Problems solved by technology

Therefore, there is such a disadvantage that even if the nanoparticles can be dispersed under high concentration conditions, a large amount of dispersion aid must be used, so in inks with low viscosity and extremely low content of polymer compounds such as inkjet ink In such cases, the techniques mentioned above are difficult to apply directly
However, when this method is adopted, there is a problem that the pigment is less efficiently surrounded by the resin and is difficult to redisperse because the particles undergo a form in which the particles are strongly aggregated together in an aqueous medium at once. (For example, see Patent Documents 3, 4, etc.)
[0007] In addition, there is also a method in which, in order to make a water-based paste, the nano-pigment particles prepared in a water-based solvent are directly filtered with a filter in the state of primary particles or filtered with a filter in a state of aggregation. filter, but there is such a problem in this method: it takes a lot of time to filter, which is very inefficient in industry, and the operation is complicated
However, since the aggregates at the time of separation are hydrophilic, it takes a lot of time to filter

Embodiment 1

[0286] [Preparation of aqueous dispersion of organic nano-pigment particles]

[0287] C.I. Pigment Red 254 (45 parts by mass) and the above-mentioned Exemplified Compound O-1 (45 parts by mass) were added to dimethyl sulfoxide (DMSO) (953 parts by mass), and stirred. A 26% by mass tetramethylammonium hydroxide aqueous solution (45 parts by mass) was added to this solution to prepare a pigment solution A. Separately, water (4000 parts by mass) containing acetic acid (7.6 parts by mass) was prepared as the pigment insoluble solvent B.

[0288] While stirring the above-mentioned pigment insoluble solvent B at 30° C. with a GK-0222-10 Ramond agitator (trade name) manufactured by Fujisawa Pharmaceutical Industry Co., Ltd. at a speed of 500 rpm, the NP- KX-500 type large-capacity pulseless pump (trade name) injects the above-mentioned pigment solution A into the pigment-insoluble solvent B with a flow rate of 100ml / min, and the injection time is 4 minutes and 4 seconds, so that the...

Embodiment 2

[0309] The same operation as in Example 1 was carried out, except that the above-mentioned exemplary compound O-1 used in Example 1 was changed to O-3. The same evaluation test as in Example 1 was performed on the obtained non-aqueous dispersion of organic nano-pigment particles (pigment dispersion composition B). The results are shown in Table 1.

Embodiment 3

[0311] The same operation as in Example 1 was carried out, except that the above-mentioned exemplary compound O-1 used in Example 1 was changed to O-10. The same evaluation test as in Example 1 was performed on the obtained non-aqueous dispersion of organic nano-pigment particles (pigment dispersion composition C). The results are shown in Table 1.

Abstract

The present invention provides an organic nanometer pigment particle non-aquosity dispersing object with dispersibility and decentralization stability, obtained by a following method. The method does need multifarious processes, includes steps of transferring the organic nanometer color microparticle in a aquosity medium into non-aquosity aggregate filtrated easily, separating the aggregate so asto obtain organic nanometer color particle hydrophobicity aggregate with high efficiency, then dispersing the hydrophobicity aggregate in the non-aquosity medium so as to product the organic nanometercolor particle non-aquosity dispersing object. the present invention provides an organic color combination, containing organic color microparticle and high molecular compound containing repetitive units represented by the follow general formula (1) and / or repetitive units represented by the general formula (2), in the formula, A1 represents hydrogen atom or methyl; X1 represents heterocyclic radical connected with the repetitive units through the carbon atom.

Description

technical field [0001] The present invention relates to an organic pigment composition, a method for producing the same, and a colored photosensitive resin composition and a color filter using the organic pigment composition. Background technique [0002] Among nano-sized particles, organic pigments are used, for example, as materials for paints, printing inks, toners for electrophotography, inkjet inks, and color filters. Among them, pigments for inkjet inks and pigments for color filters are exemplified as organic pigments that require high performance and are particularly important practically. [0003] Methods for producing organic particles include gas phase method, liquid phase method, laser ablation method, and the like. Among them, the liquid-phase method has attracted attention as an excellent method for producing organic particles because of its ease of operation and high production efficiency. [0004] Patent Document 1 describes an example in which an aqueous d...
