Specific embodiment
The present invention is to be related to the colored filter Blue pigment dispersion composition and colored filter indigo plant of display device
Color pigment disperses the invention of anti-corrosion agent composition, can also be not to be as colored filter Blue pigment dispersion composition
The composition of resist.
No matter which kind of composition, the colored filter Blue pigment dispersion composition of the display device of that present invention is that can be used for showing
The composition of the colored filter of device, as the effect of the invention by its bring, it is possible to provide there is high coloring power and highlight
Degree, therefore the colored filter of display device Blue pigment dispersion composition and colored filter Blue pigment dispersion are against corrosion
Agent composition.
The present invention is colored filter Blue pigment dispersion composition and divides relative to the colored filter blue pigment
Powder composition has cooperated colored filter Blue pigment dispersion made of alkali soluble resin, photopolymerizable compound etc. against corrosion
Agent composition.
And colored filter Blue pigment dispersion composition includes light-cured type and non-light-cured type.
[composition of A. colored filter Blue pigment dispersion composition]
Colored filter of the invention with Blue pigment dispersion composition mainly by coloring pigment, pigment dispersion aids, resin and
Organic solvent is constituted, and can cooperate pigment dispersing agent.
(pigment)
The colored filter of the display device of that present invention uses Blue pigment dispersion composition to contain C.I. pigment blue 15 as pigment: 6
(C.I.PB15:6) with Phthalocyanine Zinc class viridine green.
Phthalocyanine Zinc class viridine green refers to containing the pigment with the compound of the phthalocyanine structure of metal centered on zinc.In addition,
Can be with C.I. pigment blue 15: 6 cooperate in the range of play effect of the present invention, can also be for by with the metal centered on zinc
The pigment that the compound of phthalocyanine structure and the complex of other pigment are constituted.
As Phthalocyanine Zinc class viridine green, C.I. naphthol green 59 (C.I.PG59) and C.I. naphthol green 58 (C.I.PG58) can be used
One or more of.When adding the pigment with the compound of the Phthalocyanine Zinc structure, colored filter Blue pigment dispersion is made
When composition and the colored filter of display device Blue pigment dispersion anti-corrosion agent composition, it can be improved as the bright of composition
Brightness, transmissivity when degree or formation film.
Have the colored filter of display device of the organic EL light source of white etc. in Blue pigment dispersion composition in the present invention,
Total solid content of the total usage amount of coloring pigment relative to composition, it is preferably 5~80 mass % in terms of quality ratio, more excellent
Select 20~50 mass %.
In order to assign high brightness, comparison to the colored filter of the display device of that present invention Blue pigment dispersion composition
Degree, as above-mentioned each coloring pigment, it is preferable to use the pigment of micronized processing.By carrying out micronized processing, can make to colour
The primary particle size of pigment is finer and uniform.
As the processing of above-mentioned micronized, such as be preferably carried out the micronized processing: will comprising untreated coloring pigment,
Water-soluble inorganic salts are (for sodium chloride, barium chloride, potassium chloride etc., preferably sodium chloride, as used water-soluble inorganic salt
Preferably 50 μm or less of average grain diameter) and do not dissolve the water soluble disperse medium (alkoxyl alcohol of above-mentioned water-soluble inorganic salt substantially
Class, di-alcohols, ethers etc.) mixture by kneader, roller mill, ball mill, grater (attritor), sand mill,
Institute is made on the well as planetary stirring machine (planetary mixer) that Japanese Unexamined Patent Publication 2006-192385 bulletin is recorded
The TRI-MIX (trade (brand) name) of Co. Ltd. system, as continuous single-shaft kneading machine Asada Iron Works Co., Ltd. miracle
After the kneading device of KCK etc. is kneaded, the salt mill for removing above-mentioned water-soluble inorganic salt and above-mentioned water soluble disperse medium is carried out
Processing.
