preparation example Construction

[0210] As a preparation method of the dispersion liquid, the (B) dispersant can be mixed with the (C) solvent and stirred, and after the dispersant solution is prepared, the color material (A-1) and other optional ingredients can be mixed into the dispersant solution. The components are dispersed using a known mixer or disperser to prepare a dispersion.

[0211] Examples of the dispersing machine for dispersing treatment include roller mills such as two-roll and three-roll mills, ball mills such as ball mills and vibrating ball mills, bead mills such as paint conditioners, continuous disc bead mills, and continuous ring bead mills. machine. As preferable dispersion conditions of the bead mill, the diameter of the beads used is preferably 0.03 to 2.00 mm, more preferably 0.10 to 1.0 mm.

[0212] Specifically, a case where pre-dispersion is performed using 2 mm zirconia beads having a relatively large bead diameter and main dispersion is further performed using 0.1 mm zirconia ...

Embodiment

[0316] Hereinafter, the present invention will be specifically described with reference to examples. The present invention is not limited by the above description.

Synthetic example 1

[0317] (Synthesis Example 1: Synthesis of Dimeric Triarylmethane Dye)

[0318]Referring to the production methods of Intermediate 3 and Intermediate 4 described in International Publication No. 2012 / 144521, 15.9 g (yield 70%) of a dipolymerized triarylmethane dye represented by the following chemical formula (1) was obtained.

Abstract

Provided is a colorant dispersion liquid that enables the formation of a coating film having an excellent heat tolerance and high brightness while adjusting the film color to a desired tone. The colorant dispersion liquid comprises a colorant (A), a dispersant (B) an a solvent (C), wherein the colorant (A) contains at least a colorant (A-1) in which a cation represented by general formula (I) forms a salt together with a monovalent anion represented by general formula (II). [In general formulae (I) and (II), the meaning of each symbol is as defined in the description.]

Description

technical field [0001] The invention relates to a color material, a color material dispersion, a colored resin composition for a color filter, a color filter, a liquid crystal display device, and an organic light-emitting display device. Background technique [0002] Thin image display devices such as monitors, so-called flat panel displays, are characterized by being thinner than cathode ray tube displays and occupying no space in the depth direction, and have been put on the market in large numbers. Regarding its market price, with the progress of production technology, the price tends to be appropriate year by year, and then the demand expands, and the production volume also increases year by year. In particular, color LCD TVs have almost become the mainstream of TV. In addition, recently, organic light-emitting display devices such as organic EL displays with high visibility due to self-luminescence are also attracting attention as next-generation image display devices....
