ink composition, etc. These properties are significantly different from those required of conventional textile printing and continuous dyeing compositions, and no inkjet composition has been found that satisfies all of the above (1) to (5). is the current situation. [Problems to be Solved by the Invention] An object of the present invention is to provide an ink composition for inkjet or spray dyeing that has low viscosity and excellent dispersion stability, and can also provide anti-bleeding properties. [Means for solving the problems] The present invention has the following configuration. An ink composition for inkjet or spray dyeing, characterized in that it contains a water-insoluble dye and pigment and a dispersant represented by the following general formula as essential components. However, Q is a benzene or naphthalene nucleus, R 1 is a group having a benzene or naphthalene nucleus, m is 2 to 5, R 2 is a non-aromatic group such as lower alkyl or halogen, n is 0 to 3, and Z is The divalent substituent M represents ammonia, amine and monovalent metal. The inkjet ink of the present invention has a low viscosity, good dispersion stability, and excellent ejection properties, and also has a flocculating effect on fabrics, especially fabrics pretreated with cationic compounds and/or metal salts. Therefore, it is possible to impart a remarkable ink bleed prevention effect. It has been known that water-soluble dye ink is used to pre-treat paper with metal salts or cationic substances, but surprisingly, the present inventors found that the water-soluble dye ink of the present invention The level of bleed prevention obtained using insoluble dye and pigment inks is even higher than that obtained using water soluble dyes. The present invention will be explained in detail below. The dispersant for water-insoluble dyes and pigments of the present invention is a dispersant that easily contains dyes and pigments. In the ink of the present invention, the dyes and pigments dispersed on the pretreated fabric aggregate and separate into water and dyes and pigments, and even if water that does not contain dyes and pigments is diffused onto the fabric, the dyes and pigments are only slightly diffused. It is possible to prevent smearing. The present invention is characterized by the discovery of a specific dispersant that clearly exhibits such properties. That is, the dispersant of the present invention has an aromatic ring as a hydrophobic group and a sulfonic acid group (-
SO 3 M) or sulfate ester base (-O-
Its essence is that it is an anionic dispersant with SO 3 M). In the above, M is ammonia, amine, monovalent metal (alkali metal), etc., and ammonia and amine are particularly preferred. The aromatic ring is preferably a monocyclic aromatic ring, that is, a benzene nucleus, but may also be a naphthalene ring or the like. The dispersant of the present invention binds to a fabric pretreated with a cationic compound or/and a metal salt, coagulates the ink, and imparts smear prevention properties. Representative examples of the dispersant of the present invention include those represented by the following general formula. Q is a benzene nucleus or a naphthalene nucleus, R 1 is a group containing a benzene nucleus or a naphthalene nucleus, m is 2 to 5, R 2 is a non-aromatic group such as lower alkyl or halogen, n is 0 to 3, and Z is A divalent substituent, M represents ammonia, an amine, or a monovalent metal. Specific examples of the dispersant represented by the above general formula include the following. At least one type of these dispersants may be included. In the present invention, a small amount of a dispersant other than the present invention can be used as an auxiliary, but in order to obtain the effects of the present invention, the dispersant of the present invention must be the main component. Among the dispersants of the present invention, ammonium or amine salts in particular are subject to or easily subject to change during fixation processes such as dry heat or wet heat, and approach insoluble dispersants. Therefore, there is relatively little decrease in color fastness even without washing, and the so-called "kiwatsuki" phenomenon that leaves water marks when water is dropped is significantly reduced.