In turn, the viewpoint equably being miniaturize according to the crystal growth that can inhibit coloring pigment, preferably in aftermentioned pigment point
Micronized processing is carried out in the presence of scattered auxiliary agent.The usage amount of pigment dispersion aids at this time is relative to 100 mass of coloring pigment
Part is 0.5~30 mass parts, preferably 3~10 mass parts.
And except C.I. pigment blue 15: in addition to 6, within the scope of the effect of the invention, such as C.I. pigment can be shared
Blue pigment well known to blue 15:3 (C.I.PB15:3), C.I. pigment blue 16 (C.I.PB16) etc..In addition, as viridine green,
In the range of reducing brightness, contrast within the scope of the effect of the invention and not, such as C.I. pigment Green 7 can be used
(C.I.PG7), C.I. pigment green 36 (C.I.PG36) etc..
But the pigment of inadequacy violet is preferred.
(pigment dispersion aids)
As the pigment dispersion aids of Blue pigment dispersion composition of the colored filter for the display device of that present invention, preferably
With C.I. pigment blue 15: importing on the basic framework that 6 (epsilon copper phthalocyanine pigment) have same or similar molecular structure can be improved
With the acidic-group of the compatibility of organic solvent, so that the pigment dispersion aids of the pigment dispersing agent with acidic-group be made.
Such pigment dispersion aids are in the micronized of pigment, the process of dispersion, since the partial adsorbates of basic framework are in pigment table
Face, and the affinity with organic solvent, pigment dispersing agent can be improved in acidic-group, so have fine when dispersing pigment
Change, after dispersion through when the raisings such as dispersion stabilization effect.In addition, pigment dispersion aids itself are dissolution in organic solvent
Or the state dispersed with particle, due to being adsorbed in larger scope in surface of pigments, so further preferably.
Wherein, whens using as acidic-group with sulfonic pigment dispersion aids etc., good result can be obtained.
In the colored filter pigment dispersion in Blue pigment dispersion composition, with acidic-group of the display device of that present invention
The usage amount of auxiliary agent is 0.5~30 mass parts relative to 100 mass parts of coloring pigment.When the above-mentioned pigment with acidic-group point
When dissipating the content of auxiliary agent less than 0.5 mass parts, pigment dispersion effect is reduced, on the other hand, when more than 30 mass parts, pigment point
Scattered effect does not further increase.
The above-mentioned pigment dispersion aids with acidic-group are as follows:
(1) using the coloring pigment for carrying out micronized processing there is no the pigment dispersion aids with acidic-group
When, in the coloring pigment dispersion handled through micronized, relative to 100 mass parts of coloring pigment, using with acidic-group
0.5~30 mass parts of pigment dispersion aids, preferably 3~15 mass parts.
(2) using the coloring pigment for carrying out micronized processing in the presence of the pigment dispersion aids with acidic-group when,
Color pigment uses 0.5~30 mass parts of pigment dispersion aids in micronized processing, relative to 100 mass parts of coloring pigment, excellent
3~15 mass parts are selected, the coloring pigment handled through micronized has in dispersion relative to 100 mass parts use of coloring pigment
0~29.5 mass parts of pigment dispersion aids of acidic-group, preferably 0~12 mass parts.
And the usage amount of the used pigment dispersion aids with acidic-group is handled with through micronized in micronized processing
Coloring pigment usage amount of used pigment dispersion aids with acidic-group when pigment disperses summation relative to
100 mass parts of coloring pigment, the pigment dispersion aids with acidic-group are 0.5~30 mass parts, preferably 3~15 mass parts.
More specifically, as the pigment dispersion aids with acidic-group, the pigment used with sulphur acidic-group is dispersed
The case where auxiliary agent, is illustrated.
As blue pigment make C.I. pigment blue 15: when 6 dispersion, as described above, by as epsilon copper phthalocyanine pigment and C.I. pigment
Blue 15:6 is the sulfonated bodies of the pigment and/or pigment with anthraquinone skeleton of identical skeleton as pigment dispersion aids.
