Description
Technical field
The present invention relates to the colored filter Red Pigment Dispersion anti-corrosion agent composition of the colored filter used for color liquid crystal display arrangement, imageing sensor etc.
Background technology
The colored filter that color liquid crystal display arrangement etc. utilize is made up of following: on the surface of the transparency carrier of glass etc. two or more different form and aspect of configured in parallel fine band (band) or fine pixel is configured according to sequence fixing in length and breadth.Pixel Dimensions is several 10 ~ several 100 μm of fine like this sizes, and each form and aspect fitly arrange according to the order of regulation.
Color liquid crystal display arrangement is make the white light from backlight through above-mentioned colored filter thus painted, and on picture color display.Therefore, as the key property of colored filter, high transparent is needed.Therefore, carry out dyeing and so-called decoration method etc. manufacture by using the dyestuff of excellence in color characteristic to be distributed in resin with molecular state in the past.But, in recent years along with the variation of purposes, when needs improve thermotolerance, photostability etc. for long term reliability, organic pigment can be used replace to the limited dyestuff of the raising of its reliability.In addition, about the autofrettage of colored filter, it is also proposed the various methods such as print process, ink-jet method, photoetching process.
And then, recently especially in order to advance the power saving of the liquid crystal indicator carrying instrument, need the colored filter with following pixel: the permeability improving visible ray, the display frame become clear can be obtained more efficiently in limited electric consumption, and the height contrastization of the high-precision refinement bringing general image can be realized.
The performance largely depending on the pigment be dispersed in each color pixel of colored filter through, contrast performance of above-mentioned visible ray, for the pixel of redness, only use a kind of pigment is difficult to the performance needed for realization, thus proposes the toner pigment share other.
Such as, propose the paratonere 177 relative to main red pigment, share the system (for example, referring to patent documentation 1) of toning red pigment.At this, as toning red pigment, the red pigment in 535 ~ 555nm wavelength region may with maximum absorption band can be set forth in, namely paratonere 5,9,10,17,48:1,48:2,48:3,48:4,52:2,119,166,216,224,226.But, for the common system of above-mentioned red pigment, limit is existed to the raising of above-mentioned transmitance, contrast performance.
And then, propose the system (for example, referring to patent documentation 2) share paratonere 177 or 254 in the paratonere 242 of main red pigment as toning red pigment.And, also proposed the system (for example, referring to patent documentation 3 and patent documentation 4) etc. share the red pigment of paratonere 177,207,209,224,242 etc. in the paratonere 254 of main red pigment as toning red pigment.
But, during as body pigment use paratonere 242, the partially yellow such problem of tone can be produced.On the other hand, when using paratonere 254, transmitance increases, but reduces the simultaneous contrast that the thickness of coloring film thickens.And then, from the characteristic of pigment, also there is the problem that solvent resistance is deteriorated or thermotolerance variation (generation sublimate) is such.
And in recent years by also adopting the backlight etc. of LED as light source, the color rendering region of colored filter expands.But because the wavelength being radiated at the light on each is different, available coloring pigment is limited.Such as, when using LED as the backlight of light source, for the combination of pigment as described above up to now, have to improve further the pigment concentration of pixel from the relation in the absorbing wavelength region of light.Therefore, exist as Red Pigment Dispersion anti-corrosion agent composition and need high concentration, the manufacture of composition self, through time stablize the problem of preserving and becoming difficulty.If in contrast, make the concentration that pigment concentration becomes in the past common, then the thickness that this time can be produced as the pixel film obtaining required color density becomes blocked up, manufactures colored filter and becomes the such problem of difficulty.
In order to solve this problem, when using pigment red179, the paratonere 208 of wavelength of the light be suitable for from LED illumination, even if the pigment concentration not improving pixel also can obtain color density, thickness becomes in controllable scope, but within the system, there is brightness and reduce such problem in essence.
And then, maintain high colouring power as the wavelength relative to the light from LED illumination and improve the method for brightness, thinking the red pigment (for example, referring to patent documentation 5) using paratonere 221 grade.
But, increase and guarantee that dispersion liquid ageing stability becomes difficulty because the viscosity of paratonere 221 in dispersion step raises, so the mobility, the ageing stability that are applicable to of dispersion liquid cannot be obtained by known method.