It is a particularly preferred dispersant. The amount of the dispersant of the present invention used is 5 to 100 weight (%), preferably 10 to 50 weight (%), based on the water-insoluble dye and pigment. The dispersion treatment can be carried out using a known ball mill, colloid mill, sand grinder, or the like. Examples of water-insoluble dyes and pigments in the present invention include disperse dyes, oil-soluble dyes, and pigments. The concentration of water-insoluble dyes and pigments is usually 0.01-20%. The average particle size of the water-insoluble dye and pigment is 1μ or less, preferably 0.5μ or less, and the smaller the particle size, the better the exhaustability or dispersion stability of the dye. Ink viscosity is very important in inkjet dyeing methods. In other words, the ejection performance improves as the ink viscosity decreases, and therefore, the ejection performance improves as the ink viscosity decreases.
10cps or less is good. Also, the surface tension is 40~
70 dyne/cm is best; if it is less than 40 dyne/cm, bleeding will be large and uneven discharge will likely occur. In the present invention, the composition of the inkjet ink containing water-insoluble dyes and pigments includes the above-mentioned water-insoluble dyes and pigments, the dispersant, and water, as well as water-soluble solvents such as glycerin, propylene glycol, and ethylene glycol, and physical property modifiers. (viscosity, PH, surface tension, conductivity), preservatives, bactericidal agents, chelating agents, binders, etc. Furthermore, for the purpose of preventing bleeding, an anti-bleeding agent that causes little increase in viscosity and does not impede the dispersion stability of the ink, such as a water-dispersible polymer resin (eg, a water-dispersible polyester resin), may be contained. The coloring method using the ink composition of the present invention is a droplet dyeing method, that is, an inkjet method or a spray method. Any method may be used as the inkjet method, and for example, any conventionally known appropriate method such as (1) pressure vibration type, (2) pressure pulse type, and (3) electrostatic acceleration type can be used. Inkjet droplets usually have a diameter of 20~
150μ and a resolution of about 2 to 16 lines/mm are preferably used. The spray method may be any conventionally known method such as a one-fluid type, a two-fluid type, or an electrostatic spray method. Both inkjet and spray methods can be used for both printing and plain dyeing. After dyeing, a normal fixing method or a washing step may be incorporated as necessary. The present invention will be specifically illustrated in Examples below. [Example 1] A satin fabric made of polyester fibers was pretreated with the cationic compound and metal salt shown below. (1) Calcium chloride 50g/ (2) Neofix RS (polyamine type) (manufactured by NICCA Chemical Co., Ltd.) 50g/ were padded (squeezing ratio: 40%) and dried (100°C). Next, 10% of CI Disperse Red 92 was added as a disperse dye, and 50% of the dispersant shown in Table 1 was added to the dye.
%, ion-exchanged water was added to bring the total volume to 200 c.c., and then 200 c.c. of glass beads (1 mmφ) were added, followed by dispersion treatment using a sand grinder for 30 hours. next,
Using this liquid, a disperse dye ink having the following composition was prepared. CI Disperse Red 92 (10%) 50% Propylene glycol 20% Ion exchange water 30% This ink was filtered through a 5μ filter and degassed under reduced pressure before use. Printing was carried out using this ink under the following ink jet conditions. Method: On-demand nosol diameter: 60μ Applied voltage: 50V Distance between nozzle and fabric: 1mm Resolution: 8 lines/mm The ink was applied with an inkjet and then fixed at 180°C for 10 minutes to develop color. .
The dot diameter of the dyed product was evaluated. Table 1 shows the results.
Shown below. Together, the dispersibility, average particle size of the ink,
Ink viscosity was also measured. The results are shown in Table 1. Regarding the dispersibility, after the dispersion treatment, it was filtered using a 5μ cut filter, and the dispersibility (%) was determined from the residue. The ink viscosity was determined using an E-type viscosity type (100 rpm, 35°C), and the average particle size was determined using a centrifugal separation method. [Comparative Example] For comparison, a fabric without pretreatment was prepared (Comparative Example 1). Moreover, as a dispersant other than the present invention, Comparative Example 2
indicates a phosphoric acid ester, and Comparative Example 3 indicates a dispersant of tamor, which is the most common dispersant. It was treated in the same manner as in Example 1. The results are shown in Table 1.
