Abstract
According to conventional art the problem of point, problem of the invention is to provide color characteristics excellent colored filter viridine green dispersion.Specifically, it is the colored filter viridine green dispersion that includes C.I. naphthol greens 59 as pigment in the colored filter viridine green dispersion comprising pigment, pigment dispersing agent and solvent.
Description
Technical field
The present invention relates to the system for the optical color optical filter for being primarily used to transmission-type or reflection type color liquid crystal display
Viridine green dispersion and green coloring composition used in making.
Background technology
Colored filter is made up of following：Two or more different form and aspect of configured in parallel on the surface of the transparency carriers such as glass
Fine band (band), or fine pixel is configured according to arrangement fixed in length and breadth.Pixel Dimensions are number 10~number
100 μm of so fine shapes, and each form and aspect fitly arrange according to the order of regulation.Accordingly, with respect to colored filter
Manufacture method, it is proposed that various methods.
Because colored filter needs high transparency, therefore, by the following method, i.e., entered using so-called decoration method in the past
Row manufacture：3 following processes are repeated, weight is added in the aqueous solution of the stainable natural polymer such as gelatin, casein
The emulsion such as chromic acid make its sensitized, and using photoetching process formation pattern of pixels, above-mentioned pattern of pixels then is dyed into desired face
Color ultimately forms the transparent coloring fine pattern of 3 colors so as to obtain multicolour pattern.
In recent years, along with the maximization of colour liquid crystal display device screen, the variation of purposes, generate raising heat resistance,
The demand of the reliabilities such as light resistance.
For the demand, as the color material of colored filter formation, the organic of light resistance and excellent heat resistance has been used
Pigment replaces color characteristics excellent but heat resistance or the limited dyestuff of light resistance.
When manufacturing colored filter using the radioactivity-sensitive colored resin composition for having disperseed organic pigment, in transparent base
On plate or it is pre-formed on the substrate of the light shield layer of desirable pattern the radioactivity-sensitive coloured tree that coating has disperseed organic pigment
Oil/fat composition, after drying, exposes into desired pattern by dry film and develops, so as to obtain the pixel of colors.
However, in the case of using the radioactivity-sensitive colored resin composition of organic pigment has been disperseed, for example, saturating
In the colored filter of 3 primary colors that blue, green, red light is arranged on bright substrate, it is however generally that, only it is single pigment, very
Each is seldom arrived as the spectrophotometric spectra of colored filter, it is therefore desirable to prepared using two or more pigment.
On green colored filter, as described in the grade of patent document 1~3, generally C.I. pigment Green 7s,
36th, the yellow uitramarines such as C.I. pigment yellow 13s 9,17,128,150,155,185 are added in the viridine greens such as 58 to adjust spectrum and bright
Degree.
However, it is lightness to improve transmissivity, and colour purity etc. is lifted, to the requirement liter of the color characteristics of colored filter
Height, is only that raising of the combination of these pigment types to the color characteristics as colored filter has limitation.
There are C.I. naphthol greens 59 as the excellent viridine green of color characteristics, but technology is produced on due to dispersible pigment dispersion
On have difficulties, therefore be not practical so far.

The composition disperseed selected from colored filter with viridine green in anti-corrosion agent composition 1~8 is uniformly mixed into as table 3
Pigment proportion, the colored filter for obtaining embodiment 1~2 and comparative example 1~10 disperses anti-corrosion agent composition with viridine green.
Table 3
(evaluation)
<Colored filter disperses the evaluation of the color characteristics of anti-corrosion agent composition with viridine green>
The colored filter of embodiment 1~2 and comparative example 1~10 is disperseed into anti-corrosion agent composition with viridine green to be applied with sol evenning machine
It is distributed on glass substrate.Then, preliminary drying after 3 minutes, is exposed with high-pressure sodium lamp at 100 DEG C, and then rear 30 points of the baking at 230 DEG C
Clock.Then, with spectrophotometer (Shimadzu Seisakusho Ltd.'s company system, UV-2500PC, 2 ° of visuals field of illuminant-C) determine embodiment 1~2 and
The color characteristics (x, y, Y) of each resist of comparative example 1~10.In embodiment 1~2 and comparative example 1~10, try to achieve in colourity
Thickness, lightness Y under x=0.224, y=0.669.
According to the embodiment 1~2 of the example according to the present invention, understand due to colored filter viridine green resist
Composition Y value is high, and thickness is small, therefore possesses the appropriate optical property as colored filter.
On the other hand, according to without using C.I. naphthol greens 59 using other pigment comparative example 1~10, even if x and y value with
Embodiment is identical, but because Y value is low, therefore can not suitably be used as colored filter.
As shown in Table 3, used as viridine green the colored filters of C.I. naphthol greens 59 with viridine green dispersion i.e.
Make the small lightness of thickness still very high.
