Definitions
- the present invention relates to a pigment dispersant, a pigment composition, and a coloring composition that are suitably used for printing inks, paints, resin colorants, inkjet inks, color filter inks, and the like.
- the present invention also relates to a color filter used for a color liquid crystal display device, a color image pickup tube element and the like.
- pigments are dispersed in a fine state to exert a high coloring power, and have appropriate properties such as clear color tone and gloss of printed or coated products. Moreover, the labor and energy at the time of manufacturing printing ink and a coating material can be reduced significantly by dispersing a pigment in a stable state. Furthermore, a dispersion in a stable state is generally excellent in storage stability.
- pigments used in printing inks and paints are often fine particles in order to achieve a clearer color tone, and as a result, the cohesion between the pigment particles becomes stronger and the above-mentioned suitability is imparted. Is often difficult.
- a pigment derivative in which a functional group such as an acidic group, a basic group, or a phthalimidomethyl group is introduced into an organic pigment has been developed and has been effective.
- the pigment derivative since the pigment derivative has an intrinsic strong color because it uses an organic pigment as a base skeleton, it may be significantly restricted when used for a pigment having a different hue.
- diketopyrrolopyrrole pigment particles such as printing inks, paints, especially ink jet inks, color filter inks, etc.
- the diketopyrrolopyrrole pigment dispersant described in Patent Document 1 is used.
- this pigment dispersant is excellent in dispersibility, the dispersion has a problem that sharpness (lightness) is lowered.
- a color filter is a fine filter segment in which two or more kinds of fine band (striped) filter segments having different hues are arranged in parallel or intersecting on the surface of a transparent substrate such as glass. Are arranged in a constant vertical and horizontal arrangement.
- the filter segments are as fine as several microns to several hundreds of microns, and are arranged regularly in a predetermined arrangement for each hue.
- a transparent electrode for driving liquid crystal is formed on a color filter by vapor deposition or sputtering, and an alignment film for aligning liquid crystal in a certain direction is formed thereon. The process of forming these transparent electrodes and alignment films is generally performed at a high temperature of 200 ° C.
- a method for producing a color filter a method called a pigment dispersion method using a pigment having excellent light resistance and heat resistance as a colorant is mainly used.
- color filters manufactured by the pigment dispersion method generally have a problem that the degree of polarization controlled by the liquid crystal is disturbed due to light scattering by the pigment. Therefore, the light leaks when the light must be blocked, or the transmitted light attenuates when the light must be transmitted. Therefore, the luminance ratio (contrast) on the display device at the time of blocking and transmitting. The problem is that it is low.
- anthraquinone pigments, perylene pigments, diketopyrrolopyrrole pigments and the like have been conventionally used for the production of red filters.
- particularly diketopyrrolopyrrole pigments have good color characteristics when formed into a coating film, and are often used for this purpose.
- pigments having high coloring power and clear tone have fine primary particles.
- pigments used for color filters are often further refined than conventional pigments in order to improve the contrast of the coating film.
- Examples of methods widely used as a pigmentation method for preparing fine pigment particles include a solvent salt milling method.
- the pigment is added together with commonly used grinding aids such as inorganic salts and solvents, pigment particles may grow at the same time due to the heat generated during grinding and the solvent added as a dispersion aid.
- the mechanical force is applied for a long time, the state of the pigment particles becomes unstable, causing changes such as crystal transition. In some cases, a fluorinated pigment cannot be obtained.
- pigment dispersant improve the affinity between the pigment and the vehicle, and stabilize the dispersion.
- Agents are disclosed.
- pigment derivatives in which functional groups such as acidic groups, basic groups, and phthalimidomethyl groups are introduced into organic pigments
- resin-type dispersants in which acidic groups and basic groups are introduced into some acrylic polymers and polyester resins have been developed. It is used alone or in combination, and the effect is obtained. Some of these have an effect of preventing pigment crystal growth.
- the effect of preventing pigment crystal growth of conventional pigment dispersants is that highly finely divided pigment particles, such as printing inks, paints, especially ink jet inks, and inks for color filters, are sufficient to achieve high sharpness. It is not always sufficient to obtain it stably.
